need help/ not charging..I think

Do you have 2 spade connectors or one on the back of the alternator? If only one with the engine running when you put 12v to the spade and the alternator will kick out full 60A (in the case of the one I have on my 340) and if your headlights are on they should get brighter. If you have 2 spades then you can ground one of those and touch 12v to the other and get the same result.

The wire(s) come from the output of the regulator which sits on the firewall in front of the driver. My 340 fish has a single wire and the output wire is on the top. BTW, that is where I have the switch (I run the connection between the regulator to the alternator inside through the switch) that cuts the power from the regulator output to the spade on back of the altrnator to turn off the power to the alternator, reducing power draw from the engine since no engine power is used to make the 60 amps and it speeds me up a tad.

If you have a 2 wire alternator the regulator will have a plug that the wires to the alternator - that 2 wire regulator is supposed to be better but talking with an old school chrystler alternator repair shop guy may not really be better after all.

Good luck. If this stuff does not make your lights brighter or the alternator output voltage higher then they may have screwed up the alternator. That will be another topic but no big deal.
