2003 Cadillac Escalade new Alternator not charging

Asked by Dec 19, 2017 at 11:13 PM about the 2003 Cadillac Escalade ESV

Question type: Maintenance & Repair

Recently noticed some voltage dips with the car (cutting out/Dying). I did the normal tests. Checked the battery voltage when car was off 12.2VDC, then when running 11.6Vdc. Pulled the negative pole from the battery and car died. I ran down and bought a new alternator and slapped that baby in and bada boom badda bing! Nothing! Same situation as above. I pulled the lead off the back of the alternator to measure voltage directly off the post and go 0VDC. Nothing at all. Need help at this point. There is another set of (what looks to be) control wires going into the alteranator. Im not sure if the alternator is dumb or does it get info from a charge controller. If so, where are the fuses or controller? Never! Never get a Escalade!

why did you pull a batt. terminal; when the test already showed the alt was no good ,? It's not a good thing to do when a computer runs about everything on the car , if the batt. wasn't charged and the new alt. had to do the job then you may have ruined it especially with rebuilt junk that they sell , the regulator is probably in the alt. one of those other leads could be the exciter because the regulator needs an initial jolt to make it work the other small one is feedback and the big one goes to the batt. , scan for codes
