Hello I have a 1985 gmc c2500 v8 350 I recently had my 700r4 rebuilt it crapped out . Then I fired it up and heard tapping . Under valve cover . Long story short had to replace cam Tapp lifters and wile I was doing that noticed someone pit 305 heads on it replaced with 350s broke in went well tuned carb up and when I went to drive her for the first time after fixing all of this I noticed I did not have headlights nor do I have marker lights . Broke out the prob and multi meter. All grounds are comming out good . Fusible link are showing up hot . Checked headlights with my probe and headlights light up so they do work got under the dash looked at the switch red wire is always hot as should be all fuses look good. But with it all looking good I'm not sure wear to go to now . How many grounds are their for the lights on my truck I got 3 up front off of wiring harness for headlights . I got one on pass head to frame battery to frame and I got one under the dash on driver side by the switch did I miss any? I'm thinking switch because all the wires.and grounds check out good. Not sure what elts it could be . Brake lights work reverse work blinkers work no headlights high or low and markers. What u guys think im lost on this one
