Got a response back from Damon tech. From my description of the symptoms they believe it is the battery disconnect solonoid. Will try replacing that.

Thanks Rich. It was an identical match. I found it very helpful.

Thanks Wolfe. Will do.

Since I purchased the coach batteries from Interstate last summer and they are only about a mile from me I took the coach to them to check the batteries. Batteries now fully charged. Some symptoms have been eliminated. Here is what is left. 1. No 12 volt power when on batteries. 2. 12 volt power available when on shore power and when on generator. 3. Charging current of around 13 volts present at converter output terminal when on shore power and when on genertor power, but not showing up at the batteries. 4. Charging current of over 12 volts present at coach batteries when engine is running. Could it be the battery disconnect solenoid?

I have removed the coach batteries and have them on a charger. I then started the motorhome and the earlier cycling problem I had with the solonoids has disappeared and the engine is now running just fine. Now to just figure out how to get 12 volt power back on in the coach.

I have a Progressive Dynamics Intelli Power 9200. I did check the breaker and it was good. I have identified the solenoid that is cycling about every 10 seconds and dragging the engine electrics down (dash lights dim, engine drags down). There are 2 solenoids paired together (parallel) in one mount. The top one has a sticker on it that says "ignition proof" there are other marking that indicate "coach" and "chassis" terminals. It is the bottom of these two solenoids that has no markings on it that is cycling and dragging the engine down. Could these solenoids be my problem?

Went out to start the motorhome today and........nothing. Wouldn't crank over. Tried auxillary start. Nothing again. Also found no DC power in coach when on batteries. Jump started the generator and had 110 but no 12 volt DC power to coach. Shore power has both 12 volt and 110. Coach has been plugged into shore power the entire time since last use a couple of weeks ago. Jump started the motorhome and it would run but about every 10 seconds I can hear a solenoid switch and the lights dim on my instrument panel and the coach engine starts to drag. Engine battery only showing about 7 volts as do the coach batteries. With the generator running the engine battery shows 13 volts but coach batteries still only show 7. Anybody have any ideas what kind of gremlin I'm dealing with? I am baffled.
