problem with your volt pen is that it will indicate voltage (they dont sense current) present but wont tell you how much. voltage presence indicators will pick up from 10-415v. Not dead usefull in determining wether or not you have sufficcient voltage or not..... but double check that kill switch wire and prove that it is not earthed somwhere between coil and switch. all the coil does is store lots of voltages and release them when told by the igniter, thus if igniter circuit shorted (kill switch) or not enuff voltage being introduced to coil means they dont work.....all this is based on the statment that your coils are PROVEN good not assumed good. proper test equipment can save a lot of time (but ussually costs a lot of money). And for goodness sakes.... just coz its free does not make it good.

Yes its under the frame, but the ground is good it read good with the meter.
i went back to the bike today as i bought a fluke volt alert pen and it detected a current (when i kicked) on the red wire from the stator all the way to the coil but not after, look like the current dies after the cdi on both of my cdi's which i know one is good and one sparks confirmed was good so i now know that a current does move all the way to the coil but im not sure if i should even be seeing anything after it.
im attaching pics of the magneto flywheel throw out your ideas guys.

just looking at your pics again. couple of questions: why is the violet wire grounded on the grounding ring? i thought violet was the hot wire to the the tail light? also, the box in your pic above the ring is not the cdi, it is the voltage regulator. the cdi is the coil, and is grounded using the black wire coming from it. is this the case?
who can tell me why my light has no power to the lead wire, yet is still running. any info would be great.
Either there really is magic in the world or your lite runs with your motor but has no voltage when motor not running.
Maybe you measured the wrong wire? Maybe you gonna be real rich with your new found magical no power lite. Bit more info would be helpful...... how and where are you testing?

sorry what i meant to say is with engine running, no volts on the front light wire. I guess with no power on other wires,including rear light. is it the stator, can I rewind it my self,or any one I could ship to. thanks for responce..

The stator has 2 coils one for the lights and one for the rest. The lighting coil puts out ac voltage, you will have to be on the ac scale to check it, and of course the motor will have to be running. The other coil produces dc current.
Ned elluded that he thought the violet wire is for the tail lights. If this is grounded it will take down the lighting coil to zero volts. I dont know if this will damage the lighting coil but chances are it will. Hopefully the circuit has a fuse in it.

ken, don't be confused about our hijacker "501baby" and the original thread person "fe501". the pics were from the latter. mr 501baby has just jumped on the other guys bandwagon and hasn't even told us anything about the model of the bike in question. but thru the power of FM, we shall be able to solve his problem. 8)

would a bad voltage regulator cause my problem of no spark?? how can i test it?

No it wouldn't. You can disconnect it and still have spark.
You only need the red, black & green connected to the CDI and open cct the kill switch (orange I think).

ok great so i know thats not the problem, what about the ground wire on the cdi and on the stator does that need to be hooked up to the frame?
