Low DC Voltage at Fridge and Thermostat

[jrjablonski]

Hi, I have a 2010 Thor Hurricane 30Q and have Low Voltage at Fridge and Thermostat (less than 7 VDC). I've checked all DC Fuses at the Converter/Charger and measure more than 12 VDC at all fuses. What should I check next to Diagnose Low DC Voltage problem? Converter/Charger is 30 Amp and original.

I would type your exact thread title into Google and give that a try... Youtube videos are very instructive. I won't have to wait for a reply.

I'd do this because it broadens my chances. The fridge, thermostat, converter, fuse panel are not Thor products. They are common in all motorhomes, worldwide.
A worldwide response.
At 11 or 12 years old the only thing Thor on your motorhome is the wiring schematic and build parts placement.

Well, one of those fuses you are measuring 12 VDC + at is for your Appliances. Sounds like you have a poor connection someplace between the DC distribution panel (fuses) and the appliances. Time to wire trace and check all connections.

you have a bad connection in the 12-volt control circuit. Should be easy to find starting at the fridge.
