Electronics » Start/Stop button stuck

Not actually an “electronic” problem.

But it was certainly a NoGo situation.

Yesterday I was giving the bike a once over before my first ride of the year.

Luckily not to a planned outing or appointment.

Last year I noticed both Left and Right rocker switches were getting a bit “notchy”.

That’s what almost 8 years and 40K miles gets you.

Anyone riding a young bike can look away now

I gave the switches a squirt of specially purchased Switch Cleaner and the LH info switch was much improved.

I wasn’t trying to start the engine at all, using my dumb service key to let me do everything but fire up and the Stop/Start button locked solid.

Now that would be inconvenient outside a hotel far, far away.

A quick read of the manual told me which screws to look for. Importantly for the LH switch “Do Not Remove The Small Screw”

But the RH switch needs a petite 8 Torx screwdriver and nimble fingers to open up the switch housing. Disconnect 2 miniature multi-plugs remove 3 more tiny Torx screws to dismantle the switch.

Or should I say 4 switches plus throttle cable of course.

Long story short - I could have thrown the small spring loaded pawl away and tried living with a “floppy” Stop/Start button, but went for Plan B by filing the point more rounded and reassembled everything.

Good to go.

The 4 button assembly is a wonder of science squeezed into a small space. Looks hermetically sealed to beat the weather.

Every day a school day (today’s unexpected lesson was an electric lawn raker gearbox service but that’s another story)

ps - the bike did fire up and ride ok. Tested both Start/Stop buttons when I returned close to home.

pps - the almost 8 year old original battery fired up as it always has done after months winter hibernating on an Optimiser charger

Nice pictures of the internal details. Must help several people that will probably get similar problems. Just a matter of that T8 driver being available when needed.
I had a zoom lens that jammed up a few years back in Belgium. Replaced it with a secondhand one. But while recovering from Covid and bored stiff I managed to strip the jammed lens and dug deep enough to find just a loose screw and its all good now. just the patience needed on these jobs.
