Dude, No offence but you should have someone else do your electical work. I'm really not trying to be a d*ck but in this thread you've made it pretty clear that you're not up to the job.

Ps. Resistors are measured in ohms, not volts

Edit: I still haven't looked at the diagram so I've yet to see what we're dealing with but if it's a diode it's there for a reason. Zener diodes cost more to manufacture than resistors so if a resistor would have done the trick honda would have used it.

 

While that may be true, the wiring schematic shows a very direct and logical path, not necessarily requiring a diode. I used resistors on my f4 and my buddy's 929. No problems so far. I would have bought the zener diode if my local radio shack had them in stock. However to each his own.

 

Think of a zener diode as a voltage regulater and check valve all in one so you connect the anode side to the 12 volt red wire on the ignition switch and the cathode side to the green wire that turns to pink in the wire harness thus necking down your voltage to 9.1 volts and your bike will prime and should start.
Or connect tthe positive side of a 9volt battery to it and the negative side to your battery and that will trick the cpu to function as it should
