CR ignition question

[C-Leigh Racing]

Sure would be nice, if ol Teamgeeks6 from Mac Dizzy was still around, now he knowed somethin bout sparking.

So, I tried removing the ground from the green/white wire and then connecting the ground like the manual shows and now it no long kicks back because there is no spark! And just to make my blood pressure go up a little more I found another hidden surprise in the harness wrapped in some nice black vinyl shrink tube.

That is the two wires from the pickup, so someone has either replaced the wires themselves or the pickup unit and now I am questioning if it is even the correct one for this stator since it has a green/red wire. Does anyone know where I could get just a known working pickup? Also, if someone running a cr ignition would be kind enough to unplug their cdi and check for continuity between the green/white wire at the plug and their ground, I would be most gracious.

I am still pretty sure that the pickup coil wires do not go to  ground, what did you do with the green wire that you removed from the green/white pickup wire ?

[rsss396]

I looked at a wiring diagram for the cr ignition and the green/white from the pickup coil does NOT go to ground they are isolated and go directly back to the CDI

The Green wire from the stator goes to the green wire that connects to the ignition coil

I connected the ground from the stator to the ground from the coil like the manual shows.

[rsss396]

that coil and stator green wire should also go to the cdi, is that how you have done it?

Yes that is how I have it now.

Hey  Wiley,
does look like your wiring needs to be looked closely. I have  few systems here and have also built a couple using parts from the CR125 stator assembles. The joining of the stator ground (Green ) and the pickup (green n Yellow ) is correct. The ground from the coil goes directly to the CDI. look closely at Puma' system. yours should look like his.
 The one thing that has not been talked about is your flywheel. The flywheel must match the CDI. What are the numbers and letters on the CDI and Flywheel?
Take note of the KZ3V on puma's CDI and stator plate. The flywheel should also have KZ3V if 2001. KZ3T if 2000
  The timing will b off if the flywheel is not a 2000 or 2001.
Hope this helps.

Good job slowride! I just looked at one of my stators and you are correct that the stator solid green wire and the pickup coil grn/white wire have the same continuity  and the coils green wire to the coil goes solely to the cdi. That is odd that they wired that that way especially with 2 different color coded wires blending together
and I question what schematic I was reading I found on Google must have been a earlier year 250r even though I searched the for a 01

and yes the cr125 flywheel is way off timing wise

Thanks Slowride250R,
I talked to Rickystator and they told me the same thing about the stator ground and said it was common for Honda to do that. The green/white wire from the pickup for the Honda usually ends up being a ground and this means that the wiring schematic in the Honda manual is wrong as well. (Doesn't surprise me at all). It is just my luck that I seem to have a one off problem and a trusted source for info never updated their changes. I have both years for my choice of flywheels. I was under the belief that both the 2000 and 2001 used the same flywheels, just different part #s. I also have both year CDI's as well. So I can match everything by year and go from there. I will keep on updating as I go.

97-01 cr250 flywheels can interchange but the cr125 does not

Thanks rsss396,
Just as an FYI for everyone Rickystator sells just the pickups alone for $39. Also all the Honda wiring schematics for the 125, 250, and 500 all show the stator ground connecting to the coil ground. So most likely these drawings are just reused over and over and either not been updated or the cr250 harness is just the red headed step child of the group. You can find some schematic's on Service Honda's website for the cr500 unit they offer and the diagram is pretty much the same as the 250.

Update time, she runs!!! Thanks to all who helped and now I have found a new possible cause for kickback. I gotta really thank Ricky Stator for their help. As soon as I told him what I found and what was going on he had the answer immediately. Before I give the cause of all my headaches, I want to hear some of your guesses.

Sheared flywheel key?

Sheared flywheel key?

No, that would be to easy.
