I can’t get fire to the spark plug. | If the ignition module does test out alright then the problem could still be in the pick-up coil/stator, (it can be tested using an ohm meter by dis-connecting the wire connector from the pick-up coil/stator and the ohm reading between the two wires from the pick-up coil/stator should be between 500 and 1500 ohm's, and both of the wires from the pick-up coil/stator should show … See our stator collection for a match on your stator. This quad arrived at my shop blowing fuses as soon as battery hooked up. So you end up with a reading of around 0.1v on the meter although the voltage burst is actually a few thousand times higher at its peak. i pulled the plug out and it doesnt have a terminal nut on it, its a ngkcr7hsa i replcaced the stock one around a year ago, and was running fine, i dont remember if it had a terminal nut and if i am having an issue because of this missing, the ngk doesnt seem to want to stay clipped in the boot as i tried to plug the ngk into the boot with the plug out of the motor. 3. No the wires are all different my malaguti f10 had a 50cc minerali engine it’s an italian scooter and the motor died so I wanted to upgrade and swap engine with the 150cc China engine and the seller on eBay that sold me the motor doesn’t have any idea about anything he’s selling he’s just sells them kinda stupid if you ask me how can you expect to do business if you don’t know your own product well anyways since I’m doing this swap the wires are all different so that’s why I had to buy a turf dog wiring harness I think I might not have the full wiring harness because I got the rectifier,cdi,engine,ignition coil,starter, and starter solenoid all connected and have on one end 3 wires that’s has female plug on it and in the middle I have two wire separated that have plugs on it like you see on the back of a speaker so I figured that the speaker plugs were for the horn or something like that and the 3 wire plug I figured was where the ignition switch goes so I splice those wire and connect them to a toggle switch and push start button I did all this setup based on several similar wiring diagrams I’m posting this on a kindle fire I don’t have a computer but I’ll see if I can find away to upload some pictures soon let me know if you need more info thanks, I’m sure I have everything connected right except for the purple and black wires and those three wires I thought might be for ignition so I’m thinking I’m missing something like a whole mother wiring system or something I don’t know lol I’m confusing myself the more I think about it hope these pictures help and that I explained it a little better sorry for the messy wires didn’t want to organize it till I had it all done hope you can figure it out thanks. I wonder if my wiring is not typical and I somehow damaged the new CDI. This current is stored in a capacitor within the CDI unit. Has anyone seen this problem?

Can you tell me what this box is and will it keep the scooter from firing? Based on that information I thought the stator and pick up sensor were OK I re-connected the CDI box and measured the voltage to the coil and received 0 volts. Jumping the start relay only spinning the starter, but you also need voltage to other circuits for it to run. Already swapped the cdi unit and the coil. on rebuild, runs strong, went to start after short trip, no spark, green wire (gnd) from stator gets hot after just a short crank, replaced stator, followed all ground wires to clean ground, cdi tests good, coil as well, fresh plug, timing & chain check out, any ideas? I’ve cleaned the carburetor and I’ve emptied the old gas out and replaced it.the spark plug seems to be good. Stator Test. It will not start. I have a mdi 150 cyclone it runs with key on crank let go and shuts off. If you just tap the start button as its dying it energizes the ignition and it fires again but then continues to die. make sure your not using the kill switch of the cdi as ground, that’s for shutting the darn thing off. https://www.buggydepot.com/product/404/cdi-connection-kit-pigtail.html, https://www.buggydepot.com/tech-center/dazon-raider-classic-wiring-diagram/, https://www.buggydepot.com/tech-center/150cc-gy6-carburetor-cleaning-guide/. the other 2.
