Test 2, Check For Spark During Crank

Using Neon Bulb Spark Tester (D89P-6666-A), check for spark at each right side spark plug wire while cranking. If spark is present and consistent (one spark per crank revolution) on all right side spark plug wires, go to next test. If spark is not present or is inconsistent, go to TEST 5.
