Some of the kits come with instructions to run the kill switch between the white wire and a frame ground. Mine did, and that's the way I have mine wired. That configuration shorts the magneto instead of the CDI.
As I understand it, the white wire was
intended for use as a kill switch, so you're doing it the best way.
However, I understand some of the kits come with instructions to wire the kill switch into the CDI wires. From what I've read, that's the more dependable way to wire the kill switch.
Some kit instructions say a lot of things, but there's absolutely no reason why shorting the blue wire would be a more dependable way of killing the engine. Either the blue or white will work well from that perspective.
The blue winding is higher power and easier to damage by short-circuit.
Also, logic tells me that if it was acceptable to short the blue wire, there wouldn't be a white wire at all.
I've read a lot of posts that suggest putting the kill switch on the blue wire, but in series as I suggested, not shorting to ground.
Really, either way would work with the lights.
I'm still not convinced that it's a good idea to run lights off the white wire.
It
will rob some energy from the ignition system.
Rileyk, just saw your latest post - if you
must run lights, why can't you still connect the white wire to the kill switch?
Point me in the direction of the thread on 'norm's lights' and I'll check it out.
Thanks, fairracing31, I thought it should be OK.
