Trying to get my 84 z-28 back on the road, and I think I missed a ground somewhere....when I put the a turn signal or 4 way on the parking lights flash in sync, and when I turn the parking lights on the turn signals stay on...including the ones in the dash...also the side markers seem really week....checked all the grounds I could find and the ohm out good....what am I missing???

 

Sounds like you have bad bulbs.

 

All replaced and all confermed lighting up
