Im making a new thread for future HISS fellows troubleshooting their bikes.
So the deal is: I bought this 2002 954rr (turbod) from a guy who trashed the engine abusing it over the limit.
He then rebuilded the engine from a donor bike. Whole upstairs was replaced leaving the bottom end original.
(valve had hitted piston when camchain tensioner(?) broke.
Long story short: He couldn't get the bike start after the rebuild due to a missing spark and then sold it for me cheap.
I've been troubleshooting this machine now a week and it starts to look like the ecm, or atleast cdi unit of it has been burned.
Im getting straight 12-13 volts from battery to the coils but once I crank it no secondary voltage is seen. Should be around 100v:ish what i've read on the repair manual.
I have checked both the cam sensor and crankshaft sensor and they give approx 0.8-1.4 volts when cranking. And give that same voltage to ecm (back probed)
Replacing them both tomorrow with spare parts to be sure.
Only thing i'm now unsure of is this infamous "pink wire" with zener diode which seems to be bothering us version bikes.
In european version we don't have the pink wire coming from ignition but from HISS system.
Im getting voltage readings from it like 0.4v when power is on and 2-3v when cranking.
Could some friendly soul who has a running bike with HISS system check this voltage for me?
Is it supposed to be around that figure?
I've been readin that in us bikes it requires 9v from the pink wire to ignite the spark. But i'm flabbergasted now.
Bike operates just fine otherwise. Fuel pump primes, so it's not the bank sensor. gauges work. sidestand, neutral and clutch switches work fine and have continuity to the ecm. clutch diode checked good.
It just seems to be lacking the 100v power from coils. I checked wires from coils to ecm and they all have continuity!
I guess next thing is to replace the whole ecm with ignition and HISS sensor and keys
