Infrequent cutting out and magical recovery

[MFD]

I stuffed a bit of wire into the SS- wire at the ignition connector and went out for a couple more test rides.

Bike stubbornly refused to die on the first run, then started acting up on the second run. Confirmed ground connection at the ignition switch connector and not ECU when dead, furthermore, I measured 0.5v between the battery positive and switched ECU ground, as well as the ignition connector with ignition off, confirming the path from that connector to the immobiliser is sound.

Now I'm just debating if its worth the effort of getting some security torx bits to take the immobiliser apart in search of failed solder joints, blown caps, etc... or just ripping the thing out.

EDIT: After it started acting up, I shorted the ECU switched ground to permanent ground, no more drama for the rest of the way home.

If you've confirmed you've got ground coming out of the ignition you'll have to check if you've got it going into the alarm and if you've got continuity between the alarm and the ignitor. I've never had an alarm on a bike so I've no experience of them but I think all they do to immobilise the bike is they stop the switched ground getting to the ignitor so that stops spark and they stop the switched ground between the starter button and the cut-off relay so that stops the starter motor turning over. Your starter is turning over when you press the start button so that part of the alarm is working so that might point more towards the alarm is actually working but there's a break in a wire. But I guess it's possible that something has failed in the alarm that only affects the ground to the ignitor and not the ground between the starter button and the cut-off relay

I cut out the immobiliser and all of its tendrils today, then went out for an hour or so without any issues. So hopefully thats the end of this saga!

Seemed like it was cutting after a short ride before. If you rode for an hour with no problems it's probably good now. Too bad we won't know if it was the immobiliser or the wiring! As far as sagas go that wasn't too bad. You should have a look at Red98's stutter thread for a real saga :lol http://foc-u.co.uk/index.php/topic,2066....l#msg15672
