:flag: Alright well I finally got my car working. Only problem now is that the battery light comes on when I give it some gas. I tested the battery and it was at 12.4. Any suggestions? I'm going to get my alternator tested later today. :flag:
 
You should be seeing 14+ volts at the battery with the engine running. 12.4 volts is basically just the battery. I have seen alternators with only 5 of the 6 diodes working that give just enough charge to put the light out but it will flicker at times.

Throw the voltmeter across the battery terminals with the engine running - you should see 14+ volts. Anything less than 13 is probably no good.
 
i checked the battery and it was good. The alternator wasn't able to be tested because it didn't fit right on the machine at autozone. Which means I'm going to have to end up buying an alternator.





What should the cranking amps on the battery be? I checked my battery and it was 500. Shouldn't this be much much higher? Any suggestions?
