Organizational Troubleshooting (continued)
TEST OR INSPECTION
support cable and lower control panel onto access door.
c. If diode to be tested is on TB2 (10, 11, figure 4-20) or TB3
(4, 5), remove battery charger access panel.
The teat procedure is the same for any diode type 1N5061 or MR756. Diode
Remove terminal screw (1) and one lead of diode (3).
Using an analog multimeter (AN/PSM 4 or equivalent) on X1
scale, measure resistance from diode anode lead (9) (meter
positive lead) to diode cathode lead (11). If resistance is
greater than 25 ohms, replace diode.
Set meter to X10,000 scale and measure resistance from diode
cathode lead (11) (meter positive lead) to diode anode lead
(9). If resistance is less than 10K ohms, replace diode.
If diode is good, reconnect diode lead to terminal board.
95% ENABLE RELAY 3Kl MALFUNCTION.
If the 95% enable relay 3K1 is suspected of malfunction, teat relay and
associated wiring as follows:
Disconnect battery and lower control panel (paragraph
Open electrical trays access door.
Disconnect main harness connector P8 from electrical tray
Perform tests indicated in table 4-6 for relay in deactivated
