Check under distributor cap for cracks, moisture or a missing center button.
#1 - Connect your voltmeter neg. lead to the engine ground and pos. lead to the white/red wire terminal at the dist. It should read 12 volts.
You want to tap the green/white wire end that comes from the distributor to ground with the key on to check for spark. Make sure you have a good ground on your spark tester.
You would only disconnect the red/white wire if you had no voltage.
Step #4 is done if you have no voltage in step#2
#3 - If there is no spark, substitute a new coil and repeat test #2. Now if you get spark, install a new coil. NO SPARK, replace ign. amp.
