Not a batt yet I have a new one in hand for when I get home. I've checked voltage at power supply. Check battery voltage at pink wire on connector from pcm. And power at blue to batt light and all is good. I even grounded blue wire to check light still worked
Well I would try a new battery with the new alternator then check back with us.
Battery changed nothing. If the car is only running at 12 v y is my battery light not going on? Its like there is nothing telling the car to charge. Is there a way to by pass the regulator to just see if the alt will chargeOriginally Posted by camopaint0707
I'm not sure what you are trying to say...
On some gm cars you were able to by pass the regulator by grounding it and the alt would charge at full potential. I'm wondering if there is a way to for so here. And I am also thinking could my ecm b bad does it control the regulator.
I'm just going to return the alt and get a better brand to see if that changes anything if not I'm going to replace the computer. Other than that I'm Sol
Have you taken your car to a shop for this?
