Thanks for all the help above...
Problem again with my salesman solenoid - I have been disconnecting 120v power and 12v power from the motorhome while replacing roof A/C capacitors, new shrouds, and general clean-up. Needed to have all power off.Current state (pun intended) is that some of the 12v works in the mh but not everything. For example, the A/C thermostats work, but some of the 12v lights and the holding/water/battery full panel do not work.It seems that I have two solenoids for 12v power. I can test with a 12v probe and see no power getting across one of the solenoids. It is getting very hot though, so I disconnected the house batteries for now.I have a new solenoid on order - should be here in a couple of days.I also plan on just jumping the "bad" solenoid to see if that solves the problem (at least for now).However, it seems strange to me that the "bad" solenoid is getting so hot (with the house batteries connected). Hot as in can't keep a finger touching it. Does that make sense? I have tried to make sure most 12v items are off in the mh.Also, when I jump the solenoid, I plan to use 4 gage battery wire (about 8") with eyelets. Do I need to remove the two control wires to the solenoid? (WHITE - I assume ground and PURPLE - I assume control from the switch up by the passenger's seat)?I'm hoping that the heat issue goes away (by jumping and/or with the new solenoid).Thanks everyone for the help so far. I think I'm getting close to solving this and several other gremlins - in general the mh seems in very good shape, I just don't think some of these things were maintained much for the past few years (before my wife and I purchased a couple of months ago).My goal is to get everything working and reliable.Jim and Sue
