Does anybody have a electrical wiring diagram for the 150 gy6. Mt scoot is not running and I need to figure out why. I have looked at about 3 wiring diagrams and they r not the correct ones. It did start and run before but now it doesn't. I have no spark. I already checked my coil and it was bad. Replaces it with a loner coil and had spark but my scoot still would not run. I don't know how to check my cdi. Which wire is suppose to be hot on my cdi??? If anyone could help it would be much appreciated. If it helps my scoot is a 2007 schwinn sport lx150cc.

Hey odie2ooo have you tried Jrryan, Jackthefuzz,or gy6rocket's wiring diagrams? I only ask because you said you looked at a few. These diagrams have pretty much all possible circuits which can be found on a majority of scooters.
As for the CDI, the Red on the 2 wire plug comes from the red on the stator. And the Red on the 3 wire plug should go to the pick-up for stator. (ez reference: gy6rocket's upgrade diagram)

The wiring diagrams I looked at I found on the web. I searched here on scootdawg but couldn't find anything.On my cdi I have 2 green wires and brown/yellow and a blue/yellow on the 4 pin connector and on the 2 pin connector I have a red/black wire and a black/white wire. Is there a way to test the cdi? If so how? Or is it just a piece you can't test and have to replace.

Well 1st here is Jrryan's diagram, he did absolutely brilliant work. I was mucking about with it with a few graphic and imaging programs soooo if any circuits are missing JRR has the original.
Now for GY6Rocket's. I remember being like the 100th person to PM him for electric help and he donated his time to put this together for a thread I started.
You should be able to identify circuits even if you have different secondary colors. But the basics should still hold true even on your scoot: RED= + , GREEN = Ground and BLACK = negative or return flow or complete circuit (I'm not sure, I got C's in those classes ) As for the CDI, I'm sorry but I have no idea how to trouble shoot a CDI. I's of the school that the best test for a component is to replace it b/c if the unit is defective I have no intention to try fixing it. Hope this helps. Tiger

Thanks for your help tiger. I think these diagrams will help me greatly.I also believe that is the best way to test things is by replacing them but that can get pricey if you replace 3 or 4 things that didn't need replacing. Thanks again for your help tiger,it is much appreciated.

since my coil messed up I bought a bando coil for my gy6 also because my cdi might be bad I also bought a high performance/racing cdi. Has anyone had any experience with these parts?

hi guys. first off, wanted to say thanks for this great thread. lots of great info. i have a question regarding the gy6 wiring diagrams 2btiger posted. i was wondering if it is totally necessary to have the red wire from the regulator directly connected to the + terminal on the batter? or if it can go to a switched +? the reason why i ask is because when i have a volt meter on the negative terminal (with the engine off and key in off) i am getting a drain of about 1 volt. as soon as i reconnect the red wire to a switched + the drain goes away. but returns when i reconnect to the + terminal. any input would be amazing. im doing a ruckus/gy6 swap and the electrical is kicking my butt! and i think i fried my 11 pole stator......

Well I checked my fuse and it is good. My brake light and turn signals work but I am not getting any power to my cdi. With my ignition switch turned on and my kill switch in the on position there should be one wire that has power. Does anybody have any idea's? I'm stuck

When the kill switch is in the "on" position it overrides everything and grounds out the ignition part of the CDI. The engine will not run with the kill switch turned on.

So there should not be a wire that has power to the cdi? What else should I check

The CDI gets its power from the stator. Usually a black/red wire. This occurs only when the engine is being cranked with the starter or the kick starter. There is no voltage present when the ignition is just turned on. I believe your first post said you have spark after trying the loner coil. If so, then the CDI is working.

Do you have any clue what else I should check?

why would I do that stradarx150te. The electronics all came off my original motor. If you have a legitimate reason then please explain but if not then please keep derogatory comments to yourself.

Odie "IF" the wires are like the one on the Bali diagram that is posted above and you have 4 wires to the engine on/off switch then this switch is a two-way switch as in a normally open and normally closed switch at the same time. If the switch is in the "run" position then the circuit that kills the engine in the engine off position is open and the other side of the switch is closed which then sends the ground side of the relay through the start button when you engage it. On this scooter there are two dark/green wires, one green/white wire and one black/white wire.
A test to see if the engine on/off switch is good or bad will be this;
Unplug all 4 wires and connect one of the dark/green wires and the green/white together, then leave the other dark/green and black/white wires apart, don't let them touch anything. Then hit your start button and of course you must have the brake handle engaged also as this completes the 12 volt+ side of the starter relay.
If you suspect you have a bad start switch then just unplug it and touch the two wires together after you have done the above and again press the brake handle.
All this again depends if your scooter is wired as the Bali. JRR

I'm sorry guys I made a mistake. The loner coil DID NOT spark.My buddy made the loner coil spark to make sure it was good. he could not make my coil spark so we knew it was bad. I'm guessing my cdi is bad but not sure, I already ordered another one. my wiring looks like gy6 rockets diagram. If the new cdi and coil doesn't fix it then I will try and wire around my kill switch and see if that works.
