Good Morning:

I have a 88 Ford F250 and my headlights won't turn on. I've replaced the headlight switch, bulbs, cleaned the ground wires, replaced the solenoid, and the fuses are good. The side lights turn on and the brake lights work on.

There are two 16 gauge fuseable circuits that connect to the solenoid switch. The auto store stated it could be that the fuseable circuits are blown? Do you have any ideas?

Welcome to the forum, the two voltage circuits to the headlamp switch, tan wire with white tracer is a fused circuit. Black wire with white tracer goes to fusible link, hot all the time. Check voltage at those wires. The fusible link should be located underhood, passenger side wheel-well at starter relay. Thanks for the donation.
