SR250 schematics

Last Sunday a few of us helped Mick sort out his SR’s wiring. The stock harness, in my opinion, is unnecessarily bulky with safety relays and switches. This inspired me to see if I could design something streamlined while still using the stock controls and dash gauge… this is what I came up with:

I found the stock diagram at the Philly Free Library. They have a decent selection of automotive and motorcycle manuals in their reference section. “Being a Yamaha owner, you obviously prefer a quality product”… These old shop manuals are awesome.

    See if you can find any flaws in it but I am confident that this works… The Yamaha setup is a bit different than the Hondas so it was different than when we did your 650.

    I can scan the OEM diagram and my diagram at work for a bigger high res copy.

    Mick, one of the copies I made front the Yamaha service manual has the introduction to the TCI unit which I bet has the procedure of how to test it but I don’t have copies of the following pages unless it’s on one of the sheets I left with you.
