If continuity, do next step.

Step 13.

Check for continuity between J5-21L and terminal 2 of MASTER SWITCH

1S2.

If no continuity, replace wire P34D20. Reconnect all

connectors, and perform operational check.

If continuity, test battery/charger transfer relay 3K3 and

wiring (malfunction 85, step 1).

FUEL METER READING INACCURATE.

indicator lights.

a. If LOW FUEL indicator lights, do step 2.

If LOW FUEL indicator does not light, see malfunction 6 or 7.

Disconnect battery and lower control panel (paragraph 4-24.a).

Step 2.

Disconnect wire from negative (-) terminal of FUEL meter 1M3 (see

FO-4). Tape wire terminal lug to prevent shorting.

Battery power may be present at terminals on back of control

panel when battery is connected. Do not touch any bare

terminals.

Step 3.

Connect battery. Set MASTER switch to ON. Measure dc voltage

between positive (+) terminal of FUEL meter 1M3 and ground. Set

MASTER SWITCH to OFF, and disconnect battery.

a. If voltage was between 4.6 vdc and 5.6 vdc (normal), go to

step 7.

If voltage was 0 vdc, reconnect wire to negative (-) terminal

of meter 1M3, and go to step 5.

If voltage was between 22 and 26 vdc, reconnect wire to nega-

tive (-) terminal of meter 1M3, and continue with next step.
