low voltage to some locations
First time poster here. I recently acquired a '71 ambassador in near original condition but had been sitting in the weeds for maybe 10yrs? PO stocked it well with mothballs so no obvious rodent issues but there is one particular electrical gremlin I can't seem to sort.
When connected to shore only (waiting on batteries to ship), all galley lights, bathroom light and door light work. A/C and vent fans also work.
However, neither the oven light, or sink light work. The oven light only dimly glows which clued me into a voltage issue. Sure enough, the oven light socket metered at ~1.5V and the sink light was the same. I also tested the breakaway supply wire and it too only measured 1.5V.
Does anyone have any clues about what might be going on here? If it was a missing battery issue I would suspect all lights/appliances would have this issue, not just a couple.
