Table 5-1 Troubleshooting Procedures
Poor or broken
Set multimeter to dc volts
Connect positive meter
lead to TB2-1 and negative meter lead to TB2-2.
Meter should indicate more than 1 vdc.
(1) If meter does not indicate more than 1 vdc
for both tests, turn power switch S3 to
(2) Set multimeter to ohms Connect leads to
TB2-1 and TB2-2, and then to TB2-2 and
TB2-3 Meter should indicate 100, 000
ohms or more for both tests.
(3) If the meter indicates less than 100, 000 ohms,
inspect wiring and P1 for shorts, broken
or loose connections, or bent pins.
Connect meter leads to the following points:
TB2-1 to P1-25;
TB2-3 to P1-13;
TB2-2 to outer enclosure;
TB2-2 to P1-3, 4, 16, 17;
TB2-2 to P1-23;
TB2-2 to battery negative lead;
TB2-2 to TB3-3.
Meter should indicate 0 ohms at each point.
If the multimeter reads more than 0 ohms at any of
the above points, inspect wiring for broken or loose
connections, inspect plugs for bent or broken pins
and inspect conduit for poor connections. Repair
