Hello,

My uncle gave me his old RT1 as a gift during the pandemic and I am just getting to work on it now. He was pretty rough with the bike in his younger years so I'm trying to bring it to life. Full engine/transmission rebuild has been completed, now all it needs it the wiring! Unfortunately, I am not the best with electrical work so making a new wiring harness from scratch has tested my knowledge. After looking back and forth from the wiring diagram to the actual harness it is clear that it has been tampered with, making it hard to follow.  

There are two black wires from the stator, one comes out of the loom at the same spot as the other wires (yellow, green, green/red) the other comes out about half way down the loom. I creating a test circuit: the ignition switch black wire connected to a "T", one side going to the ignition coil, the other side going to the stator black wire, and separately the black/white wire from ignition switch to frame ground. This circuit allows the key to cut spark when in the 1 position while allowing spark in position 2 and 3, as intended. This leaves the short black wire from the stator with no home. Where does this wire go?

Lastly, what is the peak and idle output wattage of the stator?

Thank you for reading my rambling mess, this community has already helped me a ton just from old posts and diagrams in the library. I hope to be riding around very soon!

 

DEET sells wire harness's . All original and it is the way to go!

The short black wire from the Stator is for a test probe and should never be hooked up to the ground circuit.
You will get a " No Spark " situation.

I appreciate all of DEETs offerings and services, they look very professional. I would just rather do the tinkering myself, that way I will always have this skill. Thank you for your answer and quick reply!!

I am also looking to modify the harness from the original diagram to accommodate some after market lights and switches. Not all of the original parts are there and I don't currently have the funding to buy all OEM at the moment.

Besides replacing the factory stator assembly with a 12v stator, is there a practical way to convert the lighting to 12v? I am looking to use all LED lights around the bike instead of 6v. I already have a nice and compact 6v to 12v step-up converter that I am pretty certain I can use after the battery in the circuit for turn signals , horn, and stop light. That leaves the headlight circuit at 6v though, would I just need to add a second step up converter in the headlight circuit?
