Question about 1985 Pontiac Firebird

1 Answer

After replacing alternator, battery, headlights still do not work

Recently, on a long car trip with my 85 Firebird, both my headlights suddenly went out at the same time. Soon after pulling over, I realized my alternator was not working and that the battery had been leaking acid. I'm not sure what caused what to malfunction, but I now have a brand new alternator AND battery, but my headlights still will not go on. All interior lights work, parking lights, and signals, just not the headlights. Does anyone know if it is the switch or did I just burn the headlights out? Thanks for any advice!!!

If the battery was leaking acid from the filler caps on the battery it may have been caused by the alternator over charging (faulty voltage regulator) hence blow your light bulbs or blown the fuse check for blown fuses first,if they are OK you may have to replace the bulbs .....hope this helps....cheers

Battery light came on, had it tested, said Alternator was bad, replaced that with a brand new one, still got the red battery light. Replaced the battery w/a top quality one, all was good until about 10...


I wouldn't suspect the alternator. First I would check the battery connections, ensure they are tight. Check and make sure they are clean, no green fur or white corrosion. If any exists, loosen off the cables and clean. Quite often alternators are mis-daignosed to simply bad, loose or corroded battery terminals. They build up with excess resistence in the form of corrosion, and can't accept any voltage produced from the alternator. Second check the ground cable from the battery to the engine, and to the frame (or body), make sure they are tight and clean. If there is still an issue i would suspect a wiring problem to the alternator that is inhibiting the regulator to produce voltage.

It could be that you alternator is not working as it should. Clean the connections at the battery before proceeding. After reconnecting the battery cables, check the voltage at the battery with the engine running. It should read 13.5-16 Volts DC. Any less and the alternator is weak and needs replacing.

Air Bag Light, Brake Light, & ABS Light came on in the dashboard.


Check and see if your alternator is charging
Low voltage will cause those lights to come on, as the computer is shutting down.

To check your alternator you will need a volt meter... WITH the engine running you should have about 14 volts coming out. IF NOT you need to replace the Alternator!
