New to KZ's and having issues with my 77 400

As stated, I'm working with a 77 400 and the wiring was a complete rat's nest of jumbled poo. Nothing was wired correctly and the wires that were connected were spliced 3 times with wrong colors and thats just the beginning. Anyway, I can ride the bike but only on battery. The alternator isn't charging the battery and the r/r is not oem. Whoever installed it didn't bother to buy the correct one or even one that had the correct amount of wires in/out. I have a manual and have decided that maybe some alternator parts have lost their magnetism. My question tho, is where can I get alternator parts, and where can I get the correct r/r?

The rest of the paragraph is just background info in case anyone who reads this has any advice for me.

rewire it.

Used wiring harnesses can be had cheap on ebay and from the bike dismantlers. Save a lot of work.

Found a ton of info on another site. r/r wasn't working right.
