I have a scoot that has been sitting for a year. I recently bought a new motor for her. When I hooked it all up as soon as I would start to attach the starter wire she would try to start. This will happen with the key in the off position and the kill switch engaged. Thought it may have been the starter. Replaced it with a known good starter same thing. Thought it was the CDI. Switched out with known good CDI same thing. Also would still do so even with CDI disconnected. Thought it was the alarm box. Removed the alarm, same thing. The battery is also a new lithium ion battery 7amp. When I disconnect the green ground I can put the starter wire on the solenoid, but as soon as the wire grounds it tries to start. I disconnected the solenoid from the harness, still will try to start. Lights work, horn works, blinkers work. Hopefully someone can help.

Also, I have looked at the wiring throughout the harness, all connections secure, no frays, or melting. I have a multimeter, but dont know what readings I should get and where to check. The battery reads 13.25. Every connection if i touch the ground on the solenoid to any connection i get 13.25. If I touch the ground solenoid and the casing on the starter i get the same. I have the engine grounded to the frame from the bottom of the engine casing bottom fan to engine screw -to the frame itself.

sounds like a starter solenoid is stuck .

Here is how the electric start works: Alleyoop 1. The thick positive red cable from the battery goes to a Terminal on the Solenoid and the other Terminal on the Solenoid goes to the Starter. 2. With Key on it sends voltage to the brake switch. 3. When you squeeze the Brake it sends voltage to the SOLENOID and to the BRAKE LIGHTS(it splits). 4. When you PUSH the START BUTTON it GROUNDS the SOLENOID to complete the circuit and it sends 12V from the battery to the starter. So with knowing that and if all is connected right it could be that the SOLENOID contact inside is stuck sending voltage to the starter all the time and when you go and ground it, it completes the circuit. Or the brake switch is stuck on the on position so check if your brake lights are on when you turn the key to on. You can test the YELLOW AND GREEN going to the Solenoid in the picture and see if it has voltage without squeezing the brake. Alleyoop  |

Had to fix a few more things. Brake light bulb was out, fixed it. Front brake light switch was stuck, wiggled the wire until it popped back out. Still wants to turn over with the key in the off position and kill switch engaged so, John, (you and Alley, have helped me out a bunch over the years(Scootdawg handle was Lukain) I will instead of buying a solenoid from a dealer in town will throw a bone your way. Wish at the moment I can do more...hehe but im sure later there will be. If I ran into any other issues that you supply parts for I will try to order them from you.
Side note: the old motor that I supped up ended up running great for about 6k miles. However, i was driving her 120 miles a day (60 miles each way) at 65-75mph( Was passing cars on the freeway doing the speed limit(65mph), Loved some of the looks I would get as I passed them). One day at work she wouldn't engage the starter and when trying to take her apart i found that the variator had fused to the crankshaft. I never opened the other-side but i believe the starter gear popped out of place. (Once I saw what happened to the cvt-side I didn't bother) I figure that the roller on the variator fused because I over torqued the nut. Lesson learned.

Well here is the thing If it still wants to turn over with the KEY in the off position there should not be any juice flowing to anything that means it is still sending juice to the Brake switchs and the Solenoid which it shouldn't. So it looks like some wiring has been done and wired wrong.
I would follow the GREEN and YELLOW wire on the SOLENOID and see what it is connected to. That green and yellow wire should go to the brake switchs where it should get its juice when the brakes are squeezed. The other wire on the solenoid should go to the START BUTTON as a ground.

To the solenoid I have the red battery on one side. The other side I have the black battery and a solid green for ground. All other connections match color to color. the lead from the solenoid matches color to color to the other connection for the brake lights and power switch. The choke wires match color to color. The cdi matches color to color. The stater matches color to color. This is an original wiring harness. If I don't put the starter red onto the solenoid red side All works. When I hit the start button I can hear the solenoid make a switch click. But soon as I touch the starter red to the solenoid it try to turn over.

God I am an idiot. OK, all that is working now. The next issue I may have is the "Hi performance ignition coil wire" doesn't fit snug on the plug. Will try to tape the cap tightly to the fan shroud to hold the wire on tight to see if it will fire. If it does then I will replace wire, if it doesn't I will still replace wire. Dam@! DAM@! DAM@! I...can believe I was doing this...

The coil wire where is it loose by the BOOT CAP that goes over the PLUG? If so they screw on just like a regular screw as a mater of fact it is like a wood screw SO TURN the BOOT CAP CLOCKWISE onto the wire till it is nice and snug.
Yes what you said before your last post you had the connections wrong, Red thick battery wire goes to One Terminal on the SOLENOID and the other Terminal on the Solenoid Goes to the Starter. The NEG POST on the battery goes to GROUND on the frame.

The plug on the boot cap side must be missing some sort of fitting on the inside. I understand how it is supposed to fit on there but it seems as though it is made for a bigger plug. there isn't anything small enough for the spark plug it snug into. I looked at my oem coil wire and it had a small fitting in there to grip the plug, this new one doesn't have it. I tried using the oem fitting(small hollow screw with a spring and contact) but it wouldn't fit.

Yea sometimes the brass fitting inside that grab the plug threads break off if it is taken off to many times. You can get a new boot cap at any auto part store they are on a couple of bucks. Just get the angle as yours and then screw on the new one onto the coil wire.
