MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
Step 5.
Use voltmeter to check voltage at P1-36(+) and P1-18(-).
If voltage is 5 (±1) Vdc,
replace circuit card (paragraph
4-2j).
If voltage is less than 1 Vdc, check wiring from J2-D to
P1-36 and from J2-M to P1-18.
Repair or replace as
necessary.
14.
OVERLOAD MALFUNCTION LIGHT COMES ON - CURRENT LOAD NORMAL.
Step 1.
Connect GECM to test fixture in accordance with paragraph 4-2a.
If OVER LOAD light comes on, go to Step 3.
If OVER LOAD light does not come on, increase power supply
4 output voltage to 58(±1) millivolt dc.
If OVER LOAD
light comes on, go to Malfunction 17.
Step 2.
Use voltmeter and measure voltage at P1-48 and P1-18.
If voltage reads same as power supply 1 (28 Vdc), go to
Step 3.
If voltage is less than 28 Vdc, check wiring from J2-G to
P1-48 and from J2-M to P1-18.
Repair or replace as
necessary.
Step 3.
Use voltmeter and measure voltage at P1-24(+) and P1-18(-).
If voltage is less than 1 Vdc, check wiring from J2-C to
P1-24 and from J2-M to P1-18.
Repair or replace as
necessary.
If wiring checks good,
replace circuit card (paragraph
4-2j).
15. NO BATTERY CHARGING INDICATED.
Step 1.
Connect GECM to test fixture in accordance with paragraph
4-2a.Turn all power supplies off. Use an ohmmeter and check
the following:
