Pinpoint Test Notes

CAUTION: Do not make jumper connections except as directed. Improper connections may damage the voltage regulator or fuses.

NOTE
^ All voltage measurements are referenced to the negative (-) battery post unless otherwise specified.
^ All ignition switch in RUN measurements are made with the engine OFF unless directed to start engine.
^ When the battery has been disconnected and reconnected, volatile memory functions will be lost, affecting vehicle performance.

Use Rotunda 73 Digital Multimeter 105-R0051 or equivalent to perform pinpoint tests.
