No Power to fuse block 7010

[Keltic]

Hi, I suddenly lost power to the fuse panel that controls the heater, beacon, wipers etc, anyone know where to look first? Thanks, FMK

Did you check the fuse box?

No power to the fuse box

Just a guess, but there should be a fuseable link near the battery that feeds the fuse box.
Start at the battery and chase all of the positive side wires. There will be a large wire that runs to the starter, I’d bet there is another 10 gauge wire or wires continuing on to the cab area from the starter. Those should be fuse protected somehow.

Makes sense, thanks, I'll have a look!

There are 2 60A slow burn fuses in the engine harness on the right side just above and behind the starter. If I remember correctly one of them supplies power to the cabin power relay that powers the fuse block for the lights, hvac, ect.

Thank you, just what I was looking for!!

Seems I have power, but no ground in the cab, is there a special ground between the cab and chassis?

Did you ever find if there was a ground between cab and chassis?
