1986 GT Fiero. I purchased this about a year ago and had not driven much at night. Figured I needed new headlights. I replaced them and even put in HID lights but the light is still dim. I can onlt see a foot in front of the car.

Anyone else dealt with this or have some suggestions of where I can start?

If I missed a previous discussion....

Check the grounds... There is a write up about adding a new ground on to the engine to fix several electrical gremlins...

Edit: Check obvious things like alternator output. Use a multi meter, the gauge isn't all that accurate. it should be about 14v with the car running.

I also agree tshark, the wiring is old, check the ohm readings, dim lights anywhere means there is high resistance somewhere in the circuit... Ohm out the wire from the bulb back to the various other locations... if you find high resistance, look for corrosion on terminals first before going crazy looking through the harness; simple corrosion on terminals is usually what causes high resistance.

Could be voltage regulator.my alternator is about to crap out on me,poof!just like that.take your car to advance auto or something,they can put their computer on ur battery and do a load test like on my duke or just start ur car and pull the negative cable ans see what happens,hope this helps
