So here is a summary of events. Related to my TM electrical problems on this trip.

I have a 150 AMP lithium battery. I have tested it and it is really a 100 AMP battery but I bought it from china, not here on the forum. I have several days to try to fix a problem here in MT before I head back to MI.

1. I had 2 30 amp fuses on my 12 volt board burn out.

First, here is a link to the web page of my Converter which tells about the 2 30 Amp Fuses that blew: Reverse battery protection fuses.

I replaced the two 30 AMP fuses on my 12 volt panel and have tested a number of different electrical configurations and they have not blown. They now stable. I have not been able to duplicate them burning out.

2. I blow my brothers 110 GFI in his garage outlets each time I have all 120 volt circuits on. When I have main, microwave and airconditioner circuits on there seems to be no problem.

3. I bypass a GFI outlet and turn on all 110 circuits and there is no problem with the 110 circuits on my TM panel blowing.

4. I turned the 80 AMP breaker off, disconnecting the battery to the converter, converter works: it is putting out 14.5 volts to my 12 volt panel. All 12 volt lights, fans, etc work. There is 14.5 volts going to both the 12 volt system and the battery. With 80 circuit breaker to the battery off/disconnected the converter continues to work.

5. I turned the 80 amp breaker (which is in between the positive wire between the battery and converter). BMS system on battery registers charging, Battery monitoring system you recomened recognizes charging. I switched to 13.2 volt output on my converter and it was putting out 57 AMPS (my charger as you can see is a 55 AM charger). .

6. After about 90 seconds the 80 AMP fuse blew. (This is what was happening. This is now a consistent problem.

7. I put a regular charger at 10 Amps to charge my lithium batter for a short time. Neither the battery BMS or my installed Battery monitoring system are registering a charge.

ANY SUGGESTIONS?

Is my breaker bad?

Is my batter bad? (It holds a charge and I used it without a full charge before the BMS shut it down.

Is my converter bad?
