Possible Convertor Issue??

[novaplum]

I have a 2011 330 RLTS ,I have had a blown fuse issue recently.I replaced the30amp fuse in the fuse holder near battery hook up and will remain ok when used by the battery itself but when I hook up to the main power line not right away but at some point the fuse will blow.Im wondering if there is some possible short with the power convertor.Any hints of what to look for would be appreciated

Check all wire terminations and make sure they are clean and tight. ( battery, wires on converter )Check where the battery negative side terminates to the frame ground lug as well

I'm assuming that the battery is in good condition and does not have a bad cell, or that you are not draining it all the way down, then trying to recharge and blowing the fuse because it's drawing more than 30 amps ( my 30.5 has a 45 amp charger)

I'm also assuming you have clean A/C power.
