TM 9-2920-225-34 FRAME 4 1. 2. 3. Check rectifier (1) using multimeter as follows. NOTE On ohmmeters that use one 1 1/2-volt dry cell, low resist- ance readings will be approximately 20 to 30 ohms. On ohmmeters that use a 3–volt dry cell, low resistance readings will be approximately 10 to 15 ohms. Touch positive test probe of multimeter to screw hole (2). Multimeter must show low resistance when negative test probe is touched to rectifier terminals (3, 4, and 5). Get a new rectifier (1) if it does not show correct reading. Touch negative test probe of multimeter to screw hole (2). Multimeter must show infinite resistance when positive test probe is touched to rectifier terminals (3, 4, and 5). Get a new rectifier (1) if it does not show correct reading. END OF TASK TA103511 2-13
