If the battery and alternator are good and the charging system is not working, then you either have loose or corroded wiring or the drive belt is slipping.
It is not really a battery light. It is a charging system light. It is on because the system has malfunctioned. Normally this means the alternator is not working properly.
Your charging system is not working. It could be the Alternator or the regulator or both. It's not a good idea to test the charging system by removing a battery cable while engine is running, this can damage the charging system.
Fusable Link?
NO. The battery light as you call it is actually the charging system light. If it is staying on the charging system is not working properly. More than likely the alternator has failed. It really has very little to do with the battery.
charging system not charging battery with new batttery, alternator and fuel pump. what will make that happen ?
Have the charging system checked. Possibly loose or corroded wiring, a loose alternator belt, or a bad alternator.
Apparently the alternator is bad or the battery is shot, take the car to autozone and get a free charging system check.
1. Alternator charging system malfunction.. [not charging enough]
new alternator not charging the battery
replace the alternator if your system isn't charging.
The battery light indicates the system is not charging. Have the charging system checked. If the alternator is not charging, the engine will quit running and leave you stranded.
Sounds like the alternator is not charging the battery up / WORKING check charging system. Charge battery to 12.8 volts and then start engine and hook volt meter to battery and it should read 13.8 to 14.3 volts. If it don't then replace alternator. Also need to make sure the alternator belt is tight.
