Quoted from FLASHBALL:

Checked all the fuses on the Aux driver board and they all test good with continuity.

Replace F-7. Just because!

Quoted from FLASHBALL:

No change after replacing F7. Thinking about trying another bridge rectifier even though the 4 diodes inside this one test good both ways.

Pull the board and snap a good pic of the back.

The back looks good, no burnt traces/cracked header pins.

The pic I added is your board, since everything on the back of the board looks good I think the trace on the top of the board is burnt off or you have a cold solder joint at the red arrow. Give the top side a good look see.

Quoted from FLASHBALL:

Not sure why solder wasnt wanting to flow through from the other side.

When you solder something like this with a large heatsink, Always heat the lead with a wetted iron and not the trace. Wait for a bit (depends on the part) then add solder to the lead add it will flow thru the board and onto the top trace and then it will fill up the hole and spill out onto the bottom trace.

I was afraid of burning up the trace/solder pad

Not if you just heat the lead of the bridge. These type of bridge will absorb quite a bit of heat before its ready for solder.
