i'll start from the first problem i can think of on this scoot, my brother was riding it, and as he says it missed a couple times then died when he stopped and wouldn't start back, when he brought the scoot home i tried to start it and it fired right up, he didn't want it so i bought it from him for $50 then put a 82cc big bore kit in it, performance cdi 7g roller weights and an air filter on it. i go to fire it up to test the new engine...i have no electricity..i stripped the body off of it, and found a blown fuse, so i get a new one, still no electricity, i took a pair of rubber handled pliers to the bolts on the solenoid and it cranks right over but won't start, i check all of the wires and find nothing wrong with them...took out the spark plug and put it in the boot and held to the frame, its not getting any spark, i could rig up a hidden switch to start the bike so the electricity is the least of my worries, i just need to get spark to the plug. i hope one of you could help me, it would be much appreciated. thanks.

Is the kill switch engaged? Did you reverse the stator wires or the coil wires? Does the starter switch work at all or do you have to jump the solenoid?

kill switch is not engaged, i tried reversing the coil wires just to see if it would work and still nothing, i have to jump the solenoid with a pair of pliers or a screw driver before it will turn over, seems as if theres no electricity at all.

Well if it's turning the starter there is SOME power. How about the stator wires? Oh and on the coil one male connector should be black and one green. What colors do you have going where. When you pull the brake and the key is on does the brake light illuminate

i mean theres no power anywhere else...what can i do with the stator wires? its got the stock plug on it, all i did was plugged it back in when i put the engine back in. the coil wires : black/yellow goes to the cdi, the green one goes into the wiring harness, which has been cut every which way, but everythings connected as it should be. what SHOULD the coil be wired to? and the back brake won't come on because i took the body off of it, it didn't illuminate before either, if my memory serves me right.

I had something like this and it was a bad stator and magneto that went bad. Got a new one and no luck because it was a faulty one. The stator work but not the magneto. So I switch the magneto from one that worked to the new stator and wallah. Fired right up and all lights were nice and bright. good luck.

Before you start buying parts get a VOLT METER you can pick one up for under $10.00 and then you can check which one is the culprit. It could be your CDI, the Pick Up Coil the Stator or the Coil. It could even be just the BOOT that goes onto your plug, Now this is for SPARK and some lights.
Did you try both squeezing the other brake to see if maybe one brake switch is bad and one is good. Did you connect the red wire going to the key switch?

im actually flat broke at the moment, is there any makeshift volt meter i could use? maybe a flashlight bulb or something? i've tried a cdi, and the whole spark plug wire from a running scooter and it still didn't give me any spark. right now i've got the body off of the scooter (tail light was connected to it) and the scooter has been wrecked before and doesn't have a headlight/speedometer and only has back brakes. i plan on getting all of those fixed as soon as i get it running, (have a spare scooter headlight i can clamp on the handlebars) and ill have to buy another brake setup. however the keyswitch isn't stock. is there any kind of gy6 wiring harness graph around? so i can know what wires go where. because theres quite a few wires that have been cut and had other wires added on to the existing one. and i want to remove all of those so i can have just the stock gy6 wiring harness. sorry my post is so long, and thank you wile for your very helpful information

Im thinking your ignition isn't turning everything on. Does it do anything at all when you turn the key? And earlier I was wanting to be sure you had all the connections correct.

You may need a new ignition. I don't recall how to "hotwire" a scoot. I have done it once for someone who couldn't afford an ignition. I do remember sticking a 'u' shaped wire into the back of the ignition plug, thus arking one connection to the other. All he had to do was engage the kill switch to shut it off

We're assuming you have a fully charged battery if when you turn the key nothing happens. My gy6 has two fuses, one by the battery and one in the front by the rectifier. If one of those is blown you will not get anything out of your ignition key.

byseacall, can you show me a picture of the front fuse? my battery fuse isn't blown but i don't recall seeing the other one. scoot tech, the ignition is only 4 months old, if that. but if you remember how to hotwire it, please let me know, as i am too flat broke ): thank you all for all your help

Are you sure you aren't getting a spark? It is not usually a strong one anyway.
Either of these can cause "NO SPARK" Bad connections, Check at stator barrel connectors - CDI - Coil - Plug Wire.
Make sure the CDI is grounded (green wire) and the engine is grounded to the frame.
It can be a faulty ignition switch, faulty kill switch, faulty coil or plug wire & cap, faulty CDI, faulty stator, shorted black/white kill wire, or bad spark plug.
The black/red wire & the blue/white wire from the stator are the two wires that go to the CDI to make a spark. From the CDI the black/yellow wire (triggered voltage) goes to the coil. The green wire is ground & the black/white is the kill wire. Try cutting the black/white wire (leave it long enough to reconnect) to see if you get a spark, if you do get a spark the black/white wire is grounded and you won't get a spark with it connected. Check the kickstand for a safety switch & unplug it to see if you get a spark. If all the wires are connected & the black/white wire isn't grounded then you could need a coil or a CDI or a stator.

Also as Wile recommended you need a volt meter. If there are Harbor Freights in your area you can get one for like 4 bucks. It's worth it because you can test continuity in a wire to see if there is a break in it.

The fuse in the front of mine looks just like the one by the battery. I did have to take the front plastics off to find out that there was one there, but once I knew where it was it was kind of easy to get to from under the front fenders.

Scoot Tech
Black wire & Red wire are connected when the ignition switch is on and the black/white wire and green wire are disconnected. When the switch is off black/white wire & green wire are connected & red wire & black wire are disconnected

thank you all so much, i've cut the black/white wire, still the same thing, and since the cdi is brand new (plus i tried the old one too) and i've tried different coils/boots and the spark plug is brand new, i've narrowed it down to the stator (since the stator generates electricity and my scoot has none) that still doesn't explain why my starter button doesn't work though.....& byseacall i've looked and looked again, i have no fuse (or connecters) on mine, theres only the main fuse. by the battery. as we speak im reconnecting the kill wire, wish me luck on getting a new stator lol. thank you all very very much!

Maybe the wire Barnes is unplugged in the front end somewhere, trace all the wires and unplug and plug in all of the clip connecters, that is a typical issue with computers and other electronics.
