Need information on 2000 Pontiac Sunfire charging system


To check the alternator on GM's. Start the car, pull the negative post off the battery. If the car dies, the alternator is bad. If it stays running. Check and/or replace the battery. Also check and clean or replace badly corroded wires from the battery.

01 sunfire battery stays at 12.5v


I guess my first question is what is the alternator output at idle ?
You can't test an alternator by disconnecting the battery like we did 40 yrs ago with generators. The alternator needs the battery in circuit to perform. And now with computers, you can cook a computer by disconnecting the battery with the engine running.
You should have 3 wires coming out of the alt. The large red wire goes to the starter with a fuseable link. The other two go to the computer. They turn the regulator in the alternator on and off.
What is the voltage on that red wire with the engine running ?

Why the interior lights want go off in thr cadallac deville 98


Could be a bad fuse, battery or alternator. If they went off and stayed off then it's probably a fuse. If they dim off and on then it's probably the alternator and/or battery but I would replace the alternator first.

Good luck!!

I have a 98 pontiac sunfire 2.4 . I just replaced the alternator and found out that it was missing the electrial plug. I located two cut wires but still no plug. I brought a 4 wire plug with pigtails from...


Hopefully this helps. In the wiring diagram the B+ wire is the large red battery cable that bolts to the back of the alt and is not part of the plug.

Battery light staying on after brand new alternator changed out please help


Hello and welcome to FixYa!


As a first course of action, I strongly suggest that you have the battery charged. It can be an indication of a weak battery or a faulty alternator. If the battery light still on after charging then the problem will surely be on the alternator itself. If that's the case the alternator should be replaced to resolve the problem.


You may try to reset it to by removing the positive battery connector, letting it sit for at least 5mins. then reconnect it again. This will reset the system and can get the battery light off.


Hope this helps and thank you for using FixYa! Have a good one!

Flickering Headlights and Dim interior lights


Definately an electrical problem....first off, check the battery and alternator connections to make sure they are tight. The problem has to be before the fuse box because the headlights and interior lights are on different fuses. It sounds to me like a loose wire, corroded battery terminals, or an alternator that is going bad. An alternator is a relatively easy and cheap fix. They cost about $100 and require removing a few wires, 3 bolts, and the serpentine belt.
