I have a 1985 f350, 6.9 diesel – my problem is the headlights go off and on intermittently like a bad relay, but i can’t find a seperate relay for headlights. Problem is worse on high beam?

This being a 1985 it most likely does not have a relay like the newer vehicles. The problem is most likley a loose, dirty or bad Ground wire. This was a common issue on the older trucks.
