Do you know for sure that the alternator is not charging or it's just not showing at the gage?, you lay a metal screw driver or a feeler gage blade up close to the center rear bearing and if it's charging it will suck the screw driver blade up against the bearing cap, it's the fastest way i know to check if the alternator is charging.

thanks zipper. I didnt have it wired right . I looked at my buddys truck and checked the wires with a test light. I only had a jumper to the back post and no switched power to the other. ops: Its charging 13 volts now! Thanks for the response you guys are very helpful on here.
