Ok, so here is where I am at now. Like I stated earlier I had it plugged in to shore power running on LP. It ran fine for two days. Tuesday night I shut everything down, un-plugged from shore power and started it back up on 12 volt only. Wed morning the check light was on. Wed evening I came home and started un-plugging wires off the circuit board. I checked the power coming from the battery, it was the same as the reading at the battery(12.63). Plugged all wires back into board, started up fridge on DC only and it has been running ever since with no problem! It's now Saturday morning. I checked the battery voltage, 12.5.
Do/did I have a slight bad connection to the board on a wire? Maybe a cracked trace that is now closed because of all my pulling on the wires/board on Wed?
I just gotta laugh
