Hi all.

Bike was fine pulled up turned it off. Went back to start it and starter motor was spinning but not engaging the engine.

bump started it and then rode about 3 miles and got fault code Fault Code 46 on the display.

No fault showing in DIAGNOSTICS on the bike but does show 46 below the speedo.

Error 46 - Vehicle system power supply (Monitor voltage)
Power supply to the FI system relay is not normal
startability = Unable, drivability = Able

Tested battery at home and was @ 11.8v
Took it off and charged it up was @ 12.8v but still same error and spinning starter motor but not turning over.

Took off fuel tank looked at the wires but all appear to be mint!

Clocks were going off when trying to start the bike!!

Erm where do I start

check DC voltage at battery should be around12-14 volts
check resistance at stator should be less than .5 v but check your manual for specifications.
check imput to regulator to make sure its about 14volts

OK Battery Charged @ 12.7v
Tried to turn bike over Error 46 still there - starter spinning not engaging!
Bump started it - error 46 goes away.

Volts check reads 12.4 running at idle
revved it 5k 13.62v and again 14.30v

Set off for a run and stalled the thing in heavy traffic, Still wouldn't start off the Starter so I bump started it again.

Took it for a 12 mile trip.
Got home checked the volts running @ 12.20v
Revved and only got 12.50v?

Stopped the engine and tried to start it and.....

It started? WFT?

Now where do I go from here? NEW Battery or Alternator?

mine did this same thing for a while, replaced the stator, rectifier regulator, and battery, and still nothing, turned out it was as simply as a corroded ground (which you would think i would have checked first) but fixed, and starts every time now.

Need to keep the connectors for the stator and rectifier clean. There is a lot of current that flows through these connectors and if there is the least bit of resistance on the connectors they will over heat and burn up. Especially the connector on the rectifier.

Hey man did you ever figure out the issue? I'm having the same thing happen.
Checked stator - passed test
checked rectifer - passed test
checked battery - passed test
check wires - everything is clean and well connected
Symptoms - Bike starts up fine voltage holds up fine while idling. I rev the bike to 5k voltage goes up for the first time. After I try again it seems to not charge any more it fails... voltage starts dropping and lower each time I rev.
Checked fault code and got - 62 - Powr supply to the FI system relay is not normal. Open circuit in wiring harness. (red/white line) Malfunction in “CHARGING SYSTEM”.

Which grounds should I check?
