What should I do if my Battery Light keeps coming on?
What should I do if my Battery Light keeps coming on?
Charge the battery fully and take the vehicle to a local auto parts store and see if they can run a charging system test (usually a free service). They should be able to tell you what kind of shape your battery is in and the alternator output.
Why does the battery light stay on when I change the alternator?
If you changed the battery first, then changed the alternator, this may not have happened. Sometimes it’s as easy as fully disconnecting both terminals and reconnecting the battery. Check the voltage from the positive terminal of the battery to the negative terminal on the battery (record this).
Why is the battery light on but not charging?
Either way the alternator is not charging the battery and it’s the fault of the voltage regulator. Ask the person doing the test if he can tell you what the field voltage is on the alternator. If they can and it is around 12 volts or more you can probably bypass the next test.
Why does my car battery keep coming on and off?
If not charging properly, a new battery may keep you going for a while, but sooner or later will eventually crap out on you. If the voltage is good going to the battery, you should be ok. Good clean and tight connections are also very important, positive and negative are equally important.

When does the battery light come back on?
The battery light comes on and stays on for about 30 seconds then goes off. After this, the dash lights and radio go off. Most of the time they come back on within a few seconds.
How can I tell if my Battery Light is working?
Ask the person doing the test if he can tell you what the field voltage is on the alternator. If they can and it is around 12 volts or more you can probably bypass the next test. Start the vehicle and hold a steel tool near the back of the alternator (not on the pulley side). It should be drawn magnetically to the center of the alternator.
