Hey I dint think most people mind helping with a go cart; I certainly don't. The probably coming on mere with "Riddle me this Batman" :eek: and you are the Joker :mad:.

Anyway; you need to figure out what your harness or lack there off is. Given the situation , it should be pretty simple to figure out what wiring is there. I'm suspecting you don't know much about electrical stuff because this should be relatively easy as you really don't need much I suspect.

Once we know what you have we can identify what is missing. Otherwise find someone that can wire a harness from scratch like some of the bobber guys do. I suspect a schematic for what you need could be drawn up in 1-2 hours MAX and it might be 2-3 hours to fab and it would be done.

Off teh top my head you will need:
coils (2) per,
R/R (5)
igniter (6)
fuse box (TBR)
battery (2)
Ignition switch (tbr)
Starter Button (tbr)
does that buggy have lights? Stereo? Air conditioning?

No much else right?

EDIT: numbers in (x) are number of wires per device
TBR to be resolved

That is the wiring diagram I used, I have all the ignition essentials mounted on a plate. Once its running I could easily (I think) add turn signals, lights, all the gauges, basically anything that would be on a motorcycle.

coils (2) per- has them
R/R (5)- has one
igniter (6)- has one
fuse box (TBR) - doesn't have one
battery (2) - used one to try to start
Ignition switch (tbr)- Basically its hot wired to starter button
Starter Button (tbr) Has one
does that buggy have lights? Stereo? Air conditioning? - Anything is possible in future, just focused on getting spark at the moment though

OK start with the igniter; is it wired correctly? Do the outputs go open and short as the motor is turned over. If not check power and ground as well as pickup connections.

With a set of coils, one side hot and the other connected to the Igniter outputs here should be a spark whenever the coils go open. Doesn't matter if there is an R/R or not but you do need +12V juice from a battery.

Get this to work. Igniter and Coils need power.

Once this is done the R/R connections are standard and been described a bazillion time.

Get back after the ignition is sparking.
 
Would I be able to check the ignition out puts the a voltmeter? I hooked up an LED to the wires going to the Ignition Coils, but got nothing.

Use a volt meter first to check the igniter outputs. When the igniter is charging the coils the outputs go to ground so you measure a voltage less than 1V. When the igniter fires the coils it goes open meaning you will measure the ignition voltage (close to 12V). If you see this up and down as you rotate the engine then the igniter is working (with power on). If not check the connections.

After that works hook up the coils , put a spark plug into one of the high tension wires ground the end of the plug and watch it jump the gap. U get here all is connected correctly except timing.
 
Okay, as soon as I get it back from this bum that I thought could help I will do this. Thanks for your detailed instruction. If you have anymore advice, feel free to post, as I greatly appreciate any advice that can be given. So far nobody has been able to help me out.

Get past the ignitor wiring before making it any more complicated.
 
Just incase anyone has been wondering, I got my GS450 Go-Kart back today and am going to begin working on it shortly :)
 
Are there any safety features that would keep it from running such as a clutch interlock or kickstand sensor or ANYTHING that may need to be taken care of?
 
The factory wiring does include a clutch sensor - you should see it on the wiring diagram above. It's labeled as "Starter Disconnect Switch", green/yellow wires. If you just connect the two wires together, it thinks the clutch is always pulled in, and will always start.

A PO put an aftermarket clutch handle on my bike that didn't include a sensor, so I have the connections plugged together in my headlight bucket for this.
 
You say that there is no ignition switch, right? Just "hotwired" to the start button? You still need something that will switch power to the coils and ignitor. The start button just closes the starter solenoid. My guess is you don't have power to where it should be.


Sorry to make it more complicated, but after you get spark here's some other things to look at. If the guy you bought it from didn't know enough about electrical to figure it out, I'd suspect everything else as well.

-There's pod filters on the carbs. Do you know if the carbs have been properly re-jetted for them?
-You may have to go one heat range down in the spark plugs as well. I don't expect that you'll have real great air flow to cool your engine, nor will you be doing the kind of speeds a bike normally would.
-Read up on information on here about carb tuning and doing plug chops. It's pretty important to know if you're running rich or lean, unless you want to learn how to rebuild an engine as well.

These are all things to think about later. Most importantly, get spark first.
 
Thank you Fender Freak for that tidbit of info, I will be sure to do that. And thank you as well Rudy, once I get it running I will be sure that I evaluate the airflow and carb situation.

Do you know how I would go about doing that?
 
Check the circuit where the "engine stop switch" would be. It's the kill switch on bikes, on yours I believe it's orange/white and orange wire. It may have just been permanently wired together if the PO didn't want a kill switch.
 
Okay thank you, another thing I will have to do. Any more from anyone? hahaha

Here's the circuit highlighted. This is all you really need for it to turn over and fire. You may also want to check the other wires that go from the ignitor to the pickup coil, and the white and yellow/blue ones going to the coils. They're pretty easy to follow on the schematic though.

Red = Ignition circuit up to ignitor
Green = Starter circuit

Excuse the sloppiness. Just using MS Paint at work.

No worries. It's kinda my day job. Electrical engineering, not being a genius..... though, maybe that too. :D
 
My brother had something similar to that in the 70's but it had a BSA 441 Victor engine. It overheated and seized in Baja. Be careful about heat.

Yes, I have been reluctant to say that the motor is on a go-kart but you have to admit it's a pretty cool idea.

Also pictures can be found here:

I bought it of ebay from a guy in maryland. And I love in Grantville, PA. Near Harrisburg/Hershey/Lebanon, if anyone has heard of the Hollywood Casino, about a mile away from there.
