Author Topic: CR ignition question (Read 13840 times)

So, I have a 2001 CR ignition that has never worked. I mean it has massive kickback, and has never fired up. My bike runs on the stock ignition just fine and has no problems. I have replaced everything from the stator windings from Ricky stator to another CDI, flywheel a brand new coil and plug, good grounds yada yada yada. The only thing I have not replaced is the the actual wire harness and the pick up. Everything has continuity and ohms out in spec. Now here is the thing that is really baffling me. If you look at the CR250 ignition wiring diagram from Honda that is posted in the Tech section it shows that there are 2 grounds that join together from the coil and stator plate and then to the plug for the cdi. Mine is different and looks to be all factory connections. My ground from the stator plate joins the green/white from the pick up and then goes to the plug with out ever connecting to the ground for the coil. This gives the pickup a direct path to ground and I don't know if it is correct. I need to know if the Honda manual is wrong or if I have some sort of ******* child? And should I just try and disconnect the stator ground from the pickup and connect it to the coil ground like the manual shows? Here are a couple of picks.

Took a close up pic of my 2001. Seems to look different. Was your rebuilt?

is your timing correct? what adapter plate are you using.

The stator itself is a replacement from Ricky Stator, I still have the original. I have not degreed the motor with a timing wheel yet. The adaptor plate was purchased from ebay and advertised as an ESR plate. So, any ideas on what is the correct wiring config for the grounds?

The green wire and the green wire with white stripe both go to separate prongs on the CDI as seen in pic. The green and white wire goes to the stator and the green one goes to the ground on the coil. I am not seeing them hooked together on my stock harness but they may be back by the stator

Puma, could you do me favor and unhook your plug from the cdi and then tell me if you have continuity from the green/white at the plug to the ground wire at the stator. I had to cut the cover off the wiring harness to find out that the ground from the stator was connected to the green/white from the pickup.

you should have two grounds. one for the coil and one is for the harness

I do have 2 grounds. And according to the Honda manual those 2 grounds should connect to each other in the harness and then proceed to the cdi plug. My two grounds do not connect to each other. I am trying to find out if the manual is wrong or is it my harness.

I would if I could find the ohm meter. Don't know where it went.

Did someone float the ground in the harness for dc lighting?

I would hope not seeing all 8 poles are for spark, the cr doesnt have low voltage auxillarly coils for lighting only high voltage for spark

Oh yea I forgot the cr is a whole system I was thinking it tied into oem chassis brain fart...

Try running an additional ground from the coil to another spot on the frame

Already tried that too.

I am pretty sure the green white from the pickup coil should not be grounded in any way it will more than likely work once you remove the stator ground from that.
