690R Irregular Electrical Problem
« on: August 03, 2017, 07:54:29 am »
I have a 2010 model 680R Enduro, also known as the PitBike. 77500km on the clock.

Lately this machine is developing a rather strange habit. At very irregular intervals the whole dash display will started to flash like the disco lights in the old Jacqualenes. The exhaust note sound very different, misfires, backfires etc. Open the throttle and the engine just cut out and die. Then it refuse to start. Sometimes all the lights go dim or dead. Switch the ignition of, wait a minute or two, try again and it starts, all is fine. Maybe a week or two later the same again.

This habit of it caused for some fun and games in the traffic.

New battery was installed about two months ago. I commute with the bike to work and back all 8km of it every day, plus fooling around over weekends.

Any one out there experience something simmilar and what could be the prognoses?

Regards

690 has 2 frame earths.  The one at the steering neck is usually to blame if the dash starts flickering.

OK, as suggested by Bill the Bong, I start to strip the wiring and check all the earthing points. All was fine. Next step, get hold of a can or two of contact cleaner. Proceed to try to undo all electrical connections and plugs, what a mission (I have drowned the bike a couple of years ago) and spray it with the cleaner.

No change, nada, nothing. Still the same.

As last resort, took the bike to Trax KTM. Result - it is the faarkin voltage regulator. While the bike is idling, the charging voltage is 13,5 - 14Volt. As soon as you touch the throttle the voltage jump up to 18 - 20 Volt. Then everything went apeshit. The bike's blikbrain's tor bliksemed of the cork.

Bloody modern computorised control systems and fuel injected................. oh where is the days of carburetor, points & plugs

Sorry.  Mine failed as well. Caused the bike to stall when the voltage spiked.

Hmmn worse than I thought.
Got the bike back and it was fine for about 30km of riding, then other shite started. Receiving this letter 9 morse code (- - - - .) message from the FI lamp code.
End result, the base of the fuel pump relay were melted (could be the result of the voltage regulator over voltage ? maybe ?) and the fuel pump decided that is it, i am going on slow strike.

Damn there goes my holiday moola
