01B
Status Indicator RAPs
01B 0V Distribution RAP
Use this RAP to identify 0V distribution faults.
Procedural Notes
NOTE: If a voltage is measured between ground and a return 0V line, then the continuity of
that 0V circuit must be checked.
NOTE: To isolate a 0V distribution fault, perform the following:
1.
Check the continuity of a harness while the harness is disconnected at both ends. This is
to ensure that other wiring does not cause false continuity readings.
2.
Check the continuity and perform a visual inspection of each connection sequentially,
back to its source.
3.
Check that any in-line connectors are installed correctly.
4.
Check that all connectors are mechanically good. Check crimping for suspect electrical
connections or any mechanical failure that could cause a failed or poor electrical contact,
GP 7
. Refer to
REP 1.2
for information concerning wiring harness repairs.
NOTE: The expression ‘return’ is used to identify the 0V line that completes the circuit for a
particular voltage.
Procedure
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14
. Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
Go to the 0V circuit that has the suspect problem:
•
01B +3.3V Return
.
•
01B +5V Return
.
•
01B +12V Return
.
•
01B +24V Return
.
01B +3.3V Return
Go to the appropriate component in the list that follows that has the suspect 0V supply. Check
the wiring
