I have a problem with my bike , I hooked up a small 6v tailight to my bike . made sure that I have a good ground and then hooked my white wire to the light. the light will come on , but the motor will not start. I pull the bulb out and the motor starts. I have changed out magnetos to see if that was the problem and got the same results. is there something else I should look for? would changing out the cdi box help? I know that this system will work , because another rider has this set-up and works fine for him! when I pull the bulb out and test it on the bike , I touch the white wire to the bulb then touch the electrode of the bulb to ground and it lights up,but it also wants to kill the motor. (goes to ground) I also have a micargi cruiser with a 6v light set-up (headlight and taillight) and it works flawlessly and lights up well. the wire set-up is the same, light housings to ground and white wire to bulbs. am I missing something?
