remove the distributor cap and clamp a test light to ground. hold the point of the test light about 1/2" from the coil output electrode. have someone crank the engine and look to see if sparks jump across to the point on the testlight. if they do the coil is ok. if they dont clamp the testligt to the + terminal of the coil and put the point on the - side. again, have somone crank the engine, if the light flashes the signal is good. replace the coil.
