Question KTM 690 Enduro (2012) tachometer not working

Hello all,

I recently replaced my 2012 KTM 690 Enduro that was stolen, with the exact same bike (year, make/model) I found on craigslist. Only 3000 miles on the odometer and looked in perfect condition. Everything worked on the test drive and during the 300 mile drive home yesterday.

I got home yesterday, went to sleep, and this morning when I started it, the tachometer wasn't measuring the RPMs anymore. When I turn the key, it goes through its normal instrument startup procedure where the tachometer needle goes to max and then back down to 0 and the lights go on. But then when I start the engine, the tachometer needle stays at 0. Everything else works with the unit- speedometer, high beam light, FI light, turn signal light, clock, odometer/trip.

All fuses are still good. I've been going through the wiring schematics and exploded view of the engine parts to try to figure out the circuit that measures RPMs and how it interfaces with the computer, but I don't really have experience with tachometers. I've come to the conclusion it's being measured by one of the two sets of wires going into the alternator cover. The other set on the left side of the engine I've deduced to be the gear position sensor.

Also, I posted in the ADVRider thumper forum as well for greater exposure. If it helps to see its replies (if it gets any), it's at advrider.com/index.php?threads/ktm-690-tachometer-stopped-working.1170115/

Please, If anyone that can help me diagnose what's wrong, I'd be very grateful.

Many thanks,

Welcome to the forum Kyle.

I guessing you must have had replies
on you ADVrider post.

I can say that on the 950 SEs, there was a flex circuit in
the dash that developed a break and some lights and
other functions stopped working. Mine didn't have that,
but I remember others did on KTMTalk.
