Norcold compressor fridge troubles
Hello folks, this is my first post :). I'm converting a truck, and I lucked into (I thought) a Norcold 12/120 for $50. Like an idjit, I hooked it up to a 200ah AGM battery and left it overnight....

I did not know that Norcold made a refer with a compressor. I thought they were all absorption heat cycle. What model # is it? I'd plug it into AC and give it 8 hours to cool.
Both Norcold (At AmericanRV) AND Dometic (Company web page)
Make Danfoss jobs
To the O/P.. sounds like the compressor is siezed, so the motor never came off start and thus current draw was very high..
HOW TO CONFIRM.
Get a good DC-Ammeter that can do 10-20 amps and either put it in line (Remove fuse, add jumper leads do not forget to include the fuse so that it is :terminal---fust--Meter---other terminal
Or use a clamp on DC ammeter like the Crafstman 82369 (Which is beside me as I type). If it shows high current (more than six amps) for more than 10 seconds, you have a siezed compressor.
I have never had a Sawafugi compressor seize but I suppose they could, They fail internally and continue to run but do not cool. The other failure mode is an open winding and you do not hear it doing anything. Either failure mode is moot since the compressors are not replaceable. Bottom line is, if you get 23VAC to the compressor and the box is not cooling, the compressor is bad.
