I replaced my kickstand switch recently with the used one from ebay. Not sure if that resolved my intermittent problem when the engine dies for a fraction of a second - need to ride more.
However, I had my old kickstand switch, and I just wanted to know how the heck it works and what's the potential for a failure. It's sealed pretty good with some sort of epoxy glue. So, long story short, I took it apart, breaking whatever was in the epoxy layer - some small electronic circuit came out, a small resistor and a couple of other things.
After scratching my head for a while, I figured out how the thing works. So, here is the deal.
When the switch is being pressed/released, it simply moves a small magnet which stays in it's own mechanical compartment. The electronic part is adjacent to the magnet, but is completely separated with a plalstic piece. Entire electronic portion is sealed with epoxy or something similar, and consists of the magnetic switch and a 28k Ohm resistor on a small circuit board.
The magnetic switch is pretty small - the size of a small resistor, and should be very reliable as it has it's own small contacts sealed within the outer body. The internal contacts are probably a few microns away from each other, and when the magnetic field is present, they close the circuit reporting to the ECU 28k Ohm resistance as opposed to the circuit being open. Oh, yeah, the metal body of the switch is non-magnetic - seems to be an aluminum.
This seems to be a very rilable design (and at least partially explains still outrageous price). I just can't image this thing to fail.
On my last short ride nothing bad happened while on my previous short ride, I think the engine cut off twice.
I am somewhat convinced the kickstand switch is the troublemaker. About a week prior to my recent track day, the bike was cutting off numerous times during a ride. I glued a small piece of metal to the kickstand where it pushes the switch to force the switch pin to go slightly deeper into the switch. The problem disappeared. I rode 160 miles to the track, about 150 miles on the track, and about 160 miles back home without any issues - altogether close to 500 miles. Only, at the end of my trip close to home I felt (maybe) it happened again. So, I ordered one from ebay and replaced it. But, I think it happened a few more times on my recent rides. Don't know, maybe I just rolled the throttle off and I am imagining things. Need to do more riding.
