In need of some help. I have an inherited Norcold 12/110 volt refrigeration unit on my boat. The 12 volt side of the system no longer works while the 110 volt still functions just fine. Any suggestions as to what to look for in determining the source of the problem. As a clue, one day my master 110 breaker was tripped and the battery charger was not working for about 3 days and my batteries were badly depleted to the point they would not turn over the engine. Could the refrigeration unit be drawing down the batteries through a short of some sort?
Thanks

Thanks for the replies. By chance I was measuring space for a replacement unit and saw a splice on the 12 volt side. Jiggeled it a bit, turned off the 110 master breaker and low and behold the fridge kept running on 12 volt power. Will redo splice with solder and heat shrink. Must have drawn down the batteries while not able to power up the fridge. I can't say I like the unit all that well and will replace it in the spring and sell off the old unit. which is rather noisy and not all that well designed. Had to fix a leak and had to add a nipple to ad outdated freon which I had a source for. Also there is no fan to cool the unit Thanks again.
