EX250J is 2008+ new-gen model with single-plug ignitor
Hi
We are still having troubles sorting the electrical system on our Ninja engine that has been fitted to an off roader. The Sparky is having a challenge with the wiring diagram and can’t find where Grey and Green/black wires go from the igniter. He assures me he has bypassed the anti-theft part of the wiring. Everything is working except getting a spark at the plugs |

I'm having the same problem. It seems no one, so far, knows how to wire that. FYI, I was told you don't need any of the diodes because they were part of the anti-theft feature. I'm building a race car so I only need ignition and charging wiring.

From the schematic I'd say the diodes are for the safety switches. The 150 ohm resistor in the grey wire from the ignition switch to the ignition module is the anti-theft device. I asked you about that resistor in your thread, but you haven't answered yet.

Haven't tried the resistor. I'm going to get a whole harness, then cut off what I don't need. In the end, that will be easier.

Thanks Jim, I may go with the factory key switch too. I've completly wired two hot rods and several vacuum tube guitar amplifiers and never had so many questions as I've had with this project. It's all good though. It's not like I'm trying to trouble shoot the Large Hadron Collider. I still can't believe there isn't a simple ignition schematic out there somewhere. Thanks again.

I've build some tube amps myself. Are you on any of the guitar boards? |

Thanks Jim. I've seen some of those schematics elsewhere, and some are new to me
and one of them will be quite helpful. I'm in Prescott, AZ and the "gokart" project is in Bozeman, MT where my son lives. We worked on it last week and my son will continue to work on it till the Spring when I'll go back and we hopefully will get it running. P.S. I'm not on any guitar boards. I've got too many projects/hobbies already. I am kind of an old guitar equipment nerd. I've got pics of the gokart, if interested. |

Fixed the Problem
After sitting with the Sparky for 12 month I picked up the go cart and gave it to our apprentice at work who had to finish a wiring module for his Apprenticeship.
Within a couple of days one of the mechanics found the issue, the key switch needed to be included in the wiring as it has an anti theft part in it. All go now |

Yes, that's the resistor I mentioned above.

Hi Triple,
I know, I took your info from this thread to him and a few days later told me he checked that out but wasn't the issue. |
