Left the rig for a few days and came back and the 12v fridge was off and all of our food was ruined 
. Pulled out fridge and one of the 40A fuses was burnt. I was able to get another fuse in there to get up and running. Of course the warranty is up and the extended warranty is a pain with a $100 deductible so I ordered the PCB from Lippert and I am going to change it myself (quicker and only $162). Since it is direct wired, where do I shut off the power to disconnect the board? Do I need to shut off the power since it is only 12V?
