for the life of me I can not figure it out, the plug that goes to the coil/spark plug gets powe, but it wont spark anyone know what sensors to check that cut spark????

 

have you tried checkin or swappin cdi, stator, pulse generator, or check bad connections.
Pulse generator i think is the cam position sensor/camshaft sensor/pick up

 

get a service book, go through the troubleshooting section so you dont waste your time. No spark, I would guess stator, or possibly ignition coils.

 

ive checked all the connections, gone throo all the **** iiin the service manuel

 

& it sonly a 10 thgousand mile motor

 

here's the service mnaul link

didn't know u looked through the service manual already....scratch that

 

clutch or sidestand ignition cut-out?
tip over switch?

Any time the ignition key is ON, you should have power through the coils, as you've noticed. Power comes through the ignition switch and fuse and kill switch to the coils. The ignition unit is the ground for the coils. The ignition box will just have power transistors or silicon control rectifiers that are switched ON when the ignition is ON, and they get turned OFF when they get a signal from the pulser coil or crank angle sensor. The transistors ground the coils and they work just like ignition points, except they are solid state electronic devices. When one transistor or SCR is turned OFF, you get a spark from one coil.

But your engine control unit probably needs certain enabling signals to allow the engine to run, like it will have a logic circuit that allows the engine to start and run in neutral with the side stand down so you can warm up the engine while putting your helmet and gloves on. But, if you put the transmission in gear while the sidestand is down, the logic circuit will probably switch the ECU off and the engine will stop running.

Typically the ECU will enable the fuel pump to run when it gets a signal from the pulser coil or crank angle sensor that the engine is running or being cranked by the starter. Is your fuel pump priming?

The ECU will need an injector timing signal before it gets a spark timing, so you may have pulser coils as well as crank angle or cam sensors.

Also,the pulser wires could be damaged. the pulser is what tells the cdi when to fire.if not that it could be the side stand switch and u can test that down on the side stand were the wires come out and do a continuity test. u should get a reading when the switch is activated.

 

check 12VDC at coils
then .5 VAC output from pickup while cranking motor ( tests signal coil)
then check for VDC interupt at green conection on each coil (basically signal should fluctuate when cranking motor) tests ecu is doing its job

now if the ecu is recieving signal from pickup but not giving it to the coils then we have two avenues to check 1. bad ecu 2. bad ground to ecu.

 

mine did that a couple of months ago. BAD ECU.! no spark...if I remember right, the fuel pump still kicked on. Definately a pain. luckily, I had a spare.

the fuel pump turns on, and theres power to the plug that goes to the coil but tit doesnt fluctuate, and theres no power where the spark plug goes, im just using a test light tho not a multimeter

 

and it keeps givin the the error code of 9 which is the ait sensor which would not prevent the bike from starting

 

did you take anything aprt before the problem started? What happend.

 

hit up MR RYAN SMITH. He's the go/to guy when it comes to 929's!

good luck, Paw Paw

 

yea i had it completely apart frame & everything off, then when i ou tit together, it wouldnt start ive taken it apart & checked everything out about 10 times and i cant find anything outta place

 

did you plug the ait into the cam sensor? Cant remember the exact wire length but the sensors are in the same area. You might want to get a cheap mutimeter, would take about 5 steps to find the problem. 20 bucks at sears should get you a basic one, then your just gonna test a few grounds at the ecm, ac output on your sensors, and resistance readings between everything.

 

how do I check all that?

 

i checked wheer the spark plug plugs in & its gettin 12 volts, but still no spark what the crappppppppp
