low voltage

Post by failure »

Hey guys my car keeps telling me low voltage. It only happens when I get on the gas hard and it gets high on the rpms. The light will stay light for about a min or so and then go off. Bad alt or what the battery has 14 volts while idling.

Go to AutoZone or Advance and get a test done. Could be a list of things.

Possible culprits:
Battery: Have it load tested.
Alternator: Have it tested.
Corroded cables: Check the positive battery cables especially. Slit back the insulation and inspect for greenish copper corrosion in the wire. If it's good, repair the insulation slit by wrapping with electrical tape.
Corroded grounds: Check the ground busses for corrosion under the carpet in the front footwells.
