Progressive Dynamics Inc Converter blowing battery fuse

2012/2013 Jayco Jay Flight owners, what size fuse do you have from your charger to your battery post?? The holder should be right off of the battery post. I've already blew 3 30 amp fuses and the 4th ...

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
