I’ll try to make this as short as I can, got to camper and had zero power, 12v bought last year flat dead. I check cables going to battery and get nada. So I think converter has went bad. My camper has shore power wired straight to pole on a 30amp breaker that runs inside and hits another 30/20 breaker I flip it off and back on and it sparks and my converter kicks on but cuts back off but that breaker kept making popping sounds so I cut it back off and also went ahead and just killed my main at pole. I’m going ahead and ordering a converter but does that breaker inside sound like it’s going bad? Or what’s it’s issue.
