And herein lies the rub with a modern high impedance voltmeter.* You need to put some stress on the cables when you measure the voltage.

Unless you load the circuit leakage current will make you thing all is good.

Good point, O T.

Glenn,

It's unlikely that your generator and inverter would fail at the same time. Therefore, I would check the main terminals on the 12V house distribution panel, I mentioned earlier, in the left side of the second bay. It's behind the white FRP cover with 3 wing nuts. (See pics). This is the point where the generator and inverter are powered from. Make sure the terminals are clean and the nuts on the posts are tight. Keep in-mind that the positive terminal is live, and not fused, when the house battery is connected, OR when the boost is turned on. Note that the generator supply is not fused. The inverter fuse is below the main terminals. If you're not certain of the condition of the house battery, disconnect the battery ground, and try this with the boost on.

Hope this helps,
Greg

UPDATE:
I appreciate all the input I received, and help from this forum.
It was a main reason that we chose Foretravel, when we never had even heard the name, before.
With help from you, I was able to pull the generator out, and control box.
I called Jeff, as directed, and was more than pleased with how quickly he was able to walk me through the diagnosis.
He had me release the ES52 from the control box, and then disconnect the blue wire going into it. He then had me touch a terminal
and she fired right up!!
Not the starter....yeah!!!!!
Need a new ES 52 sent down here, and will order a spare latch switch, while I'm at it.
One problem down........aye

Glen, will you please post exactly what Jeff told you to do and if possible any pictures of wiring concerned.
Many of us have the same unit so what to do is very important. Write it out clearly please.

John,
Thought I did in post101?
After I disconnected the blue wire from the ES52, he David to look for a unit that was about an inch square and half an inch deep with red wires going into both sides of it. It took a minute, but easily found on the right side of my control box
Then he had me touch the blue wire to either side. I went for the front One and she fired right up.
Told me bad ES52F
Will order one tomorrow, but here in Mexico, who knows when I'll see it.
I'll try and add photos when the new part comes.
The hardest part of this repair was removing the last screw holding the lid to the control box. The generator doesn't quite come out enough. Took me an hour to remove the screw. It's ALWAYS the last screw that gives you trouble. At $140/hr, let's see...........

At that rate

, you probably saved enough to buy the part that needs replacing, and maybe enough left over for a decent bottle of tequila.
The satisfaction from being able to fix it yourself: Priceless!

That es52 will hurt your wallet. Glad you got part of you problem solved

It was suggested that I buy just the relays.
I will look into that, first.
I also wanted to order a spare latch switch, but don't know where to buy one from now.
And yes....I sleep MUCH better, now. I didn't think the starter was the issue....it ran like a top, and I serviced it regularly, even with minimum use. I always exercised it, while in storage, with load.
Thanks for all the help

Glenn,

I am glad that you have made progress on trouble shooting and be back up and running soon. I may have some info on that latching relay and pill post if I can find it.

I just reread all the discussion, here.
Mike gave me the correct info, early on, regarding switching the two relays behind the EM52
I had a " high dummy factor" working, and did not understand what was CLEARLY presented to me, including pictures of the back of the unit.
As I said, the hardest part of this experience was getting the last screw off the back of the control box.
I want to thank you all, again, for your patience with me. This was new terrain for me, and I am now a whole lot more comfortable working on the generator. It is, one, well made unit, and we try and take good care of it.

Glenn,

Let me make sure when you are talking about latching switch you mean the white latching relay that is mounted on the back wall of the control box. I had to go out to the RV and look at my spare latching relay to find the number.

If so here you go:
Finder - 20.22.9.012.0000 - DPST-NO DIN Rail Panel Mount Latching Relay; 16...

https://www.digikey.com/en/products/detail/finder-relays-inc/20-21-9-012-0000/10055776

Mouser is another supplier that will have them I just don't have them bookmarked at present.

You may even be able to find them on Amazon or eBay cheaper. While the generator is out and the cover is off the control box check your relay and make sure that yours is the same. Look for the TYP 20.21 on your relay and double check the coil voltage as it should be printed on there.

There is a link on reply 36 that has the relays for the ES-52 so I just copied it so all the info is together.

Let me tie this in here as I have been ask about the ES-52.
First off it's proper name is a DynaGen ES-52
They are not special to our coach or even Powertec as lots of companies use them on there products.
Here is a link to the company site that you can go to and download some good info for those that are inclined.

Now prices are all over the board so shop around to make sure you get the best customer service for the price of the module.

Yup
That's the relays and latch
Thanks

I know there isn't an answer, but....
Why wouldn't Jeff recommend just replacing the relays and not buying a $250?? item
Or there IS an answer
He was a great help, though. So NO complaints

Re: No generator

Reply #115 – December 11, 2020, 01:22:13 pm

Glenn, if Jeff quoted you 250 for new board something does not smell good as he quoted me 500 us when I was talking to him.
Read Mike's last link to Dinagen and see section 4 in Troubleshooting for Engine not cranking. It mentions relay or fuse. Jeff wants to sell them at his price as they are in the business of making a profit etc. Normal business.

I had a " high dummy factor" working, . . .

Nothing to do with native intelligence. More like a brain cramp of brain freeze. Panic.

Example. I lost the left rear wheel from my car one week ago. I asked Lynn to come pick me up and take me to the doctor's and call a flat bed. He showed up with a floor jack and a socket set and said "Why don't we just steal one lug bolt from each of the other three wheels?"

The doctor's office called an suggested coming moving my appointment back a couple of hours.

Thought I posted this?
I just switched the two relays
Same issue...
Just the " clicking" of the fuel pump
When I touched the blue wire to the post, yesterday, it jumped to start up
Jeff did not give me a quote
I was googling a ES52 and, somehow, came across that amount. Also, a ten year old forum where one was bought on eBay for $75!
Wow!

Reply #118 – December 11, 2020, 02:17:04 pm

Tried to take picture of the contact in the right side of the control box
Pretty tight in there
Anyway, it had one red wire on the left side and two on the right
I touched the two post

Glenn,

If you touched the Blue wire to the Red wire in the pic. of reply 118 you were suppling 12vdc to the relay coil that makes it close. Now that changing relays didn't help but connecting voltage to the Blue wire did you need to check the little fuse that is located right between the 2 relays. If you look at the pic in reply 61 you can see the little yellow fuse. If it is bad replace and try again. If that fuse is good then I hate to say that something gave up internally and you will need a new ES-52.

Mike

Yeah
My thoughts exactly
I'll check the fuse and let you know, but wouldn't Jeff had told me to look at the fuse?

Jeff knows his audience, and most people look at a printed circuit board and give up.

Thats where I got mine from. But beware you have to set the dip switches to Match your old es52, or things will not work right.

How do you set your dip switches?
