I have a 1983 Cutlass Supreme with a 3.8 L V6. When I press the gas, my headlights dim bad, why is this?

Question

I have replaced the alternator, alternator belt, and battery. I also have had the alternator checked by a mechanic, and it is charging just fine. Where do I go from here to diagnose my problem? What do I check now?

Answer 1

You have a bad ground wire between the engine and the chassis.

Answer 2

Check your motor mounts and the ground cable. If a mount is broke, the motor will torque one direction and lift off of the mount. If the motor moves too much, it can tug on the ground wire and either loosen it or break it inside the insulation.

I've seen a cracked bracket flex every time the gas was hit causing a loose belt.

Or a slipping pulley. There's a nut on the front of some of the pulleys that holds them on.

Answer 3

Check the:

Headlights
Headlight wiring
