If you have a remote starter switch, you can get to the wires on the solenoid.
Connect your aligator clips between the little one to the side and the big one.
You
may need a floor jack. Or pull all the plugs, ground the coil, and just do each
hole
in turn. Make sure you give it all the throttle during the check.
Alternatively, you could just see if the motor has sufficient power then, with
your
tach/dwell meter hooked up on the low range tach, pull each spark plug boot on a
running engine and see how much RPMs you lose. It should be measurable (~200
rpm)
and even.
