Strange Problem any ideas? - Sportbike Addicts

yb929rr · 07-01-2007, 08:22 PM

riding my 929 today. speedo and temp went blank on blank on, etc. tach dropped to zero and engine sounds like stalling. rev it and everything came back. finally it quit. but the pump was still working and had juice. took everything off and saw one ignition coil was lose(#4). took it off and tightened the plug then put the coil back. jump started it(thanks for the push ian) and then the problem went away.
any ideas on what caused this. alternator or starter going? battery is only one year old.
one more thing, i checked my manual and when it wouldn't start the 'starter relay switch' was making a clicking noise.

sounds like you found the problem and fixed it.

Check the harness connection to the back of the cluster.

thanks i'll check it!

If that side is plugged in tight, then check the other end where it connects to the main part of the harness. Also check your battery connections, especially the ground. If all that checks out ok, put a volt meter on the battery. Should read around 14.1-14.3 under revs.

well i had a similar problem check the connection to the charging system had a plug melt on me and when i hit a bump it would die then it would come back and die again when i hit a bump. start at the stator and work your way to the rectefirer(sp) then to the battery. oh and by the way when you have a die battery you should hear the starter relay click because the battery has enough juice to make it work but not enough to turn the starter over

thanks for the good advise. while i had it apart on the roadside. i unplugged and plugged fuses, the plug into the starter relay, and the battery(positive and negative).
it just really had me puzzled. then the rest of the day the starter worked and it ran ok. so maybe i tightened what was loose? i'll go over everything again.

before i set my bike on fire or send it to the shop(depends on how i feel next time i look at it) i thought i'd see if anyone had anymore ideas.
at the neutral switch i'm getting no continuity from the ground wire as the manual states i should. just checked the actual switch and nothing also. changed the switch and the sub-harness leading to it. still nothing from the wire but continuity from the switch. the ground goes to a clutch diode in the fuse box and goes back out to the clutch lever and the starter(both working).
am i going insane or missing something?

When I took my 929 in for the 16k valve adjustment and spark plug change, the mechanic found and replaced 2 out of the 4 ignition coils. They were loose and no longer "snapped" onto the spark plugs. Seems like they just wear out over time. Did they fit snugly when you put them back on the plugs?

in my limited knowledge, wouldn't that just cause those cyclinders w/ lose caps to not fire? it would run terrible but not shut down.
that is something good to keep an eye out for and thanks for the imput.

The dash would not shut off even if the plug wires hanging in the breeze.

Assuming what cakes said checks out... battery/charging system operational and battery connection tight. THEN Check the ground connection to the frame (off the battery) If that was loose or corroded, you would have exactly the problem you described. Dash flashes off, motor still running but running poorly, revs made it run better, then stall and starter clicks, then it runs fine again.

otherwise it could be a loose muffler bearing or maybe too much pressure in your left fork tube

What have you tried to this point? Are the symptoms still the same?

-new stator
-rectifier/regulator

took it out for a test spin same thing.

-right now i got the wire harness out and looking for anything.bike is in pieces.
-took off the connection to the speedo and put i back tight.
-basically did that w/ all connections.

right now i'm to stressed to do anything w/ it really. my mind is beyond boggled.

Know anyone you could swap clusters with just to test? It's starting to sound like possibly a bad ground. Be sure to check ALL ground connections and to make sure no ground(and positive for that matter) wiring is corroded or pinched anywhere along the line. Look close at the insulation, make sure theres no tears or holes, whatever. For the cluster to go blank its loosing main power from somewhere IMO. If you stall or run out of fuel, the cluster is still going to be on cause it runs off the battery. Did you try the volt meter to the battery? Could be a bad cell within the battery. I'm reachin here
