Hello there . I need some advice. suddenly ,my engine start switch button doensn't work .when I push the starter button sometimes works & sometime won't works .So I look through the internet and find a OEM part, they need $164 dollars including shipping cost to the sri lanka .that's too much .I could buy a ( 2001) newer model OEM stater switch a lot cheaper ( $50 dollars )than the older model one. actually older modle oem part discontinued & hard to find .I could easily swap a newer oem switch over older model what do you think ? will it works or won't works

Many times you can just clean the contacts. Have you tried cleaning your contacts first? You should be able to use a newer switch. A newer switch could possibly require moving the wires in the connector but that is easy to do.

The plug may not match up, but if you have three wires coming off the old switch then it's just a game of figuring out which wire matches the other as most likely the wire colors will be different. If you can find them, I would use Posi-Lock connectors, excellent wire to wire connectors that can be undone in seconds, and re-used:

I would assume Black is ground(confirm with a muti-meter). If so, my guess would be to combine BL/W with B? Test prob all 3 wires before hooking anything up.

Maybe someone here with more electrical background will chime in....better than my WAG(wild ass guess).
On second thought, maybe it's the R/W and B......hard to call with out it in front of you and using a meter.

When mine failed on eve of an out-of-state trip I replaced starter switch with an old house door-bell switch sitting in a drawer. Aaah, the miracle of Zip Ties, much less messy than duct tape.:)
Once home I installed a generic combo switch I had ordered for around $10. Correct wiring was easily determined with multi-meter and a little logic. TWs are a little different in the kill switch with reversed polarity from most other bikes, a question of an open vs a closed circuit being required for engine operation.

I used an intermittent switch that had a round button on it. I had to rig up the mounting inside but it looked like the factory switch when I was done. That wasn't on the TW.
