A coil is just a transformer. It steps up voltage from what you
have(12V) to
what you want(up to 40000) The coil resistance doesn't mean
much, the spec is
for trouble shooting the coil. Although
the coil resistance is related to coil voltage, it is not a
direct
relationship. Thinner or longer coil windings give more
resistance. Primary
coil(less windings) induces a current in secondary coil(more
windings). The
ratio beween the number of times wire wraps around each
coil(windings)
is the ratio of volts in/ volts out. For example, 10 turns on
pri,10000 turns
on sec, or 1:1000,
will change 12 volts to 12000 volts. But it will also reduce
amperage by same
factor.
The whole idea is to make enough voltage to make a spark.
