FIGURE 4-17. DIODE IDENTIFICATION
(4)
Tag and remove diode from circuit. Refer to Schematic FO-1.
(5)
Connect positive lead of multimeter to cathode side and negative lead to anode side of diode (9,
Figure 4-16). Refer to Figure 4-17. Multimeter should indicate open loop for diode.
(6)
Reverse multimeter leads so positive lead is connected to anode and negative lead is connected to
cathode side of diode. Multimeter should indicate continuity for diode.
(7)
If any indications are other than above, replace diode.
(8)
Install DCS control box top panel, paragraph 4.7.2.
