Hi this is Chris, Last week I had the bedroom slide on my 320 MKs pull out the wires that power the over-bed lights. This is a common issue apparently. I sorted out the wiring on that, but when checking the voltage I noted the following:
1) no lights on have 12 V nominal although battery voltage is 13.9 V
2) one over-bed light 8.7 V
3) 2 over bed lights 8.5 V
4) only the outside light under the slide 5.4V
5) tank heater switch on 0.0 V
The indications are consistent with and without shore power. I checked the ground and have good ground at the lights and control panel by the door
I am concerned I have a hard ground somewhere when I turn on the tank heater...is there a fuse or control panel to disconnect?
Any advice on isolating?
