ok so I changed the timing chain/gears in my 2000 Jeep Grand Cherokee Laredo ..4.7 v8. Now AC pump does not cycle,( I did not disconnect it for the timing chain repair), and my alt don't seem to be doing its job,(it worked worked before). there is a Ground lead coming from the P.C.M. about a foot long and covered in black insulator and I dont know where it hooks up at. was wondering if that could be part of my troubles any suggestions r greatly appreciated
