[SEL] Magneto/Battery Ignition Question

Sun Mar 26 16:31:36 PST 2006

Yes, it will. Maybe some of those folks out here don't want to risk it, do
what you want, but there is the risk of demagnetizing a low tension mag.

If you wanny play Russian roulette with your mag, fine, but I won't suggest
it's ok for others to do it.

Use a single pole double-throw knife switch and you can do it safely.
There's a good clean safe way to do it.

Naw, won't hurt a thing.  Of course when the mag is open circuit you have to
have the battery/coil hooked up or the darn thing won't start at all.  I
know this because I've been asleep at the switch a time or two.
