TM 9-2350-261-34 5.6.Use multimeter to check diode. Set meter toabove 200 mV scale. Place probes on eachend of diode. Switch probes. Multimeterreading will be infinity or resistance in eitherposition. One position must read infinity andthe other resistance and vice versa for diodeto operates properly.Use multimeter to check motor resistor. Placeprobes on resistor leads. Multimeter shouldread 0 ohms resistance. Replace resistor ifreading is infinity.INSTALL7. Install motor resistor (1) on bracket (2) withscrew (3) and nut (4).8. Secure motor resistor (1) leads to terminalsNo. 4 and No. 6 of terminal board (5).9. Install diode (6) in holder (7).10. Install guard (8) on heater (9). Secure withfour screws (10).FOLLOW-THROUGH STEPS 1. Install engine coolant heater in carrier(see your -20).END OF TASK14-59
