1986 Ford F-150Hello, My vehicle has no power to interior lights, exterior lights, and when I attempt to start the truck it won’t even turn over? The truck has a brand new battery, alternator, key ignition switch and starter that is just one year old! The truck will turn over when I cross the negative and positive terminals on the solenoid but it still will not start? Please help me, Thank You…


RESPONSE

Looking at the wiring diagram below I see the Battery positive connection to the headlight switch is separate from the battery positive to the Ignition switch. I would think it is still a connection issue at the battery and a bad fuse link. Make sure there is no corrosion and if you need to use a multi-meter to test your connections.
