Ok to install panel for fridge with suspect converter problem
My fridge (Norco 682) has not worked in my 1991 motor home since I bought it 4 months ago. I diagnosed the problem to be a bad panel and promptly ordered one. Since then, I have had three different 12v light fixtures blow bulbs, indicating a possible problem with the converter (Magnetec 6345A). My question is, should I wait to install the fridge panel until I have a new converter, or can I install it now? I worry about blowing the panel with the old converter.
Thanks in advance.

Have you tested the voltage of the converter to see if it's the problem?
Check for both AC and DC voltages on the DC line when you check it.
I think I'd wait to install the board until you find out if there's a problem with the converter or wiring in the RV.

... and don’t overlook your voltage regulator if it is connected to you house battery bank. 27+ years is plenty of time for Knuckles McGirk to have “re-wired” it.

Thanks for the quick reply! I get 114.6 on AC and 13.6 on DC. I am confused "check both ac and dc on dc line"?

Judging from the tape on the wires, he rewired it. What might the voltage regulator look like?
Thanks for the information.

Sometimes when the rectifier unit in the converter/charger is going bad, it'll put AC (alternating current) on the DC (direct current) side of the charger and that'll cause problems for some DC electronic components. Set your multimeter to AC and see if there's any AC on the DC line. There shouldn't be more than a tiny bit.

I get 28.3 AC volts on the DC line. I'll bet that would blow the 12v dc bulbs. Thanks! Sounds like a PD4645V is called for. I really appreciate you guys being here! I learn so much!

Bummer.
Sounds like it's time for a new one.

Not too bad
Well, it's not such a bummer. At least I know the problem, and I saved my investment on the fridge panel.

Not that its relevant at this point since it appears you found the offending electroniker, your voltage regulator is most likely built into your alternator. I just mentioned it as an outside chance issue. ‘91 is new enough to have solid state internal regulators.
