12V circuit only works on shore power or generator

I received and installed the upgraded converter/power supply that was a swap-out for my orignal BM Manufacturing 6345 with a 6345RU

The unit I bought came with a new DC distribution panel as well as the converter power supply. I know there are better options but it took me about 45 minutes to pull and replace.

It works beautifully and my problems appear to be resolved. As someone mentioned, they thought that the charging portion was not working. I believe this to be the case because the battery reads about 1 volt higher than it did with the old unit. So instead of 12.7 it was reading about 13.65 when I turned of the generator.

Thank you for your help. I'm a happy camper.

Hey, if your 12 vdc appliances are working when you are plugged into shoreline power or when running the generator then you charger/converter is working just fine. It is not the problem. Are you sure your house battery master ON/OFF switch is in the ON position.

I replaced the single stage converter with a modern 3 stage converter in my old RV, not as old as yours, and I also replaced the #8 wire from the converter to the battery with #4. If that wire in your RV is long it is probably worth the effort since the voltage drop in the old smaller wire may be fairly high and may produce too much heat when charging at a high rate.
