49 State

^ A spark plug with a broken side electrode is not sufficient to check for spark and may lead to incorrect results.

^ The AC voltage readings in the Pinpoint Test steps are all based upon readings taken with a "standard" Volt/Ohm Meter (Rotunda 007-0001 or Fluke 20 or 70 series). Do not use a "true" RMS type meter such as the Fluke 8060a because the AC voltage readings obtained may be significantly different, leading to incorrect answers to the questions asked in the Pinpoint Test steps.

^ When making measurements on a wiring harness, both a visual inspection and a continuity test should be performed. Inspect the connector pins for damage (corrosion, bent or spread pins, etc.) when directed to remove a connector.

^ When making voltage checks, a GROUND reading means any value within a range of 0 to 1 volt. Also B+ readings mean any value that falls within a range of 10 to 14 volts.

^ When making voltage checks and a reference to ground is made, use either the negative battery lead or cast iron on the engine. B+ means the positive battery cable at the battery.
