Okay,
I am revisiting my generator problem. I have looked over the Operator's manual
I have spoken with Keith Reich ....couldn't help
I have reread the posts here....
I have had the batteries charging off the land line . BOTH Magnum and my new Victron say that I have 100% SOC and 13.3 voltage
When I press the gen start, I just get the ticking sound that most here think is the fuel pump
I need to find, and then, switch the relays. What's an ES52?
Don't want to sound stupid, but
Where Are They?
Sven, John.....come on now....
Someone can guide me through this.
Got my voltage tester in hand......
And yes, I will probably buy some batteries here. Can't always get what you want.........

Have you placed a call to Jeff at Powertech, he will have your answers. +18007600027

If the gen has the control box on top pull gen out and take metal box cover off. Inside is the ESboard with relays. If you do not have new ones only thing you can do is swap them to see if it starts. If it does then it will most probably stop once filter fuel is used, but will tell you that it is relays that need to be changed out.
There is possibly also the latching breaker in there but again if you do not have a spare you will have to steal one out of bathroom lighting which if like ours is in the mid basement behind panel on wall. Like Bruce said call Jeff but he was not much good to me as mine was different issue. Mike may be best one to PM.

Haven't called Jeff yet.
If I have to pull the gen out, I need to disconnect exhaust.?
Never have tried that.
Also....
when I press the charger button on my Magnum, the green light is blinking???
It says charger standby and full charge at 12.8 v
Why is it blinking?

Re: No generator

Reply #55 – December 07, 2020, 06:33:59 pm

Read the Magnum book
It says, if blinking, in Standby mode, not allowing incoming AC to charge batteries.
Said to "stop" blinking press On off charger button
I did
Said if not, to disconnect/ reconnect ac power
I turned off main breaker
Still blinking

Check all of the wire connections at the ES52 board and at any white plugs, etc. My problem I found to be either loose or broken wires either at the ES52 or at the white plug. When I moved the ES52 and relays to the side compartment I found a broken wire also that was keeping the dash switch from working properly.

With Glenn having a '01 coach he may have the Powertec enclosure rather than the Foretravel in house enclosure. If so his electronic module is harder to find and get to to trouble shoot. It could be the start switches have gotten out of time or one has failed.

Glenn check your P/Ms.

Okay,

(1) When I press the gen start, I just get the ticking sound that most here think is the fuel pump
I need to find, and then, switch the relays. What's an ES52?
(2) Don't want to sound stupid, but

(3) Got my voltage tester in hand......
And yes, I will probably buy some batteries here. (4) Can't always get what you want.........

(1) Beginning here, the first thing you need to do is find out exactly what is ticking. Ticking describes a wide range of sounds and each and every one of them leads to the solution. Different solutions each and every sound, but the solution.

(2) Realizing that you don't know is the beginning of knowledge. Well the acquisition of knowledge.

(3) (Friendly Snark) Oh boy.

(4) But if you try some time, you get what you need.

We have a classic Onan Emerald 7.5 KW generator, but "WE" also have education and experience building industrial control systems. I am making an educated guess that ES 52 is an "ice cube" relay. something about the size of an ice cube that can be unplugged from a socket. Someone also mentioned "latching." Relays can be made with a mechanical latching mechanism, pulse it once and it locks in the on position, pulse it again and it un-latches.

FWIW, the other half of "WE" replied to my comment that Mr. Yeager appeared humble in public. Lynn replied "My dad says that he really was like that. It may have had to do with the secrecy around most of the aircraft he flew. They met on the X-15 project."

Art the ES52 is the control module that controls preheating and start/stop functions along with shutdown due to overheat and low oil pressure. And yes there are 2 mini relays on the ES52 that I think are fuel pump and start relays. It also has lights for the various alarms.

See Mike & Pamela post #19 I think these are what you are looking for.

So our Foretravel friend in Mexico needs to accomplish two tasks.
(1) is to find the ES52 control module, read the lights, check to see if one of those relays is cycling, and swap the relays one for the other and see if the starter engages and spins the engine.

(2) Confirm that the fuel pump is the source of the ticking noise.

Then report back for further instructions?

PS When do we tell him that there is a starter solenoid to switch the heavy power to the starter?

To help out everyone as to what a DynaGen ES-52 module looks like from the side you see when you are looking for it. Once you find this, then what is in the pic. in reply 61 are what is hid inside the electrical cabinet. All you will see is the lights and sticker you see here.

Glenn this is where my Voltage regulator (your not having that problem) was located. I THINK the relays that you are looking for are under the panel on the top left side of the Generator. I THINK you have the quiet box like mine? (Someone correct me if I am wrong and will remove this post) The screws were a bear to get too and to get out. All were on the top. Ive got one now but this would have been a life saver when trying to get the screws out. I picked one up at auto zone for $6

Thanks, all
I am in touch with Mike
I have never pulled my generator out, and if I did, will it run if I disconnected the exhaust? necessary to do so?
I have an offset tool, not as cool as the one shown, and COULD try and remove the top of the box while in place.
How would I get to the relays? Looks tight
And here's the rub.....
We have no land line this morning.....electricity is "out"
BOTH my Magnum AND my Victron show 100% SOC and I am inverting at 13.1 with only 360 w of solar to help batteries
So WHY can't I turn the gen over and IF my AH isn't firing up, why not
Will be contacting Rudy next

I know when I pull my generator out, I don't disconnect the exhaust and I don't see why I couldn't run the generator when out.

I also have a thumbwheel driver like these that works well in tight spots: Amazon.com: Titan 11218 Finger Grip Drivers (3 Piece): Home Improvement
Also with mine, which is not enclosed, I found if I let the generator door (fiberglass front end of the coach) drop down a foot or so it gave me more room to get to the box. Sounds counter-intuitive but try it, may work for you. Borrow your wife's make up mirror or buy one so you can see in the box.

Are you saying that you have never run an engine with open exhaust? Never too late to start.

I would have to pull the gen out to access the screws for top of control box to check relays
Trying to find the proper procedure of " how to"
Says to disconnect flexible exhaust first...
Where?
Then.......

Glenn. Take the bolts off the slides on both side of gen. The last picture you posted show the bolt at bottom right. Then crawl underneath and at the back of gen box you will see a corrugated pipe going to small muffler. Undo clamp at joint and take that pipe off. This will allow you to pull the fen out about 10". Still tough to get all 6 screws off but u can do it. Spray them first with release oil.

oldguy,

You have the old style Foretravel in house quiet box. Yours is all together different, not bad just different.

Glenn has the new style that came from Powertec as a hole unit inside there quiet box. This is a great help as to what he has and where things are located.
