So Im back to getting my bike up and running, well the bike just didn't fire up. So this is what I theorized = when the bike was broken down I went through the same process as I would if I was just storing it, so instead of going through the whole trouble shooting process I started with what I had changed. i.e. the ignition. I measured the volts coming from the anti theft wire and was not getting the correct amount of voltage so I moved to the battery. with the bike off I was reading under 13V and down to almost 11V when the bike was turning. I charged the battery over night and got a reading of 15.xxx while the bike was off that settled down to 13.20V and back down to high 11.xx V. So new battery?? or is there a way to bring the life back to this one. And another thing I noticed when I turn on the ignition, (in the past) the fuel pump would prime if I flicked the kill switch to on first, now nothing happens. Any ideas on that, it worked great before (strong and reliable).

Thanks guys. hope you agree with what I've found

 

so yes?

 

Yes and no.
There is no way to bring back a bad battery. It must be replaced if it's bad. High 11v should be enough for the pump, it's the starter motor that needs most of the amperage on start up.

If the pump isn't priming, trace the voltage through the system. Does the pump have power at the connector?

 

Sorry demon for not responding sooner I've been swamped with work and life but no no power to the fuel pump on either connection. stater works Im pulling a friends battery to see if thats an issue before I drop the $$

 

What do you mean "either connection?" There is one connection with a power and a ground. The other is for the gauge. Use your diagram and trace the power from the ignition and fuse block through the switches, connectors, and relays all the way to the pump.

 

sorry either end of the connection. I was making sure that it wasnt the connection that was the problem. I dont havegauges attached would that cause the bike to not start. I'm really leaning towards the anti theft wire not sending the correct voltage though. I know the bike requires ~9.3v going into the ICM and when I hit the starter switch the voltage drops to as low as 7v. The fuel pump draws its power through the ICM as far as I can tell from my wiring diagram. thats why I thought it was the battery. Im on the hunt for a cheap ignition now to try that.

right now I do not have the headlight, gauges or the left hand controls pluged in because I was told that the F4 doesn't need them plugged in to run, is that true?

 

I'm not sure, but I thought it did. Plug a bulb in it any way and see if that works.

 

I will tomorrow. Work has got so wrapped up its insane. Last week I had all the time in the world and now I'm lookin at at least 15 hrs of overtime. More money for the bike

 

Whenever you get back to it, I'll be here....
