Installed new valves (steel). Motors back on, everything is hooked up great but it looks like there is some kind of obscure issue going on with some unexpected connection somewhere on this thing. I have checked and rechecked and checked again.
The question I have specifically about how I am not getting any power to the wires on the solenoid when I turn ignition on, pull break in, and press start button. I get all lights on (main front light, breaks, signals... etc) when I turn the ignition on. I also measure ignition power to the CDI when ignition on... etc.
I only have about 100miles on this thing. I only changed out the valves because the exhaust valve got tight and wouldn't let it start and I would have to adjust it often given the history of cheap valves on these chinese gy6 knockoffs

Does the brake light come on with the lever pulled in while the key is in the run position ? Its common for a brake ligt switch to go out . Try the other lever andsee if it starts as well as make sure the killswitch is in run position

If the brakelight comes on, you should have +12 on the input wire of the start button when the brakelight is on. ( it might go through a kickstand switch before going to the start button). Once you have that follow the output wire from the start button to the start relay. ( it may go though a kickstand switch on the way as an alternative place for the switch. ) On most chinese scooters the engine kill switch has nothing to do with the starter circuit. ( other than the brain short circuit as to why won't it start now?  it cranks over, it aught to start...) |

You may have forgotten to plug in the solenoid into the harness.

Did you put the ground wires back on the head

I have the grounds on and double checked
There is no safety switch on either kick stand
Yeah the kill works at the CDI although i am still trying to fully understand how the kill works with the DC CDI. I guess the switch essentially ungrounds the power line to the CDI from what I can tell. It's different than how it works for AC i've read.
I haven't gotten this thing to turn. just run starter motor

How is this possible?
If the solenoid isn't getting power, how is the starter motor running?
I have a DC scooter probably exactly like what you have.
If you want me to look or check anything on mine, I will be happy to.
So is your starter turning or not?

The reason I can get my starter motor to turn is because I jumped the starter strait off the battery to test if I had a working starter motor. The starter relay is supposed to be connecting the battery and starter when I press the button. I have the BMS v9 evo scooter. Is that what you have?

Do the brakelights come on when you squeeze the brake, try both brakes. That is what sends the juice to the Solenoid.
That is why I asked if you plugged the solenoid plug into the harness.

Yes the brakes lights have always come on and I have plugged and unplugged the solenoid from the harness many times

Going into the solenoid are some small wires, the GREEN AND YELLOW is the power wire. Lets actually check if voltage is getting to the SOLENOID when you turn the key on and squeeze the brakes. Get a 12v Light Tester they are very cheap few bucks. Ground the wire and probe that wire if it lights up with the key on and squeezing the brake it is getting power. If that is the case then it is one of TWO THINGS, the Start Button is NOT COMPLETING the circuit by grounding the Solenoid or the SOLENOID IS BAD. If no juice is reaching the SOLENOID then you have to trace back the wireing to the Brakes. Now the brakes split the juice one goes to the brakelights and the other to the Solenoid. Alleyoop Light Tester is a life saver you can make tests quick and easy.  |

I'd already tested the solenoid wire with both my light tester and my multimeter when I posted this inquiry...
At this point it looks like this is not any kind of typically diagnosed problem. There must just be some random loose wire somewhere that people would never expect. I guess I'll just have to tear everything down to see every single connection and rewire it myself if needed. I was hoping to avoid that...

Ok I just jumped the solenoid again by putting the main battery wire directly on the starter wire briefly with the ignition on. My headlight stopped as usual when starter turned but engine did not get going. The starter just turned. A worrying thing that happened was that a ground wire that I think is the ground wire to the stator got very hot where it clicks into the harness and melted the protective clear plastic surround over the connection! what does that mean?
