Title: 1990 Foretravel Grand Villa ORED converter location?
Post by: Gayle Fischer on December 25, 2021, 05:04:46 pm
We've just purchased a 1990 Foretravel Grand Villa 3600. We're finding an issue with the batteries not wanting to charge when connected to shore power. We can't locate the converter. We've been trying to find resources online but no luck. This is not a Unihome with a basement. We've checked all compartments. Can anybody assist?

Gayle/Andy,
WELCOME to the ForeForum.
With "no basements", wonder if you have an ORED (Oshkosh Rear Engine Diesel)?
Knowing will help with the answers.

OE would very likely have been a CONVERTER. But no idea what previous owners may have done/changed in the last 30 years.

The inverter/charger in our '89 went out this last summer. It is mounted to four threaded rods up thru the floor under the fridge. I replaced it with a Parallax 45 that we purchased thru Gander Outdoors due to all the shortages and delivery dates we encountered. It was 5 star rated and only cost around $137 delivered to our door within two weeks. Identical hookup but mounting was a bit of a problem due to the unit being about 3/4" wider. I had to move two of the threaded rods over in order to fit the unit. The upper end of these rods is in the compartment under the fridge so not the easiest thing in the world to get at and do. If you go this route (and have the same mounting issue) let me know and I will try to walk you thru the changes.
I don't understand something. Why did the original call it a U280 and then state it is NOT a Unihome? Is the coach an ORED or not?????????????

I don't understand something. Why did the OP call it a U280 and then state it is NOT a Unihome?
Probably because the OP is not clear on what exactly they should call their new-to-them coach. Every Unihome is a Grand Villa, but not every Grand Villa is a Unihome. The period around 1990 is very confusing to new members, and frankly also confusing to ME. Since all the coaches in that era had a sloped "Grand Villa style" nose, they all look pretty much the same to a casual observer. You really need to know what frame, suspension, and engine is under the coach before you can properly classify it. OR, as Justin stated (above), get a look at the metal data plate.
The passage copied verbatim below is from our own ForeForum Motorcoach Wiki:
THE GRAND VILLA
In 1986, Foretravel introduced an innovative new motorhome with aerodynamic styling and an unusually spacious interior. Because of its grandeur and beauty, Marie Fore dubbed it the Grand Villa, and it quickly became one of the best-selling motorhomes in history.
After that, things got pretty confusing. For 5 or 6 years you could get a GV, OREG/OFEG/ORED/OFED, or a Unihome GV. They also offered a 'comfort ride' Torsilastic suspension- same suspension used in the old Greyhound chassis. The Torsilastic Velvet Ride suspension came on both the U225 and U240 models.
1987-1996 Grand Villa Unihome (U-280/U-300)
The 'U' series first appeared in 1988 as a designation to the Unihome body design.
During model year 1987, Foretravel introduced the Grand Villa Unihome (all mid entry coaches). The first conventional motorhome to utilize a monocoque chassis design, an eight-bag outboard suspension system, and an air leveling system. This innovative design concept revolutionized the motorhome industry and quickly set the standard by which most quality motorhomes are built today.

Post by: Pierce & Gaylie Stewart on December 26, 2021, 11:16:08 am
Chuck has it all correct except any Foretravel has nothing in common with a monocoque design. It actually has more in common with a famous Brooklyn structure that is always for sale. Someone in sales with no engineering background though he or she would make the coach a little French. Hope it was not the engineering department.

Post by: wolfe10 on December 26, 2021, 11:21:32 am
I believe it is referred to as SEMI-monocoque, as the center part of the coach structure has no frame rails (at least before slide models).

Chuck, I'm not shooting the messenger. I just hate to see that word used to inspire confidence, strength, safety when it's nothing more than a sales pitch.
It's not even close to semi-monocoque. My old GM 4107 was monocoque.
Here is Wiki's partial description: Monocoque (/ˈmɒnəˌkɒk, -ˌkoʊk/), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word monocoque is a French term for "single shell".[1]
First used for boats,[2] a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames.
With our 36 foot U300 we have 14 feet at the back of conventional frame construction, 9 feet at the front of conventional frame construction and only 12 feet in the middle of bridge construction. At the front and rear, there no steel support above the conventional frame rails so zero protection for the driver/passenger. The bridge construction amounts to about 33% of the total length of our coach. That's why they flex so much, break windshields and you best not walk out on the roof past the front cap attachment point.
Check the title in bold letters here: Chassis: Wheel-well rub marks – Low height – full Monocoque Site at: Foretravel Motorhome Chassis: Wheel-well rub marks – Low height – full...
Another quote: During the model year 1987, Foretravel introduced the Grand Villa Unihome (all mid-entry coaches) the first conventional motorhome to utilize a monocoque chassis design, an eight-bag outboard suspension system, and an air leveling system. This innovative design concept revolutionized the motorhome industry and quickly set the standard by which most quality motorhomes are built today.
I see that Foretravel has distanced themselves from the monocoque claim in the ads seen today.

Let's see if we can get back to the OP's question-- does anyone know the OE/factory installed location of the converter in a 1990 ORED?
I don't, but one way to locate it is with the batteries reasonably discharged. When on shore power, you should hear the cooling fan built into most converters. Certainly worth a "listen". Of course, if it is not working ............

So you guys have already found the build #3658. If you ever call the factory (FOT) for parts or information you should have that number handy.
Reading after the build number, you have:
A 36' SBID floor plan (side bath, island bed, dinette). 1991 Foretravel GV ORED Floorplan (http://web.archive.org/web/20190915222350/http://www.beamalarm.com/foretravel-links/models/1991-gv-ored_floorplan.html)
A Oshkosh Rear Engine Diesel chassis (probably V-917) There may be second metal plate on the wall next to driver seat showing the Oshkosh chassis data.
And the 250HP CAT 3208.

Andy says it is a 917. He's into diesel engines so is familiar with the 3208 CAT. The other is very helpful. Thanks. We'd already contacted the factory once, but under the impression we had a U 280. That's now been cleared up, thanks.
We're just getting ready to check some of the other links that were provided. He leaves this up to me... ;)

We've found, based on VIN code, that our build is actually a (K) 1989 but is titled as a 1990. This explains why we were having a harder time finding info to match all the features, hence our confusion into thinking this was a U280. Previous owner no longer had any manuals or pertinent info from the manufacturer.
Are we a little green? Yep, & aiming to fix that! ^.^d

Yes, Andy did, in the dump compartment. It appears to function on both shore & generator power, but not well. We know we need new batteries. Likely need to upgrade the converter, also. It sat for 10 years in storage, so... Thankfully, it was stored inside. Only 54k+ miles.

Start by replacing the batteries.
THEN, see if the converter will charge them.
BTW, let us know what converter you have!

Post by: Chuck & Jeannie on December 28, 2021, 05:25:52 pm
We know we need new batteries. Likely need to upgrade the converter, also.
See if you can find any kind of ID plate or make/model info on the existing converter. If you can tell us what kind of converter you have, we can offer totally biased opinions on whether or not it is worth keeping.
By the way, we LOVE helping (or is it enabling?) other members to find ways to spend their money! b^.^d
I will offer a slightly different viewpoint from Brett. IMO, the safest way to approach dealing with both batteries and converter, is to take care of the converter first. In general, the archaic converter/battery charger technology from the late 80's era was rudimentary, at best. They are often referred to (not in jest) as "battery boilers". They usually feature a fixed voltage charge rate that is not ideal for maintaining your batteries.
There are many threads on this Forum dealing with the various ways to upgrade the battery charging capability on older coaches. It is important to consider HOW you intend to use the coach, and also what (if any) your future plans might be as far as other upgrades. Take time to do some research before you buy any equipment. If you decide to replace the OEM converter, I think it would be advantageous to do so before you purchase new (expensive) batteries. But that's just my O-pinion...
Title: Re: 1990 Foretravel Grand Villa U280 converter location?
Post by: nitehawk on December 28, 2021, 05:44:26 pm
For what it is worth: We wanted the info off our convertor/charger but couldn't read the info plate because it was on the top of the unit and the unit was up close to the ceiling of the compartment. So we (the DW & I) used a small mirror and a flashlight to aid in getting a decent view of the unit. The DW even took a picture of the mirror reflection image with her cell phone. Hints here: It is easier to see if the accumulated dirt and dust of the ages is wiped off first before taking a picture. Measure the width, height, and length of the existing unit so you will know what size to strive for.

Brett, the converter charged as Chuck advertised, a "battery boiler". Andy had to unplug it while on shore power. He's doing some research on replacing the converter. All this information is extremely helpful!
Thanks also for links for the OSHKOSH 917 chassis. Something Andy thought he'd run across but couldn't relocate the info.
Since we didn't receive any manuals, with the exception of the microwave/convection, we're trying to build a binder of resources. I haven't yet figured out how to create my own album here although we've added some manuals that we've found elsewhere that weren't yet on the forum.
Many thanks.

Before spending $$$, please use a DIGITAL VOLTMETER to verify voltage when the converter is working. They start under $20 and are a "must have" for any RV.
An "over-achiever" converter and a battery with one bad cell will give exactly the same symptoms.
Said another way the smartest charger in the world told to float voltage at 13.2 VDC will massively overcharge/boil the fluid from a battery with a bad cell. Yes, charging a 10 volt battery (one bad cell) at correct voltage for a 12 volt battery will boil the heck out of the battery.
Let us know what you find.

I'm convinced that the intelli charger roasted my batteries and caused various issues in the 4 yrs it was used. I now have a power max 60 amp charger and it looks like it does all of the correct stuff. For the 90 and early buses that have very little 12 v powered items , 50 amps should suffice. The single largest draw on my 12 v side is the sound system. I added a 2000 watt pure sign wave inverter to run my work station and my dorm sizes resi fridge. The fridge draws 30-50 watts and my 2 fresh rural king batteries run it easily 24 hrs.

I also have the " split system" , with the converter in the electric/ wet bay and the inverter mounted in the forward bay. Mine is also using the threaded rod arrangement and it works perfectly. As part of the renovations replaced unit with a Progressive Dynamics 9280V 80 amp smart charger. As you can see from the attached picture, works great. Lots of air circulation. Guess I could have gone with a 60 amp, but like grandpa said " a good big horse will beat a good little horse every time" Up front changed out the Prosine original inverter unit for a Renogy 2000 watt Full Sine Wave Inverter. The Prosine was working fine But more and more of our electronic stuff looking for a clean power source.

Brian,
Are you looking for a smart charger or an inverter/charger?
If just smart charger, what size battery bank (in amp-hrs) do you have and is how quickly it will charge the batteries important? What kind of batteries-- wet cell, gel, AGM, Li?
If inverter/charger, what size battery bank (in amp-hrs) do you have and what do you want to be able to run on the inverter portion?
See, you KNEW there would be a TEST!

Hahahaha Of course,
I think its just a charger from the diesel alternator , I dont really know what it is, OEM equipment, That Thing hanging down in the locker under the Icemaker, With the battery cables hanging off it, But Im not sure if it overcharges the batterys or not, or if it charges AGMs. The Alternator does charge the batterys when Im driving it, I did have 400 AH of lead acid batterys originally, Their all dead, over 20 years old,
I would rather change it out if there is a possibility it will kill my new AGM Batterys, or cook them, Its hard to get lead acid batterys here now, Or extremely expensive,
I intend living in my Coach full time and travelling, Now my boating days are over, I fell over on a slippery wharfe and near tore both my arms off,
I dont need an actual Invertor, As everything I have is 12 volts,
I will be putting in 600 AH of AGMs, Plus one AGM, Starter Battery, 900 CCA, 75 AH, It flicks over and starts my 300 Horsies instantly,
I have 700 Watts of Solar Panels on the roof, With a 40 amp controller, This all is proven and works, As I have the same identical setup on my boat, With a 3000 invertor for 240 volts, Freezer, Laptop, Etc, In two hours, I go from 12.2 Volts to 13.4 volts, First thing in the morning sun, on a 770 AH sealed lead acid battery bank, 7 x 110 AH Battery Bank, But I dont have room in the generator locker to get that many Batterys in there, I removed the Generator from the coach,
Thanks Brian.

Post by: wolfe10 on January 14, 2022, 09:09:47 pm
OK , let's clarify the charging systems-- at least the ones that came from the factory:
The engine-driven alternator, through the diode-based battery isolator charges both house and chassis battery banks.
Completely separately, there is a 120 VAC converter that can charge the house bank only when on 120 VAC shore power OR from the generator. I believe it is this converter that you are talking about.
Just like on your sailboat, there are different "capabilities" in alternating current converters to charge the house bank. The better ones are "smart", just like in the marine industry and go through bulk, absorption and then float stages. Some also have temperature compensation either built in or as an accessory. And rather than referring to them as converters, they are smart chargers. The do the same thing, turning 120 VAC into 12 VDC battery charging.
While even a 30 amp smart charger could likely keep up with your 12 VDC consumption, the other issue is how quickly it can charge the battery bank. Having to run the generator an extra 2 hours to charged the battery bank would not be very efficient.
Now, for you, there is another issue. Since down under you use 220 VAC 50 HZ, you have to decide if you want your new device to run on shore power or on your generator. Yes, if the generator has not been changed/modified, it will be 120 VAC 60 HZ.
And another option if the original converter is working (from generator) is to leave it in place and get a smart charger that works on Australian current for when you are plugged in.

Sorry to pinch your thread, Gayle, I was even greener than you when I bought my 1989 ORED Grandvilla, , I bought mine Sight unseen off the internet from another country, Then imported it from Texas, via California, Japan to Australia,
All my questions apply to your coach too, Well most of them, I learnt most of what I know about my Coach from the Grouse Helpfull people on here, And there is a lot to learn,

OK , let's clarify the charging systems-- at least the ones that came from the factory:
The engine-driven alternator, through the diode-based battery isolator charges both house and chassis battery banks.
Will the OEM engine driven alternator, Charge AGMs with out cooking them, Or is it regulated to stop charging when the batterys are full, ????????????? The alternator charges both my battery bank and my starter battery when I am driving, But I dont know if it stops charging when the Batterys are topped up,
Would I need a Smart charger for the Engine Alternator, To avoid overcharging, My solar Panels wont over charge my batterys, They are fully regulated,

Now, for you, there is another issue. Since down under you use 220 VAC 50 HZ, you have to decide if you want your new device to run on shore power or on your generator. Yes, if the generator has not been changed/modified, it will be 120 VAC 60 HZ.
And another option if the original converter is working (from generator) is to leave it in place and get a smart charger that works on Australian current for when you are plugged in.
Thanks Brett, My Generator has been pulled out Totally, I have my battery bank in that locker now,, My shore power is 240 Volt, 50 Htz I have a Transformer to run the coach from 240 volts to 110 volts, Shore power,
But I am trying to make the coach self sufficient on Batterys and Solar alone, AC not included, I will be Free Camping, So no shore power available, Living on my boat full time for the last 11 months, mainly on the hook, I know how much 12 volt usage I require to keep ahead of the Batterys going flat, 700 Watts of solar and 600 Ahrs of Battery, I should be okay, If not, I can always put more solar on the roof, Its very cheap here, Another 700 Watts of solar on the roof is only $260-00. Delivered, 48 x 28 inches x 2, We dont get the prolonged cold and cloudy days you get over there,, I even disconnected the heaters as I will never use them, Even down here in the cold south of OZ, Minus 4 Celcius is Max,
That 120 Vac convertor is what I didnt know, what it was or did,
Thanks Brian,

Brian,
The 120 VAC converter, if still original provides a constant 13.XX volts to charge the house battery bank and the amps it can provide should be listed on the unit. If not original, it could have been replace with a more modern 3 stage unit.
What is the make and model of the converter?
So for solar charging of the battery and your use of 12 VDC in the coach, it does nothing.
It would only be useful if you are on shore power and provide the converter with 120 VAC through your transformer.
