Doesn't really where the feed is from
; rather why it's not going to
Not having seen this fuse block, I wouldn't know what to look at specifically, but I'd check three things:
- Positive bus - check for power on the currently-powered side of the fuses - the common bus should have +~12V
- Ground - check for postive power on the non-powered side against a known-good ground
- Master cutoff - look near/on the block for a master fuse or circuit breaker (manual or auto/thermal reset)
Chances are you have a bad connection on the positive bus or the common ground.
If there's a master cutoff, it could be a thermal-reset circuit breaker on the positive feed from the batteries. Disconnect the batteries and wait an hour to see if the breaker resets. Or see if there's a reset button on the breaker.
