So it's stopped raining and being 40 degrees outside so I've taken some time to go through the electricals step by step to try and figure out what is wrong with my bike.
This is a continuation of this thread here:
Stranded! bike died. help please.
Summed up, my bike shut off out of the blue while idling and after that when I switched key to ON, the pump would not prime.
So, I found a thread on this forum where someone copy/pasted the service manual's instructions for diagnosing this problem.
The fuel pump works when I jump power to it. Both the fuel cutoff relay and the engine stop relay work when tested. So, according to the service manual, the bank angle sensor is the only piece left to the puzzle. If the bank angle sensor isn't it, the manual has you start testing the ECU wires...
Now, I don't know where the bank angle sensor is, but I found what MUST be it right next to the engine stop relay and the ECM - it is a black box with a flat top and the word "UP" on it with an arrow pointing up and the three wires (green, red, white) going into it.
What's confused me is that I've found threads on the forum from bladeracer and others stating that the bank angle sensor is behind the headlight...??? So that confuses me as this box is under the tank not by the headlight.. could someone clarify this all for me?
Anyways, assuming I've got the bank angle sensor located, the service manual excerpt instructs to simply ensure it is plugged in and vertical and turn key ON - if the relays click, it's doing it's job... well I do this and the relays don't click. Obviously not right. But, this seems a rather unthourough test of if the sensor actually works - mean, if the ground to the sensor is loose, it won't work, and replacing the sensor wouldn't fix that... so, anyways my question is, is there ANY way to bypass it to see if the bike would start if it WAS doing it's job, or any way to actually test the sensor itself for proper operation??
The sensor is ~$90 and a special order item so if I buy it I can't return it if I plug it in and it doesn't solve the problem, so I'd like to be sure it is the issue. But I guess really I need to know if I'm even looking at the right sensor since some are saying it's behind the headlight....
Thanks!
