at higher rpms my lights dim and the battery light faintly flashes, did it before the 3L, and it still does it now!


while the engine was out, i ahd the alternator tested by a shop that rebuilds them, they said it was fine


also, i do have a system, but it does it even with it off

i was on an open highway at night, high beams on, punched the gas, redlined it, the lights got really dim

id like to know whats wrong
