12v fuse board

Hi,
New to the forum hello all glad to be here.
I'll get right to the problem.
I have a fleetwood ralley year 2000 . I replaced the bottom of the magnitek 6300 series converter with a WFCO WF-8935-MBA 35 Amp Main Board Assembly.

The reason I switched is because the Mag was not charging batteries and 5 of the 8 fuses had 17v on them. Now I installed the wfco and now 5 of the 8 have .06 v which is nothing. the three that work have proper 13.6v Can't figure this out. This is when pluged into 30amp service.
  • New to RVing . Where would I look for the reverse polarity fuses.? Near the batteries?
  • Check to see if one of the two reverse polarity fuses is blown. Maybe some of the utility fuses route through one and the rest through the other. Just thinking out loud.
