bansheesandrider Posted March 23, 2010 Report Posted March 23, 2010 If the bike won't shut off with the off/run switch, then the off/run switch is not making a connection to ground. That has to be the problem, because that is how that switch works. If the coil itself was not making a ground connection the bike would not run at all, again, because that is what is needed at that location to make the bike run. There should definitely be a plug for the left handle bar switch and you should be able to unplug it and testy the function of the switch at that plug,consult a wiring diagram and you should be able to figure out where to place your meter leads to test what you need to. I just looked and with the switch unplugged, connect your ohmmeter to the black wire and the black/white wire in the switch plug. With the switch in the Run position the ohmmeter should read that ii is an open circuit. With the switch in the Off position, it should read that it is a closed circuit with very little resistance in it. If the resistance is high or it is an open circuit, then you have a defective switch. You can also plug the switch baci, go to the rear of the bike and unplug the 4 wire connector at the CDI box that has the orange, black, black/white, and red/black wires in it and test the black/white and black wires there for the same results I listed before. If it was OK at the switch plug but not at the CDI plug then you have a problem in your wire harness. The bottom line is the black/white wire coming out of the CDI box has to be grounded to shut the bike off, that is the sole purpose of that wire and Yamaha also tied the TORS system to this wire to shut the bike down if the throttle stuck. Hope this helps. Quote
NateDiggity Posted May 5, 2010 Author Report Posted May 5, 2010 (edited) Yup, now that you say that, there are bullet connectors for the headlights... I ground the pc off the coil mount, still no help.... any other suggestions? I only did a frame swap, and all connectors are connected... Ok, so I havent really looked into this for awhile, but I started studying this: and it looks like if everything is working except the headlights switch and on-off switch that the only 'common' wire is the black ground coming from the stator. Is this just a wire coming from the stator next to the four pin connector coming from the stator to the cdi? Im stumped, someone must have ran into this problem before..
