Ultima 18-533 Coil Power Issue

I have my boardtrack ready to fire up and I had no power from the harness module to my coil when the switch is turned on. I have the 18-533 Ultima harness assembly.

I was able to get fire to the plugs by adding a jumper wire from a switched 12v supply to the coil power terminal. But that's not right and I doubt that my kill switch will work correctly with the jumper.

Here's a section of the wiring schematic that shows the power to the coil as a white with black stripe. Lower right corner of the picture. I have that wire run directly to the coil 12v power terminal. When I power up the bike, the white with black stripe wire is dead.

Anyone have this issue?

Here's the coil wired up.

Thanks in advance.

The wiring for the right side handlebars was not too clear and I used a push button in my BDL controls for the KILL button. It should have been a rocker switch. I found that if I held in on the button that I have 12v power to the coil, problem solved. I hid a small toggle switch under the tank as a second safety that's actually the KILL switch. I'll just leave it on and use the main switch to start/stop the motor. If necessary, I can easily reach the hidden switch while on the seat.

As for the single front cylinder firing only, I did a complete check on the coil and it ohm'd out correctly and both sides were identical in resistance.

I replaced the coil and I now have both cylinders firing niecely. Go figure a brand new 11 year old coil going bad on build startup.

Thanks, Dan
