Hey guys I'm new to this form but I was hoping someone could instruct me on had to figure out the two wires on the start stop kill switch harness for my CBR F4i 2002 I'm not sure which one connects to which post on the handle controls

 

Do you have multimeter and know how to use it to measure voltage?

This is 5-minute fix with multimeter.

 

Sorry I was working yesterday I appreciate you trying to help out yes I do have a multimeter and know how to measure voltage

 

I was reading a thread about a no fuel pump prime on a 2002 f4i which is the problem I was trying to fix with mine that lead me to switch replacement problem. Can anyone verify that checking continuity just mean making sure there is no brake in wire.im searching for a main wire harness because the one on the bike is in bad shape and hacked up. I'm trying to get bike back to stock

 

Yes continuity is no breaks, but not easy to do because you need access to both ends of wire. Easier to just measure voltage at particular junction by backprobing connector. If here's power on output wire of switch, then switch is OK.


Not likely those switches are bad because bike will not turn on at all if any if any of them were bad. Measure voltage along entire path starting at battery to kill-switch.

Verify kill-switch switch input wire has power. Then when switch set to RUN powers up output wire.

Most common cause of no pump prime is bad relays.

Don't replace any part until you've measured it and numbers tell you its bad. Otherwise replacing perfectly-working parts with brand-new perfectly-working parts changes nothing and bike still won't work.

Trace and measure flow of electricity from battery to fuel-pump. Measure every connector/junction in between. Obviously you'll have full voltage at battery. Then follow wires to fuel-pump and measure voltage at each junction. Where voltage disappears where there should be power needs closer look.
