Seems like the wrong approach to me. Send him to the store and buy an cheap digital voltmeter. Measure the voltage at the refer with the comperssor running, no shore power and battery partially discharged. If it meets mfg specs then wiring is OK. Next repeat but measure at the battery terminals to make sure batteries are OK. Better yet have the batteries load tested. What did he find?
Otherwise measure the distance for new wires and use a wiring calculator to find the wire ga needed for the new wires. And go directly from the refer to the battery with a fuse unless there is some really heavy wire nearby that can be used.

I can gurantee that the Norcold 12 volt supply line is NOT 10 gauge. Since the 12 volt for your year Model Norcold is just for operating the refer electronic controls, odds are the supply gauge is 16/14 gauge. But, it will NOT be larger than 14 gauge. Doug

They look like factory circuit numbers. Circuit 150 is a factory ground. Circuit 603 is some kind of lamps circuit(I haven't figured out the GLY abbreviation).

I wondered if GLY could be Galley.

Sounds like a good possibility.

Doug That's the bottom line - Bad install on Dad's refer. Correct the wiring and move on, sure he could go back to the installer...
Makes one what else is not correct, insulation, air clearance, support, etc.
