[SEL] Wico magneto

[Dave Ernst]

Mine is not an Eisemann, it's a Makelim.  What I did prior to the tester was 
usie an old base mount Bosch mag off a Caterpillar pony motor.  I cut the 
aluminum top off at the coil location, discarded the front cover, installed 
a good set of points and new condenser. Set the coil to be tested over the 
exposed magnets, connect the leads and use an insulated screwdriver to gauge 
the length of spark jump to the mag casing.  I spun it with a 3/8 hand drill 
chucked to the armature.  Worked fine for a long while. But, what I did find 
after getting the tester and using their values that a coil that looked good 
on the Bosch wasn't up to snuff according to the Makelim tester.  I found if 
the given value is exceeded, the coil has a hard time creating enough spark 
to fire the plugs.

Liked your idea also.
