more than one V7/9 ignition switch has failed. broken wire on the back.
I bet you can get a finger up there and wiggle a tiny bit while running.
Thanks for the responses.In the parking lot at work, I checked the battery connections, which were good. I also checked the ignition switch (as much as I could). I also checked the side-stand switch. All seemed good. I rode it home with no issues, but I'm going to have to do further investigations now.
Will the engine stop on your bike if you disconnect the battery while it’s running at well above idle ?
Recheck your ground strap to the frame. Crack it loose then retighten.
I eventually realised it always happened doing slow r/h turns like tight roundabouts or pulling into my drive way. I traced it to a loose ignition switch connector on the back of the switch which would break contact when the steering was turned with the wiring moving.
but if the whole bike shuts down then your problem should be between the battery and ignition switch inclusive, or the switch and the main fuse panel inclusive.
Its a fuel injected bike. Couldn't it be an intermittent pump, failing pressure regulator, timing sensors?. I'm with MUZZ. This intermittent stuff sucks. Works fine one day and not the next. Basic scientific principle; you can't prove a negative. You could 'fix' a dozen things and go for a perfect 100 mile ride. Next day it won't start. Crap!Patrick HayesFremont CA
I have a Stelvio that did exactly the same a couple of years ago, it was a break in one of the wires from the ignition switch to the ECU. Had broken inside the insulation where the harness from the switch routed round the headstock and would at random switch everything off exactly like turning the ignition off. Cut the sleeving off the harness and pulled/wiggled each wire until I could get a permanent fault then cut/spliced new wire in. Works OK since then.
Milosh, you don't actually say if the whole dash stayed dark, or whether any lights came on when the bike died.
Update for those interested.I talked with Enzo at Cadre. He suggested I try a few things first, which I did this afternoon.1. Check the main fuse. I checked the main fuse by eye and by continuity. Good.2. Make sure the battery terminals are tight with a 10mm wrench. Did that. I had previously attached them with just the Philips.3. Inspect the main wire connection to the ECU on the throttle body. That seemed tight and pressing it on further made no movement.4. Check the kill switch on the handlebar. It works. Noteably, the kill switch allows the lights to stay on, but in my instance everything goes out.5. Check the ignition switch. It works. But I have an intermittent problem!So now I'm at a loss as to what to do next. I may get the GuzziDiag and see what that does. But because it's intermittent, it may not show up.
What does this mean? Did you start the bike and grab the wiring to the ignition switch and give it a good shake around and also turn the handlebars full lock both directions? You probably dont even need the engine running for this check as the symptoms you have described are main power related.
Cadre are good folks to help you like that.
That's exactly what I did.
The dash went dark. No lights. No hazards. Nothing. That was the scary part. I've had bikes stall and been able to restart them. This was different.
