I'm not sure the only thing I came up with is a back feed from the 12vdc fuze panel

You cannot have 12 volts to the fridge if the fuse is blown. Sounds like you are confusing two different circuits.

No I was not confusing what circuit I was checking. Considering I checked the 12 supply at the fridge. I was sharing to see if anyone else had this or not. Thanks for your reply

OK, 12 volt DC, is low voltage and is not regulated like high voltage AC or DC. It is very possible that there is some "feed back" in the system somewhere. Now, the feed back may mean that there is a possible problem in the system elsewhere. Remember, the only thing in this World that is fact, is Death.

Measure the DC at the terminal on backside of fridge


THEN pull the FUSE from DC Dist Panel for the fridge


Measure the DC at the terminal on backside of fridge AGAIN


Still got 12V DC......keep pulling FUSES one at a time until you ID the circuit that is giving you DC on that fridge DC wiring

I believe that the residual voltage is comming from the LED indicator on the fuse panel itself. The led is on only if the circuit is open. I should have checked that first but I didn't die to having 12vdc fo ground at the terminal block. The fridge is working now live and learn. Thanks again for the help, the coach is new to me and did not realize it had open circuit indicator led. Keep an open mind and you can learn every day.
