Default alternator/charging issues

so i replaced my alternator cause my old one was bad. It is still not charging the battery. I have double checked the connections to the alternator and all the grounds "battery included". I replaced my starter a couple months ago and everything works fine with that but i dont remember there being a big ground connected to it. but i was tracing wires and grounds and i found a ground that is underneath the intake manifold. Does it connect to the starter? I need help i cant figure this out. Does anyone have a wiring diagram? any help would be much appreciated. Thanks

so come to figure out that ground was the power coming from the alternator...however its still not charging the battery...I am at a loss i have been trying everything and have no clue what it could be...any suggestions? There is the power wire that comes off the alternator to the starter...Check....then there is the two prong connector that plugs in to the alternator check....I have no clue what is going on..any ideas? Please I am tired of not being able to drive my baby. By the way it is a 03 if that matters

Having them switched may have damaged the PCM, which is where the voltage regulator for the alternator is located. Remove the PCM connectors and see if the pins on the PCM are scorched.

You may have ruined the battery. Get it tested after?

ya but the car should still be putting out 13+ volts. its only putting out 11.56 when i tested it at the battery and at the starter and fuse box...I could try a new battery but i dont think that is the issue. I tested the battery when the car is off and key off and it was putting out 12.04 volts and was not dropping.

I say get it tested at a store like Autozone. My battery was putting out 12 volts, and even passed the test where the coil heats up in the hand held test thing. (Old ass technology) Autozone showed me it wasn't accepting a charge like it should, but it was releasing power fine.

I see you are in Germany, maybe they have the German Autozone there, "Achtun-o-zone."

I vote PCM.

Service manual pages 572 and 573. On the PCM it's connector #2, pin 19 and connector #1 pin 29.

Of note, the battery temp sensor or ambient air temp sensor (depending on year of the car) also play a role in the voltage out the PCM decides on.

Yeah, if the alternators good once it's running you can disconnect the battery. If it stalled when you did that there is def an alternator problem.

Default found somethin

Hey I thought i'd just post this to help others in the future.

I had my charge wire chaffing against my dump at first.



so I fixed that and wouldn't get a charge to battery still. I did some more digging and found the same charge wire at the starter had burned through as well.
