Subject:Re: High resistance causing no spark?

Thank you everybody for your replies!! You don't know how much I
appreciate the help :)

I remeasured the wire and found it at about 12000 ohms... went to the
parts store, opened up a set of wires, and measured the same wire -
about 9000 ohms. So close enough, I figured (they have a restocking
fee, so didn't want to take them home to test). I tried Mark's trick
of attaching a spark wire with spark plug attached, and grounding that
to the block - no spark :(

Tested the low-tension lead that attaches to the coil - with the
ignition on, one multimeter lead attached to the LT lead and one
multimeter lead touching the block, it read ~11.5 volts. So, we figure
that power is getting to the coil, but no farther - bad coil? Is there
any way to check (I tried the resistance test between center and side,
and between both sides, and found it to be a tiny bit out higher than
spec).

Thanks again!!
Mike.
