[C320-list] Refrigeration Diagnostics Assistance

[Ken McCrimmon]

Hi Troy
Finally made it back to the boat today
One battery is showing 13.58 on the multimeter and the other is at 13.53

I replaced the 15 amp fuse on the compressor as somebody else suggeted

Tried starting the fridge on either battery

Nothing.  No sound from the compressor and no cold in the fridge

What should i try next

Couple of easy items folks sorta glossed over because many folks who post
here already kinda know the basics, but just in case you aren’t tracking on
some simple things to look at.

Your fridge runs off the batteries, so if the batteries have a good charge.
Then your problem is on the DC side of things.   If your batteries aren’t
 charged then you most likely have an AC charging problem.  Can you check
battery voltages and tell us what you have on both batteries?   Does your
fridge not come on when either battery is selected?   These would be really
helpful with regard to steering you down a good path.

Leaving the fridge running while away for longer than your batteries will
last is always a gamble if your shore power isn’t solid or if folks at the
Marina have a habit of unplugging you or tripping your shore power breaker…

Let us know what you have going on with the batteries.
