On backside of fridge is a terminal block where 12V DC +/- wires connect from your DC Dist Panel Fused Circuit
GOT 12V DC +/- there?
**Yes, Terminal Block has 13-14 DC vlts.
12V DC + goes from terminal block to stack thermal fuse then to circuit board at J4 terminal
Got 12V DC + at J4?
**No DC at J4.
(Thermal Fuse is 'resettable'....button in middle/push in---if tripped NO DC)
**I could not find a 'thermal' fuse on the rear board. However, there are two smaller white wires coming from a plug where the schemetic says the 'thermistor' is. I chased and lost them between the rear wall and tube steel. I checked the display board and couldn't see that they terminated there. (I'm not familiar with a thermistor, but I did find two devices on the display board labeled SW3 and SW4 which resembled some kind of switch, and pressed each one with no reactions.
12V DC + at J4 (J10 DC -)
**NO DC
3A Fuse....
**Good
Got 12V DC both sides of that fuse?
**YES
J2 is 12V DC + to interior light switch and the climate control heater switch
**No current at J2.
