I'm at a lost my friends and need any suggestions you may have. My alternator is not charging my battery. Only reading 8 volts in the dash gauge. My alternator is the Delco CS130 series, with the 3 prong connector. I've taken my alternator off and had it put on the machine at my local Autozone. It checked out just fine. I was looking over his shoulder. Put a good charge on my battery with my battery charger and reads 12.6 volts. My positive battery cable has the 10 ga. wire going to the alternator, along with the jumper to the fuel pump fuse and another orange wire feeding into the engine harness coming out of the firewall. My question is there an inline fuse link encapsulated in the 10 ga. wire between the alternator and battery ? Also the 3 wire pigtail connecting to the alternator has the white wire clipped off at the pigtail, meaning only 2 wires coming out the pigtail. Is this correct ? It must be because it's been that way for as long as I have owned the GTA. I understand that these TPI engines will run like crap if not getting 12 volts all the time. As mine is. I've also heard this charging circuit runs through the oil pressure sender, but I'm reading good oil pressure in my dash gauge...I'm stumped and any help will be appreciated.

Thanks in advance....
