ive been have charging system issues and need help. i replaced the alt with a.good used one. its been tested. i bought a new stage 1 ecu from zzp and i had sears check the battery and said it checked out ok. my charging system light comes on when i drive the car. itll go on and off at first then after about 45 min to a hour itll shut down my abs then power steering then lights go and itll die out. i had a mechanic and the local alternator rebuild guy check it out and the.cant figure it out. but both think possibly the pcm. but i think o changed that if its the same as the ecu. anyoje have similar problems or have any ideas
