I have no headlights,taillights,nothing but turn signals.
That's what I did last week but so far he hasn't touched it. I talked to an old friend of mine that is retired and he told me to start with the switch as well,so I might go get it and try that if the shop doesn't get started soon.Have lost several circuits, this is not a diagnosable by internet problem. Find a mechanic that has electrical troubleshooting skills is your best bet.
100% agreement. The male/female spade connections and the block were not well protected against moisture. Additionally , added circuits like dash mounted fans, extra running lights etc would overtax the connection and loosen the female spade with excessive heat.One problem those IH's had was corrosion at the main bulkhead connection on the engine
side of the firewall.
No power at the switchIs there power at the headlight switch? I would expect two power supply wires one for headlights and one for park lights.
Do you know if the fuse blocks are still available from International? If not would it be possible to retrofit from a newer model? This is a really nice old truck otherwise and I need to get some lights on it. We did get blinkers and brake lights but no fire at the headlight switch.100% agreement.

ALSO recommend looking closely at the headlight switch itself. Those old ones supported 100% of the load, no relays. It may be a burned/loose connector assembly as well. I seem to recall that same switch and circuit used up till 90-91? Somewhere in there, when they switched to low current switches with load carrying relays. Good luck.
I could not find any fire at the switch. I was wondering if I could run a hot wire straight to the switch from the mattery and put an inline breaker in it?100% agreement.

I guess I need to start proof reading, that was supposed to say BATTERY not mattery.I could not find any fire at the switch. I was wondering if I could run a hot wire straight to the switch from the mattery and put an inline breaker in it?
