Glenn,

I forgot about the the latching relay in the generator control cabinet where the ES-52 is located. That relay is how the momentary manual dash switch starts/stops the generator with a push on/push off. That prompted me to look at the factory generator Auto Start wiring diagram, as used with the original generator control you replaced with the ES-52. (see attached) This may be helpful. Because of the latching relay, the factory wiring is a bit different that the wiring shown in the Dyna-Gen diagrams.


Greg - the copy you posted is for 97-99 coaches.  There's also one in the Media library that is labeled as covering through 2001 (and is actually the drawing from our 2003).  I'm sure it's the same drawing, just wanted to mention if you want a fresh copy

The selected media item is not currently available.

Thanks. Our generator has the ES-52. I knew it was a replacement, but didn't know the original control was different until I looked at that drawing today. The drawing is a scanned copy of an original from our coach manual. We have a hodge podge of factory drawings in our coach manual, including DGFE, WTFE, Special, and U320-GV. Yup, it's a bastard ...and we love it.

OK
A little confused
I'm sure the wiring wasn't touched when ES 52 changeover
I was going to jump the start at the module earlier today, but it became " big shopping day"
Sam's Club for Cape Cod Potato chips, Walmart, supermarket .......even bought a new relay for the module, just in case.......about $3.10 USD
Anyway, do I still want to do this test. Remember.....I was told the green light should be flashing " ready" ???
There is no green light
I will install the new relay, just for fun, but then do I jump it?

I get the confusion... me too, until I looked at the factory wiring diagram..
The easiest thing to do would be to plug in the new relay, discharge the house battery to under 12.2V, and see if the green light comes on/generator starts. If the green light doesn't come on, IMO, it pretty safe to assume the BCM-12 board has failed. If it does come on, and you hear the relay click, check the wiring by doing the jump test to verify the wiring from the BCM-12 to the ES-52 is good.

One more question....
What would be a good way for me to " run down " the batteries?
Can I SAFELY run the microwave for a while?
I saw the red light flashing this morning....BEFORE I installed the new relay
Then I started the generator, and the green light flashed rapidly for a few seconds
I am hopeful
When I " jump" the auto control, as described above, do I just touch the top of the plug, or do I unplug and touch one and five?
Maybe that was more than one question......

The inverter will keep the same voltage to your microwave until it shuts down. I use it to test the auto start when I get ready for a trip.

Success!!!!
Ran the microwave.....auto gen came on!!!!
Life is GOOD!!!
Thanks, EVERYONE, for your help

So what was the final solution?

To be clear, after I installed the new ES 52 control in the generator, I never "tested" the auto switch.
The first change that I made, after talking to Jack Lewis, was to change the LVCO from 12.2 to 10.5
Then, just to be safe, I installed a new relay in the auto start
Prior to resetting the LVCO, I had run down the batteries ( set at 12.2) , the inverter cut out, but the auto generator did not kick in.
So it may be the change of relay, or the change of setting, but in either case....
I'm now a Happy Camper

The default LBCO for your inverter is 10V, after a 1 minute delay. Apparently, it had been changed to 12.2V at some point. IMO, that's way too high. Jacks advice to set it at 10.5 is excellent.  ^.^d  Due to voltage sensing tolerances in the inverter, and the BCM-12, it's possible that having the LBCO of the inverter set to the same voltage as the BCM-12 never allowed the actual voltage to drop to the actual setting of the BCM-12 before disconnecting.

Great to hear you got it squared away.
