Sir , the altenator has 3 wires at the connector correct ? a white/red , a green/white and a black , the white/red wire is involved with a 10 amp fuse to do with the charging meter / gauge , the fuse located behind left side of dash .. the green/white wire is is involved with 2 fuses , a 10 amp ECU fuse and a 25 amp Main fuse located at left rear of engine compartment main box , and the black wire is involved with a main 80 amp fuse at the main box also . both of these 2 wires end up at the positive side of the battery , please verify all these fuses are good . if they are indeed good , then open wiring would be next step verify continuity on black and the white/green wires . i would post a link to diagram but autozone repair info site is down at this time . if ya need more help , please ask .

I have a 99 Pontiac grand am gt that has a good alternator that isn't charging the battery. The wires are connected correctly and the connections are clean and the battery terminals are clean as well....


Have you taken the battery to autozone or someplace and had the battery tested? I would find if you know the alternator is good it must be the battery itself. Might want to try that if you havent already. Good Luck Bro~

Battery light comes on


the battery light coming on may indicate that the alternator is not charging,it should come on when the ignition is switched on & go off when the engine is running, you need to check if the battery is being charged or not......hope this helps.....cheers

Battery not charging


I would check the altenator again. if you didnt disconnect the battery and a spark shot off while installing the new starter it could have decharged the spool on the inside of the altenator to where the spool no longer charges. if you have the altenator checked for consistant charging and it comes up good check the relay for the altenator it most like will have messed up the relay. to make a long solution short check the relay for the altenator it will be in the relay box under the hood.

there is a chance that the battry is faulty but there is also a chance that the alternator is drawing voltage back out of the battry when its not charging, this would be because the diods that stop the voltage flowing back have broken down. to see if this is the problem charge the battry,refit, but put a bulb in line on the possitive teminal if its glowing bright the alternator is drawing back try disconecting the altenator and testing it again if the bulb stops glowing you know its the altenator, dont forget the interior light will make it glow too. its also worth checking the earth straps.

1995 Jeep wrangler not charging properly


lf you have replacement cable ends on your battery, check that wires are not corroded under the straps. Also check alternator ground (run a ground wire directly to the alt case) I have seen "lazy" regulators at times but this is very rare. Also make sure drivebelt is tight enough to prevent slipping. Has your battery been charged and load tested?

Battery and brake indicator light stays on after start


When the lights are on check the battery voltage. Should be 13.0 to 14.5. If you unplug the connector on the alternator when the lights are on, do they go off?

Car shut off while driving won't restart


check your battery termanals, make sure they are clean and tight. could be a bad battery or just need charging. also could be the altenator. try jump starting it first.
