I have been working on my Norcold 1200 again and have noticed that the unit will power up and operate when only connecting the 12 volt (+) supply to the rear control board connector labeled "12V". The connector labeled GND can be disconnected totally. Obviously there refrigerator is somehow already grounded somewhere, but I am wondering if this is a problem or is normal??
I think you all missed the question "Is this a problem or is it normal?".
No it is not normal which you can gather from all the responses trying to help you figure out how it's possible. But is it a problem? Probably not but I guess that's where you have to define your meaning of the word problem. Should the actual ground be fixed or attached? Absolutely.
Sounds to me like it is normal to have grounded copper piping. The OP has the ground wire disconnected and intends to put it back so also no problem that I can see.
