Battery or Alternator problem?

15

Asked by Oct 02, 2016 at 04:36 PM about the 2004 Mitsubishi Lancer ES

Question type: Maintenance & Repair

I go to start my car by a boost. Once the car is started and boost cables
are taken off the car battery light comes on, revs up on its own till battery
light goes back off, then repeats the same process. Sometimes she even
shuts off.

However, when the car is still running and we take the battery posts off, the
alternator is able to run the car fine on its own. Many people tell me
different things from; battery problems, alternator problems, and even
wiring problems.

More information would be great!

You can check the battery and alternator without removing the battery cables, which can be dangerous. Battery at rest should be 12.3V or higher, engine running it should be around 14V. Anything lower than 13.5V , the alternator needs replacing. It simply isn't charging the battery enough.

Thank you, It is indeed the alternator, as it is 85amps and I need a 90amp.
