Just picked up a 00 929 yesterday and been at it since. the previous owner told me he had drove it about 60 miles and it just stopped. I dont have power to fuel pump (fuel pump works tested), i dont get spark and the injectors dont fire , I have tested power going to ecu and the grounds per the service manuel and it all good. the diode in the ignition is bad, because when i turn on the pink wire dont get power. Now this is where i am at. What voltage range should be on this wire i have made a voltage divider circuit to limit the voltage to about 9 volts based on my research. but i still dont get anything. If i turn the kill switch on the FI light is on with the red light next to the neutral switch light. if i turn the kill switch off the red light goes out and a few second later the FI light goes out. I have tried to pull codes or anything but same if i jump connectors or if i dont. any help is appreciated the harness has been hacked n cut also by previous owner and it has a Power commander III if that makes a difference.

ok i cant get ignition out because of bolts but does the ecu need a certain voltage / current wat is the purpose of the diode can i bypass is to see if i need a ecu or not

Take the upper clamp off with the ignition still attached.
The diode is to stop people hot-wiring the bike.
I _think_ it's possible to put a 9-volt battery in the circuit to bypass it...maybe.

Ok so the upper tree clamp then ... Is there a way forsure to know if ecu/cdi works ... u mentioned 9volt battery works I made a voltage divider circuit that put out about 8.3 volts should that of worked

Ok issue resolved ... for future reference towards fixing the ignition, just unsolder the diode and replace with a 2.2k resistor mine started right up.. thanks for your guys support
