Magnum mms series help

[Jim161]

Fault AC overld: this is what's showing on the inside display with shore power.
Fault bridge: with shore power off.
I have reset the magnum mms several times with same results any ideas?

You might want to call Magnum and speak with their tech department. I've heard that their circuit board has had issues and they are replacing them.

Talked with them this morning about this issue. They talked me through a hard reset with no luck. Waiting on call from a noble tech right now.
