We don't have oneA voltage meterI replaced alternator as well as battery yesterday and the battery light came on drained and then lost all power to vehicle... exchanged parts again and it stil is doing the same thing
Automotive Expert
ok, in order for me to help you. you are going to need to help me by having a multimeter because it's very possible the PCM is bad because that is what controls the alternator.

Thanks
Automotive Expert
may I have the VIN please
Automotive Expert
please standby
Automotive Expert
as you can see and read on these 2 attachments, there are no fuses involved in the system and it relies on the PCM to control the internal voltage regulator inside the alternator. (attached)
