Ok, I need to get the last 8 of the vin number to pull the wiring schematic for the charging system
Ok, once you get the last 8 of the vin, I will pull the schematics and walk you thru the needed testing
Ok, with engine running check voltage on the yellow with black striped wire and the brown wire at the alternator and let me know what they are
Engine ground for this
Ok, which color wire was reading 1.35 to 1.4v
Ok, let me know. Also, check fuse 14 in the fusebox under the driver side of the dash
ok, see attached for its location
Based upon testing, the new alternator is defective out of the box.
The yellow with black wire is the wire from the fusebox to the alternator and energizes it. The brown wire goes to the instrument cluster and should have batt voltage out of the alternator. So we have 12v going to the alternator, but not going out to the cluster and not 13.5v going to the battery. These all point to a defective alternator
That one doesnt make sense as it feeds the yellow with black wire which does have 12v. Is it possible that you didnt get a good connection on it
I honestly am not sure why it wouldnt have 12v yet the yellow/black wire it feeds has 12v
Ok, check some other fuses and see what they are reading
