tests results below, unsure what they mean
I purchased a brand new battery.
Connect a spark gap tester to the high tension lead coming from the ignition coil and set it to about 1/2". If it fires when you crank the engine over, there is a problem in the distributor cap, rotor button or spark plug wires.
I assume you want the spark plug tester at the bottom of the coil going to the distributor.
That test resulted in no spark. GOOD or BAD?
Check voltage on the blue wire at cranking. It needs to be at least 9½ volts. if not, the problem is likely in the harness, key switch, or battery.
Tested good, brand new battery
Connect a " DC voltmeter to the white/black wire, while it's connected to the distributor, and rotate the engine. There should be some change in the meter reading. If it's high, and fails to move up and down, there is a problem inside the distributor.
12 volt reading, did not go up or down. Nest Step?
If the reading is low, disconnect the white/black wire from the distributor and with the key switch turned on, strike the white/black wire against an engine ground. The unit should fire each time. If it does, then the CD module is usually good and the points need checking. Reading was high, but checked CD module just in case. Did you want a spark when against a engine ground or distributor turning?
check voltage on the gray wire going to the coil, with DVA meter, it should be 200 volts at cranking. No gray wire going to coil(blue and shite), gray wire going to aternattor/stator. Are you referring to different test? What does DVA meter stand for?
