spark

Hi All, I need some help troubleshooting an electrical issue on a silver tag CT70. Here are the facts. Bike has likely not run in 40 years. I believe my wire harness and key switch are good. New bulbs installed everywhere and verified operating. Good battery installed. New coil from Dr ATV...

I have a 1971 CT70. The plug wire broke so I ordered replacement coil. I dropped the motor and changed it out. Now I'm getting no spark. I can feel a little zap from the plug when I touch it, but not enough to get a visible spark. Anyone ever run into this with after market coil and plug wire...

I bought a used motor to drop in my ST90 as mine is locked up. I installed the replacement motor. I installed a new battery. I made sure all connections were connected (that I can see, I am no expert on ST90) If I kick it, I get no spark... I get power, as the speedometer light works, neutral...

Going through the electrical system today, my step-dad rotated/twisted the coil wire out out of the coil (like you would for the spark plug boot) and found that it appears the wire isn't supposed to be removable. The wire needed replacement for sure, but there's nothing on the inside of the coil...
