With a good converter/charger, like what you got, it shouldn't be able to overcharge anything, should it? I wouldn't think you would need to use that battery minder. I've got an Iota 55 amp unit and that's all I use all the long MN winters for storage. I don't think it's been a problem for me.

the 30a outlet was either wired wrong or SHORTED.
the outlet had 120v on the ground and hot/blade - which gave me 240 volts.

i have an analog meter plugged into one of my 120v outlets in the coach, it was PEGGED after i plugged the coach into shore power & my Volt/Ohm meter showed 240v across the 120v outlets.

all my 120v outlets were recv'ing 240v....the converter recv'd 240v instead of 120v. i would have expected a breaker to trip or some (possible) internal over voltage protection to have "tripped" inside my converter/charger - but i only see fuses for improper battery wiring (not improper ac voltage).

MY MISTAKE -

i only checked the two BLADES on the outlet and had 126v, had i checked the ground i would have seen the ground also had 120v across it too.

a surge protector would have saved me from this ground fault/short (lesson learned). I consider myself lucky that i didnt burn anything else up (electrically or by fire).
