Why is it that when my 91’ stang gets to operation temperature, I loose major voltage? I have upgraded to a 3G alternator which seemed to help slightly but I am still having charging issues when the cars get warm. Any suggestions or recommendations would be appreciated? Thanks in advance. :confused:

The batt is pretty new and I belive the wires were also upgraded. Is there a way to check if they were? Which wires should have been upgraded?

there should be a 4 guage wire on the pos post on the alt, it should go to the starter relay with a fuse.

take care,
adam
