It's not the reverse polarity fuses. It the positive line fuse coming off of the battery post.
It doesn't blow all the time, but it has blown 4 times now. It's only rated for 30 amps and the battery is dead. If the PDI does charge at it's full current output of 45 amps, that's what the problem is but both Jaycos I've had came with 30 amp battery post fuses.
Thanks
you need at least 50A, preferrably a 60A fuse to the battery. The PD can easily give you the full 45A to the battery, and that will blow the 30A fuse. Also make sure the wiring between the converter and battery is rated for 50A,( #8 wire at a minimum)
