Soldered on new connector.
STILL NO CHARGE.
Got no words.
Something is not right with your wiring or alternator/regulator. Get rid of ALL the stock wiring and rewire with just the new pig tail and some that you picked up and some 14 gauge. Heres a wiring diagram of how it should be.

DON’T wire based on color! There is an “a s i” stamped into the 3 prong plug on the back of the alternator, wire based on this diagram.
But, instead of taking the “a” wire straight to the solenoid, cut the stock wire out and just use the length given to you in the new pigtail, crimp a loop connection onto end and connect it back to the alternator at the b+ output post along with your 4 awg output wire. Some don’t like to do this, but it won’t hurt anything, and in your case it will just help deduce the problem and simplify things. The “a” wire is just your 12v power for the regulator.
Then take your “s” wire with your stator plug end and plug it into the male stator prong on the alternator. Make sure the plug on your wire and the prong in the alternator is in good shape and is making a good connection, otherwise just go buy a new stator plug and solder it on, and clean up the plug on the alternator with sand paper. The female stator plugs are like $5.
Then take your “i” and make sure its connected to the cab battery warning lamp wire where it was originally. This could also be your problem. If your battery warning lamp in the cab is out and the circuit is broken the regulator may not be kicking the alt on. The blue bubble on the wiring diagram i posted explains this and how to resolve it, I have never experienced this myself though.
Then of course, check your connection from the b+ post, to your megafuse, to your solenoid, and then to your battery. If you’re not getting power to the “a” wire, then the alt reg won’t get power, and then your stator won’t get power, and it cant produce power, and if you don’t have a sufficient connection from the alt to the battery you won’t get a charge from the alternator.
And of course, make sure you’re alt has good belt contact, you’re running the correct pulley configuration and that its spinning in the right direction. You could have a counter clockwise alt when you motor spins it clockwise. Not sure if the 3gs came in a counter clockwise variation.
Thats all I got. If none of that works then I’d try a new alternator/regulator. The circuit is pretty simple other than that “i” wire that goes to the light in the cab, so maybe check your wiring there and check that the light is functioning. Power Probes are great for that kind of stuff. Best tool a $100 can buy imo.
When you have everything connected like I said, post pictures that clearly show what is connected where at the alternator, and then pictures of your solenoid and battery connections as well. Maybe we can point out something that you missed.
Good luck!
