So recently I have been getting a brake light and battery light. My assumptions is my alternators is dying, even though Autozone said it checked out. I have recently added the Big 3, and tried a diode alternator mod. Seems better, but still dips in voltage, thus the lights. Also assuming, my sound system, hids, and other minor accessories are drawing too much.
So I am down to getting a new alternator with a higher output. I have found a 2011 WRX alternator, and I am not sure if it is 110 amps or not. Or if it will fit my 04 wrx. Anyone know? I have been searching on the forums all day.
Anyone try Maniac 140 amp alternators?
