Alternator wiring repair question on 4.3 MC

[Watermann]

I'm in the process of pulling the alternator to have it bench tested prior to even worrying about trying to fix the wiring problem. Here is a pic of my alternator where the PO had ripped the positive batt+ and the ign+ wires out of the back and then did a shoddy repair to them. There is no repairing them now as when I got the donor motor the wires were broke off where they enter the case insulator.



And what the wiring is from a schematic.



When the alternator tests out good I plan on breaking open the case and replacing the wires internally. I've never done this with a marine version alternator before but have soldered many wires and circuit boards with success. Has anyone done this before or have any tips / suggestions to pass on for this job?

That is only a plug end that plugs in the alt first, then the screen cover goes on. No big deal for and repair facility
Bit I would have it changed to a single wire alt .it eliminates those 2 wires.

Yeah I thought about converting to 1 wire but I would still have to do the repairs. I actually prefer the 3 wire set up to 1 wire and I know there's some debate on the subject but 3 wire is said to have stronger more consistent voltage to the ign mod and the electrical system. Also I think my harness uses the 3 wire for voltage sense at the dash gauge. Just repairing the wires and not dropping a bunch of bank on a new alternator is really my goal on this. The 3 wire isn't a big deal to me and the wiring harness is in good shape.
