I have a b1750 I just picked up and the regulator was disconnected and the connector on the harness side is gone so there’s just 6 loose female 😀 connectors. I just picked up a connector kit and realized the wire colors on the harness aren’t the same as the rectifier. So a pic or description would be amazing!!

I’m not sure if this helps you any. I tried to pull it up to see if it would and had issues with it loading (likely on my end).
This should put you on the right track.

The first place to look for wiring diagrams for older B's is in the operators' manual not the WSM.

This is the wire color table.

The two blue wires come from the dynamo and they are interchangeable.

If this is still confusing ask more questions.
