With the ignition and kill switch in the run position do you have power at #87 on the system relay ?

Nope!!! 00.06v at pin 87 with both switches on!

Looking over my other posts, I might have forgotten to mention that the 'red key' light stays on, is it possible that it's the TSSM and not the ECM?
I've tried all various versions of how to reset the ECM and there is no change.

I wish i was better at this and more would chime in as im the last person you should listen to --------- but if that red key light is on you are locked out on the security system do you have a FOB or can you override the code ?

Ahh, wouldn't that be funny if that's all it is!!
I've tried the 'TSSM reset' with no luck. The fob arms and disarms the alarm with all the right beeps and signal flashes.
Doesn't the alarm disable everything? Or just fuel and ignition, because the bike still turns over, just won't fire up.
Thanks, Matt.

Ok, now I've tried the 30 minute TSSM password learn, and still nothing! The odd thing I noticed was the dash lights weren't doing as described in the instructions I followed and by having the ignition on for 10 minutes at a time I heard the relays randomly clicking and the fuel pump intermittently cutting in and out, enough to get fuel pressure up to 52psi, but bike would still not start, cranked over perfectly. So I think that maybe this tells me the ECM and TSSM are possibly ok! Some power is getting through some of the time. So I'm thinking still a bad connection or a short somewhere???

I have power at #86 & #30, but not #87 or #85. Not sure if that means anything or not?!?

[QUOTE=Oz Nightrain;15663471]I have power at #86 & #30, but not #87 or #85. Not sure if that means anything or not?!?

#86 is power from the ecm which should cause the relay to switch and power flow through from 30 to 87

Also check the wire from 85 this is the neg or ground for the relay circuit if there is a break there somewhere the relay will not switch

Also remove the relay and ohm 85 and 86 those are the relay coil terminals and if open then the relay is no good

With all you have done i would concentrate on the wiring from 85

Good luck

Dave

Thanks Dave, I really appreciate your help on this! And I think you may be onto something there!! I tested the 3 relays that I have and they all had similar results, between 65 and 75 ohms. So I guess that means if there is resistance there the relay coil are ok....maybe?
Now for the tricky part. I've had both fuse blocks out, which was a PITA, along with the battery and have only just put it back together. So I thought if #85 of the relay is ground, there should be continuity between it and the neg batt terminal. I have absolutely nothing between #85 and ground. Am I understanding this correctly? If I am I think there's a good chance of this being the problem and I'll owe you big time!!!
