I cannot seem to figure out why my 89 gt with a 3g upgrade isn’t charging. Let’s start by confirming it is wired correctly please.

Do NOT reuse the stock 2G alternator power wires. The only wire from that plug to reuse is the the stator wire. Get off of Ebay or the Corral the 4 gauge wire kit with the 150 amp fuse and wire that directly to the back of the alternator plug and to the starter solenoid terminal .

Here is the install instructions
