5. Isolate both ends of the circuit
using the following methods as
required.
•
Disconnect the appropriate
connector at the micro-
processor.
•
Disconnect the device
connector at the device.
•
Disconnect the appropriate
connector at the interface
board.
•
Remove the wire from the
device terminal.
Harness
connections
are
identified in the Service
Procedures appropriate to the
device in question. They may
also be determined by consulting
the wiring diagrams.
CAUTION: Failure to isolate
both ends may cause
misleading results.
6. Using jumpers as required,
connect each end of the circuit to
a high quality multimeter.
The meter must show a very low
resistance (less than 1.0 ohm),
indicating circuit continuity. If not,
the circuit is open or has
excessive resistance.
Troubleshoot the circuit to
determine the cause using the
wiring diagrams.
Be certain the ohmmeter battery
is good and the meter zeros with
the leads held together to prevent
misleading results.
7. After determining that the circuit
passes a continuity test, remove
one lead and connect it to
chassis ground to check for a
short to ground.
The meter should indicate an
open circuit. If not, the circuit is
shorted to ground. Trouble-shoot
the circuit to determine the cause
using the wiring diagrams.
