ProMariner charger trips shore power breaker

[shawnpb]

My 2008 R25 has a Pro Sport 20 Promariner charger that is tripping my main breakers. My AC panel has a separate charger, 15amp breaker, that was tripping off occasionally, but now trips as soon as it's reset and now trips my main 20Amp shore power breaker as well. I disconnected the 3 charging outputs, flipped the breaker on and no change, still trips the main breaker. I'm assuming the Promariner charger has failed and need replacement, but curious if anyone has had a similar issue. Thanks for any feedback

Hi shawn,

Unfortunately I have not seen this exact issue first hand, but definitely agree that the charger is most likely suspect and should be diagnosed for issues. However, I would also recommend checking the incoming shore power for issues as well. You didn't mention if the shore power worked without issues if the charger is either not turned on or disconnected. Just make sure to isolate the charger to make sure it is the only cause of the issues you are experiencing. Hope this helps.

Thanks,

Ralf
