Converter will not charge batteries
Hello, I need some advice. I purchased an old TC and on my first trip I realised the batteries were not charging when hooked up to shore power. My previous TC's converter always hummed when it was p...

Wiring looks good from here.
Could be a difference in function, mine is 10 years old but I can disconnect battery and converter does power circuit board. However, in normal use you want battery 'on' supplying power, converter just recharges it and shouldn't be used to power loads directly or without battery. My disconnect is between battery and converter so turning it off isolates camper from battery, (but it also wont receive a charge). But again battery should be 'on' regardless of converter on/off or shore power.
my 2 cents- with battery on and camper AC connected, converter on- multimeter should show converter voltage at both battery & converter positive lugs.
With converter turned off (breaker) you should see battery voltage at both terminals.
If converter voltage shows at battery board terminal, Id pull the battery cable lead from converter at battery and check voltage there-should see converter voltage from converter on cable. Pulling battery lead at board terminal should see battery voltage on cable.
For some reason (short of converter malfunction) with what so far has been related- makes me think some how cable from battery is one way, only sending battery power to converter but power cant travel back. I cant see how that's possible unless whatever was added as disconnect has that function?
