HWH Issue

[al perna]

Hello WaGu ,

Have working on a issue the past few days with the HWH . We have no power to the Jack Panel in the coach . Here is what we know so far P1d4 fuse in the coach driver side panel blows when the 15amp fuse is inserted in the HWH bat fuse spot . So with the 3 blue fuses removed in the HWH box the 15amp fuse to the coach will not blow , but as soon as the bat 15amp fuse is inserted , the 15amp coach fuses blows.

So now that we know we have a HWH box issue , the question is , can we purchase 1 board , and which one is it , or do we need to send out the entire box to HWH for repair ?

Than you in advance for your expert advise
