61 D100 Headlight Fuse

[mousecat]

Anyone know what size the fuse should be? Fried a 5, and and 7.5. Took a 5 amp out that was shot, but don't know what size it should be? Don't want to fry anything else so I figured I'd ask.
Thanks in advance!

Headlights would be one of the highest amp rated fuses in the whole truck. In fact didn't they start using relays or fusible links in place of headlight fuses?

Only thing I know is that the fuse in set into the switch is the only fuse in the truck! No fuse box, no relays no nothing. Just the one single fuse in the switch. Turned them on, with one light hooked up, plugged in the second light and the fuse popped. Popped in a 7.5, and two lights worked. Switched on the high beams and blew that one as well?

Looks like a 10A

Thanks Kurt!!

I printed that diagram out and was using it to track down what was missing, but didn't even see the 10A!!! Maybe I should drink less beer while working on the truck???

Naw!

Thanks again!

See if you can still get the circuit breakers that pop into fuse slot for the glass fuse style. Or modify circuit to allow a circuit breaker.

FYI, I was thinking 10 amp fuse at first but the L10-A is the wire number in the chart above the schematics. The L10-A is a brown # 12 awg wire going to the rear tail lights from the switch.

The incoming wire from the alternator to the head light switch is A-5, which is a Black # 10 awg wire. A # 10 awg wire is good for 30 amps. It looks like it is the main wire feeding the head light switch and ignition switch.

That sounds better. I was bored and looked on autozone. Each headlight is about 4 amps.

Seems as though I have a new problem now? Yesterday everything was fine, got all the front lights working, then started tracing down the back lights. Called it a night, thanks to all the beer, well now today go back out and I have no power?
All of a sudden, nothing works? WTH??

Baby steps.... And yet another step backwards?
