Intermittent ignition/power cutout

[thogland]

Thought I'd seen something like this but can't find it, either searching or just browsing through posts.

Was on a two-day trip, about 6 hours riding each day. First day, in the middle, I'm riding along, CC set at 65, listening to the ipod, nothing special happening, and everything cut off for a fraction of a second - ignition, audio, CC, even gauges dropped to zero. Then, everything came right back (except CC - had to resume that). Second day, heading home, same thing happened 2x. I think I remember this happening once or twice before, but can't remember for sure.

I thought the suggestion was to check the main fuse at the battery, then if that's OK to check the wiring on the left side of the tank under the fairing. Anyone remember this and have a link to it? Or have any other ideas? I'm going to go pull the battery and clean it and check the fuse, and then pull the left side plastic and check the wiring, but am hoping there might be other ideas.

Thanks everyone!

Update - pulled to main 40a fuse and checked - nice and clean. Pulled the left side plastic off (and wished hateful things on all manufacturers that make these twisted puzzles for us to follow). I can see several wiring connectors, most small and none stretched tight. One big one buried farther in (pretty much behind the aux power connector), looks like it has a red lock on the top, but it doesn't seem overly tight either and none of the wires look loose. 

Thoughts? It'll be heading into the dealer this spring for it's annual, and if there's an issue I'd like to get it addressed. This one includes air filter etc. so they'll be in there anyway.

Faults of this type (intermittent) are difficult to detect, it can be any false contact, cables, relays, damaged cables, including the ignition key harness.

You can also check the contacts and wires of the same red switch found on the right hand grip.

If you don't find anything that causes that failure. As you have to take the motorcycle to your workshop, they can verify with the Triumph tool. There are many possibilities of finding a fault of this type, since you have the option of checking all the contacts, voltages and sensors.

Assuming this is not related to the Ignition Wiring Safety Recall,
you could also check the two plug in connectors at the back of the Instrument Pack.
( Which will involve more cursing to remove more panels).

Thogland - This has happened to me a few times. As you said, it happens when using cruse control, going down the road, minding your own business.

[My theory...] Suddenly the ECU detects something it doesn't like and steps out for a brief second and then it decides life is good and on you go - after resting the cruise control - and thinking 'what the heck was that all about?' It won't happen again for months.

This hasn't happened to me for a long time though and I'm wondering if my battery replacement a couple years back might have been the fix? We all know the TTSE is voltage sensitive.

It has occurred multiple times on mine for a split second and once while the cruise control was set.  I had two separate email cases opened with Triumph USA over the issue and when it went in for the ignition switch wiring recall it had finally resorted to failing to start at any time.  There was voltage everywhere there should have been EXCEPT the starter switch side of the starter relay.  I was able to use a frankenswitch made from two small diameter solid copper electrical wires under the starter voltage side of the relay and go ahead and make the trip I had planned.  Between my emails to Triumph and the dealer making application for a new out of warranty replacement of the ignition switch I'm getting a new one.  I have no idea if they will furnish new lock cylinders for my luggage or not, but I don't really care as long as it will start with the push button when asked, and not go dead at speed, which could be life threatening in highway traffic.  Send the Triumph aftermarket team an email and make them aware of the condition.  It is important that they know about this before they find themselves unexpectedly contacted by some government agency about it.

I have experienced this too, maybe 3 or 4 times since I've owned the bike but not for probably well over a year or two now, I didn't have the cruise control on at the time so I don't think it's got any thing to do with that to be honest.
I'd say that it's just another bug with their system, just like when the USB drive doesn't work after you press the starter motor button sometimes.

A question! On the occasions that you mention, did any of you, the engine stop?
