Any surging of the tach up and down or is it completely dead? If you had surging I would say it was in the sensor or it's positioning (which should have been fixed with the new sensor). Since the alternater is RPM/tach driven you may not get a charge until it is up. If both are completely dead I would say it is up higher electrically, sorry I'm not much help when it comes to that. Hope this kind of helps.

Ron,



What year is your truck?

The plug infront of the #1 valve cover can also work loose (happened on mine) and can cause it to go dead or surge.
