NOTE Note direction of arrow on diode so it can be installed later. 2. Remove diode (Figure 2, Item 4) from holder (Figure 2, Item 5). 3. Remove motor resistor (Figure 2, Item 8) leads from terminals No. 4 and No. 6 on terminal board (Figure 2, Item 7). 4. Remove nut (Figure 2, Item 6), screw (Figure 2, Item 9), and motor resistor (Figure 2, Item 8) from bracket (Figure 2, Item 10). Figure 2. Diode/Motor Resistor – Removal. END OF TASK TESTING 1. Use multimeter to check diode (Figure 3, Item 4). Set meter to above 200 ohms range. Place probes on each end of diode and note reading. Switch probes and note reading. One reading must indicate continuity and other reading must indicate high resistance, if they do not replace diode. Figure 3. Diode – Testing. TM 9-2350-277-40&P 0031 CHANGE 1 0031‐2
