Magnetek 7300 Sean 6-19-15  
I've been having some electrical issues with my Minnie winnie 427p. in trying to find the issue Ive gone thru the magnetek 7300 with volt meter and found two anomalies. 1. there is some 12v feeding back thru the output line going to the slide outs (post 15amp fuse) possibly from the rv's motor battery? and second, when I pull the 2, 30 amp main fuses on top of the magnetek 7300 there is 12v on both sides of the fuse holder. is this normal or is the converter faulty?

1st the second point. If the RV is plugged in the converter will provide 12 volt to one side of that fuse and the battery to the other. 100% correct operation.

2nd the slide back feed, some RV's have the slides powered by direct battery power, Some are Controled by a board. Direct battery power one of the control switches will be powered from the converter and one from the converter. If the wiring or the remote switch down at the battery box is bad a back feed is easily possible. The system with the control board is often cross wired from both sources and will back feed.
