Robin, you can jumper from a known 12 volt positive power source to the
positive wire on the ignition coil, and immediately crank the engine. You
should have spark at the plug leads. If no spark, then it is points,
condenser, or coil. Be sure to remove the positive lead from the control
board to the coil for this test.
