I opened up the converter panel and noticed the breaker for the converter was tripped. I reset the breaker and it popped immediately with a small puff of smoke from the fan. All 12v and 110v items work, except for the battery charging. Thoughts anyone??
I'd be looking at the DC circuit wire that runs from the charge controller at the power distribution center up to the junction box at the front of the trailer.
Do you have DC power when not connected to shore power? That would determine if the battery is connected to the DC distribution system in the trailer.
If yes, I'd check the junction box for problems. Then I'd look for any obvious problems on the wires running from the junction box to the power distribution center. If I didn't find anything there, I'd pull out the power distribution panel and start looking for problems there: loose screws, bad wire nuts, shorts, etc.
