Gutted harness issue

onequicktang · December 18th, 2014, 08:34 AM

Ok I am putting a 2001 ninja 250 engine into a go kart. Im trying to gut the harness down to run and charge! Have power to the coils but not getting spark. Cant seem to find a diagram with the same colors I have in my harness to the cdi. Can anyone help?

Well I give it a shot, with some pictures, and pdfs'

Hope this helps you out.

Thanks. Do I need the resistor for the gray wire? could that be my problem?

No clue, maybe someone else will know for sure

Welcome, Adam!

While I have no direct knowledge about it, I've read that the resistor has to be in the circuit for the engine to run: some sort of theft deterrent (most hotwire thieves don't know about needing the resistor). If I'm incorrect, a more knowledgeable member will chime in.

You need gray. Ign 12v + 100 ohm resistor to gray wire to cdi turns it on to give spark

dcj13 · December 18th, 2014, 06:22 PM

There you have it! You need a 100 ohm resistor rated at 180 milliamps or more (and 14 or so volts or more).

First three color stripes should be brown/black/brown. If there's a 4th stripe, it ought to be brown, red, gold, or silver (in that order of preference).

Or he could use some the OEM ignition switch too, nice to have a key on a toy like that.

dcj13 · December 18th, 2014, 09:35 PM

A key for a go-cart? Heresy!

A go-cart with a 250cc motorcycle engine LOL, better watch where he parks it.

thanks everyone. I do have the ignition switch for it. is there a way I can wire to only use what I want and get spark?

Just follow the wiring schematics, and start simple, and work your way up

The schematics I have which are supposed to be for an 01 have some different colors then my harness.

You've never hot wired a car before?

Okay time to use that multimeter, power goes in, power out to the gray wire, or run a continuity check, key in run position, one lead on the gray, then start hunting til you have reading.

Also if there are differences between schematic and yours, you can easily find them out with same procedure.

Good luck mate

It's not as hard as people make it out to be, but patience will be your best tool, when doing this, take your time, if you get worked up, take a break.

Remember it's a inanimate object, it has no feelings, or need to piss you off, it's just there.

Been there many times, just remember your final goal, and that usually calms me down.

Ya for sure. Just frustrating to know its all wired right and still not working, then finding out its prob because of a 2 dollar resistor. lol

True, but you got it figured out now.

Can't wait to see this go-cart, and a how-to write up maybe?

Yes... hopefully. I will draw up my harness once complete so nobody else has to go threw the pain I did. lol
