Alternator what is everyone using our po put a Balmar 712-80 and after eating 2 belts in 10 minutes and getting toed back to port I put a tester on it and it's junk we use a lot of power I have a c-pap and can't live without our Keurig I also figured out that the problems with the tack was because the alternator was dying I've tried to educate myself but still feel I need some help I want to put a big enough alternator that I don't have to worry about power we have four house batteries and a starter battery
