289/v8 s30 conversion. My headlights do not turn on when combo switch turned on. All rear light work great.
I checked combo switch terminal box with the 4 wires, for power at w/r wire, when switch turned on is ok 12 v. Checked red wire shows that it is a ground no voltage should be correct.
I read where headlight circuit gives power to headlights via a ground through the dimmer switch. Headlights turn on when I feed 12v power to them with my power probe so i think the circuit is fine.
Can anyone tell be how I can get a ground to the headlight circuit without a dimmer switch, iow, is there a terminal on the combo switch area (i.e. c9 plug) that I can run a ground wire to to allow a ground for the headlights to work.
I get full voltage at the combo terminal box with the w/r and r and 2 gr, but 11.4 at teh circuit for the parking lights ( prolly seperate issue just needs terminal cleaning )
Tks
