Author Message   Sgthigg Posted on Thursday, July 01, 2010 - 05:45 am:        Here is my situation. Bike wont turn over. I simulated the start relay closed, and it will start. However I have no relay coil power present at the terminal block. Start Switch checked good. Open and close on depress. However no power present. Moved to connector behind wind screen and good there. No power present there either. Clutch switch working as well. What else could be the problem? Is the only thing left the wire to the main terminal block? Please any suggestions welcome.   5liter Posted on Thursday, July 01, 2010 - 08:34 am:        Side stand switch?   Buell_bert Posted on Thursday, July 01, 2010 - 10:56 am:        Hello there. What model of bike??? At least someone will know what schematic to look at. Also do you have power to other things.   Sgthigg Posted on Thursday, July 01, 2010 - 11:44 pm:        Sorry about that. Its an 05xb12scg. With no side stand switch.   Rays Posted on Friday, July 02, 2010 - 09:34 am:        If it will start when you bypass the start relay then you are getting switched ignition via the kill switch. The power for the ignition relay comes from the kill switch and there is a second wire from this point on the ignition relay running back to the start button. If I am correct in saying the bike will start then there must be power at that point (pin 1 on the ignition relay). If there isn't power on the Starter button (the soldered wire, not the screw connection) then there must be a break between those two points. I just went and double-checked my theory on my Uly (I'm guessing this part of the wiring is pretty much the same) and with the ignition on and the kill switch off there is +12v on the Grey/Orange wire on the back of the killswitch. There is no voltage on the soldered connection on the Start button (the manual shows White / Black but I thought the Uly was White / Red - I'm not going to pull the throttle apart again) but once the killswitch is flipped there should be +12 volts at this point. The other wire on the Kill switch and the wire on the soldered Start button connection should be joined at the back of the ignition relay socket. Hopefully that all makes sense...... Of course if by 'start' you mean it will crank then I'm way off the mark.....
