Steve,
You can not properly test a coil with a common ohm meter except for
total failures like open, nearly open, shorts between windings, and
maybe direct shorts from terminals to ground. First off, unless you
have a pretty sophisticated ohm meter you really can not accurately
measure resistances below a few ohms. For most consumer and development
lab ohm meters measuring .9 ohm across a circuit that is supposed to be
.6 ohm would be within expectations. If you have a high end milli-ohm
meter then it would be suspicious but not necessarily indicative of a
bad coil.
