Headlight not working By jlohe2013 (Read 1,100 times)

I have a 2015 roketa Jamaica 150cc. I recently replaced the engine in it and ever since the headlight doesn’t work. Well is does work but only if I turn on the blinker and hold in the brake light when riding and the headlight blinks along with the blinker. I have no taillight either. Brake light works, blinkers work. The horn doesn’t always work either. I have pulled my bike apart since to check every connection and all is good. Not sure what the problem is

Check all the grounds around the handlebars and all of them in general,,,I've had very similar symptoms on other vehicles that lights wouldn't work till something else was turned on especially the turn signals,,,took me forever to figure it out

[lostforawhile]

did you put all the ground leads back on? is it the same stator wiring?

I can help with this, BUT YOU NEED TO ANSWER ALL OF MY QUESTIONS.

Are you willing to help me help you?

So sorry for the delay in responding. Didn’t know you had responded. All connections are the same and everything is connected properly. I’ve checked it over so many times. Can’t figure out problem.

Could it be the cdi I’ve been told that could be the problem

[jlohe2013]

I planned on changing the cdi. That’s the only thing it could be. Wish me luck

the CDI has nothing to do with the headlight, this is a classic ground issue, you have a ground wire broken right in front of a pin or something. you dont need to look at the wires, you need to test. you could even have a wire with a break in it. can someone post a wiring diagram for this bike here,so I can look at it? you need to look at a diagram then you can tell how current is traveling backwards through the other lights and where the biggest probability of a break is 

[lostforawhile]

if you have a regular single phase stator, you will have five wires, yellow,white, blue-white, red-white, and green, the yellow and white go to your regulator/rectifier and are AC for the lights and battery charging, these should go into the regulator, the regulator should have two outputs, one for your lights, one for the battery, and a ground, this ground is very important, the light output wire usually runs your taillight as well as the headlight, it goes to the high low beam switch, where two wires go to the headlight, the headlight socket also has a ground, check this very carefully. These grounds corrode and fail, somewhere in that front harness is a ground wire, or ground wires,heading back to the frame, check these very carefully.

what else does not work besides the headlights?
