That has got to be it Alley,,,if there is no signal when it's on theachine but has when off the machine it might just be a wonky winding ,, works intermittant

Read this whole thread and did anyone look at the wiring diagram? B/W is trigger coil wire, no problem but can you say B/W also goes to engine kill switch? Has anyone mentioned see if the engine kill switch is in the run position and see if it's shorting out the pulse coil to the CDI because it's grounded out or the kill switch is stuck in the closed position? This scooters engine kill switch is on the pulse coil wire, not going directly to the CDI.
Also why would anyone put a AC type stator system on a DC type scooter? If nothing else the DC style stator will be stronger on charging because it has 8 full coils dedicated to charging instead of 7 and a AC feed to the CDI.
If all the parts are new and good and you have no spark then you've got a wiring or kill switch issue.

Hey JR, thanks for your input. I've considered those same things wrt the kill switches; and there are 2. By simply disconnecting the stator and pickup coil wiring from the main harness and checking for voltage/signal while cranking, have we not eliminated the kill switches as a failure point? I did replace those switches with new pieces from the manufacturer and tested them with a voltmeter though just in case.

If so then if you have no voltage on the pulse coil with it unhooked then it's bad. Remember it will send a signal with as little as .05 VAC.

Ok, so one of us forgot to keep our fingers crossed:)
New pickup coil and stator installed and still no spark.. Can you guys help me further explore the wiring and grounding out of the CDI that JR mentioned? I'm obviously not understanding the diagram or how to test the circuits properly.
Thank you for your help so far. I'm confident I'll get it figured out sooner than later with your help!

Progress.. I completely bypassed the 2 cutoff switches and got a spark for the first time ever. Obviously the fault is somewhere in the wiring. Buggy actually ran for a few seconds with a shot of carb cleaner to it..
Now I need a plumbing diagram to see if I put this thing back together properly. Little history; when I got it , it was a pile of parts...

Thank you for your help so far. I'm confident I'll get it figured out sooner than later with your help! Your CDI pins don't look properly seated and look like they may be pushed out of their plug.... Look at the red insulator boot on the pins.... Only your black wire looks like it's seated correctly... These pins push out of the plugs very easy... Try this, un-hook your CDI plug and push on each wire into the plug... Try and listen for a "click"... These pins have locking tabs and if they get unlocked, when you plug into your CDI, it just moves the PIN back into plug, not into the socket and making connection like it should... This has happened to me before... Push the pins back in and if you have a hot glue gun, put a little dab on the top hold it in place  I wanted to clarify..... I'm not meaning to "hot glue the plug into the socket". I'm suggesting make sure the pins are seated in plug firmly and all the way, then put a little dab of hot glue back where the red insulator boot is.. It will insulate, the insulator plug and hold it in place.... |

And now I've blown the fuse and starter relay... Gotta love it..

Are you sure the Solenoid went bad? If the fuse blew no juice to the solenoid or anything. What did you do to cause the fuse to blow?

Troubleshooting the electric choke because it wouldn't keep running, I plugged it into the wrong connector and blew the fuse. I'm out of those little glass fuses, so I'm going to try a 15amp blade type as soon as I can run down the road to Walmart or auto parts store. With the fuse blown, should it still allow the starter to crank if I short the relay terminals? Mine won't..

Guess it was just the fuse, wants to crank again now with a 15 amp ATC fuse wired in.
So on to the next question.. It will crank with starter fluid but not keep running. I can't say the entire carb is clean, but I did replace the main jet. The fuel line seems to be clear as well from the vacuum diaphragm at the tank to the carb and it does flow to the carb while cranking/starting with starter fluid.

If it tries to start with carb cleaner shot into it then your not getting fuel into the engine.
Take your carb off and soak it in acetone and then make 100% sure every single orifice is totally clean.
EDIT:
If you cleaned the carb and you're still getting the same problem, but it tries to run with the spray carb cleaner, then you have crud in the tank or in the lines. Replace your fuel lines. Remove the tank and clean the snot out of it. Put everything back and add fresh fuel. Remember to change the fuel filter also.

The lines seem to be flowing fine. I pulled the fuel line directly to the carb out while it was cranking and it began leaking gas out the line, so I think the problem lies in the carb..
Thank you for the cleaning advice, I'll get on that next...

Make sure you have the AIR FILTER ON otherwise it is sucking in to much air, what your running into is NOT ENOUGH fuel is why you have to spray starter fluid for it to fire. Turn the Fuel ratio mixture screw clockwise until it bottoms out then turn it out 2 1/2 turns and see if it will start with that. If still nothing then The PILOT JET and passage and tiny PILOT JET OUTLETS are clogged by the butterfly. Get a SPRAY CAN OF CARB CLEANER they come with a thin straw. Clean out the Pilot Jet and then CLEAN OUT the pilot jet passage and you should see spray coming out by the butterfly. Alleyoop  |
