I think I found the charging solenoid in the back of the battery compartment...


The right terminal comes from chassis battery and the left comes from the house battery. Here's what I get with a volt meter:
Right terminal (Chassis battery):
Engine off/no Gennie: 12.9
Engine on/no Gennie: 13.9
Engine on/Gennie on: 13.9
Engine off/Gennie on: 13.08
Left Terminal (house battery)
Engine off/no Gennie: 12.6
Engine on/no Gennie: 12.6
Engine on/Gennie on: 13.38
Engine off/Gennie on: 13.38
Another symptom, pushing the boost button on the dash doesn't seem to do anything. I tried putting it in "store mode" then turning on a light...nothing happened of course, but I thought if I pushed the boost button, I would see a light come on...nothing happened. Also, when I had bad chassis batteries a while back, the boost didn't do anything...
I can't find any blown fuses....does this mean that what I've found is in FACT the charging solenoid and based on these readings, it needs replaced?
