Default Coil Question...

Guys,

I was wondering if anyone knew whether or not the coil is specific to either cylinder? I would just try swapping the plug wires on my bike but it's in a million pieces right now.

Thanks,
Greg

The coils have one primary winding and two secondary windings, so every time the primary is electricaly activated, both secondary coils provide a spark. Many 6 cyl. car coils work the same way.

Not so unless you have an older Sporty. Current models (2000 up ?) use a single fire ignition. Looking at the coil from the left side of the bike, the closest coil connector gets connected to the front cylinder.

Thanks for the help guys... I just threw enough back together on my bike and cHarley is indeed correct.

After switching around the plug wires and cranking the bike over she did not start. I did manage to shoot a few 2-3 foot flames out of my short shots in the process

Time to rewire the coil plug to see if I can run the plug wires the way I want to.

FYI... rewiring the coil works if you want to change the plug wire layout on the bike. It was very simple, open up the plug, swap around two wires. Piece of cake. Fired right up!

OK, I found which wires to swap in the coil plug:

Just swap the blue+yellow stripe wire with the yellow+blue stripe - they should be right beside each other. (Just a FYI - The other two wires are yellow+green stripe and look very similar to the yellow+blue.)

You need to remove the pink bit of plastic at the end of the plug first, it was difficult but keep working at it carefully. Then just push the black plastic clip that holds each wire and swap them out.

I just installed some red SE spark plug wires from the Rocker and it looks pretty sweet.

I know this is an old thread but the info would be good to keep here I think...
