K 75 weirdness
Intermittent gremlins are such a bitch. Sixth sense is guessing an
engine electric issue.
At the point I do NOT know where to go next ! Maybe it's time to buy a
new GS and be done with it. LOL
Two months ago, I experienced some intermittent weirdness on my K 75.
Engine would NOT rev over 3K without stumbling/stalling. Limped into a
service plaza, dumped the fuel suspecting contaminated gas,refilled
with fresh petrol, NO change.
Out of desperation, I re-inserted the ECU brain plug, BINGO, fired up,
away we go into the sunset. R&R the fuel filter upon return to the
house,new spark plugs,fuel pump,coil connections inspection, ignition &
kill switches seem OK.
Ran perfect, over 2800 miles __________ till this afternoon. :-(
ECU was un-clipped and clipped back in for the second time, ____ ball
game back on. Why is a mystery as it's NOT loose,corroded,etc. In the
garage, damn thing purrs like a kitten,unable to produce any weirdness,
It is possible the TPS is sending a funky signal to the ECU to cut-off
to avoid over driving the engine ?
How long should a TPS last ?
Should I suspect a Halls Effect Sensor slowly going south ?
How long/mileage should a HES last ?
I seem to remember someone posting the electrical values of the TPS a
couple years back. Could you please post them again.
Wish I had a spare ECU to swap but they rarely fail. NO idea on how to
test one anyway.
1994 K 75 standard 253,000 miles (data point)
order of flailing on the slate for Monday
#1 re-check the coil connections
#2 ignition wires ohm readings
#3 visual & electrical inspection of the TPS
#4 Jeff Dunkle's HES hairdryer test
don't you use some kind of anti thermal paste on the backside snobum ?
Anything else I'm missing here ? THANX
