93 civic dx battery light problems

[Cnk]

Having trouble with the battery light coming on, seems to only happen after driving the car and getting into higher rooms. Has after market exhaust and is wired for subs and fog lights. Have had the battery and alternator tested.

Don't rely on just one shop testing the alternator. Try this and go from there -
