No power to part of the interior fuse box

I am assuming when you say there is no power to part of the fuse block that you have fuses that have no power to either side of the fuse?

Here is how we need to test them to confirm this:

If this is the case that you have fuses that do not have power at all then we need to check to make sure there is good connection of the B+ wire coming into the panel.

If that is okay then I suspect you have an issue with just the fuse panel circuit board.

Basically there is no other connection between the power supply of the fuse box and the actual fuses other then the circuit board of the fuse box.

So if you are not getting power to them, I suspect the fuse box is the issue.

Please let me know if I am understanding this correctly and we can go from there. Thanks
