Troubleshooting the Stone

Yesterday after work, I went out to the Rolling Stone with Lisa to help her try to diagnose the problem with the electrical circuit feeding the 'coach' or 'hotel' power on the RV. (That's the interior lights aft of the front seats, the water pump, fans, and most importantly the DC accessory outlet that powers my CPAP.) I held tools and sat inside the RV looking at a light we'd turned on, calling out whether it was lit or not, while Lisa tested things.

Lisa's initial theory was that the ground lead (line from the negative terminal of the battery to the frame of the vehicle) was loose or frayed. However, the screws were tight and wiggling the line did nothing, so she tried a different theory, this time with what looks like success.

Had we worked this out while I was on the road, and had we realized that just lubricating the hood latch would have made it open without assistance, I might have been able to work around this problem by just tapping on the balky breaker when I needed power. However, I survived (albeit with some accumulated fatigue from insufficient restful sleep), and for less than $20 in parts, we should be good to go once the replacement arrives.
