CAUTION: W hen probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number

3548-1358-00.

• NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

• NOTE: When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to 3 decimal places, and
with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.
