Installed a new Bosch voltage regulator and that did not solve the problem.

. I spent about three hours under the car attempting to remove the alternator and wass unsuccessful. Turns out the tension adjusting bolt was bent. I had the car towed to my local indy and had them R/R the alternator.
Anyone knopw what to do with my dead core? The Ebayer did not requier a core exchange. Does anyone buy this or is it trash.
