I have a 1966
, and the electrical system seems to be acting a bit wonky.
Specifically, the issue I am seeing is that the overhead lights in the trailer, which according to the manual (attached) are on a 12V
DC circuit, only turn on intermittently when the trailer is plugged in to 110V shore power. Everything else appears to be working fine: all of the 110V AC outlets in the trailer appear to be working well when plugged into shore power; and when switching from shore power to battery power, all of the lights in the trailer work consistently. The issue only seems to affect the lights when plugged into shore power. They mostly will not turn on, but sometimes I can get them to turn on if I switch from AC to battery power rapidly several times by toggling the switch on the low voltage panel. Sometimes they will turn on on their own, without me toggling the panel, but then sometime later will turn off on their own.
I have attached some screenshots of the wiring diagrams from the owner’s manual. All of the wiring appears to be original, and corresponds to what is depicted in these diagrams.
I was wondering if anyone has any suggestions for what component of the electrical system might be failing? Also, is it dangerous to leave the trailer plugged into shore power given the above failures?
I would appreciate any insight anyone can offer on this. Thank you for your time and attention.
