TM9-2920-225-34 FRAME 3 CAUTION 1. 2. 3. Do not use a battery or test lamp to make a continuity test. Reverse battey connection will burn out diodes instantly . NOTE On ohmmeters that use one 1 1/2-volt dry cell, low resistance 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. Positive rectifier has a coating of epoxy for insulation. Check positive rectifier (1) for resistance using a multimeter. Touch positive test probe to checkpoint one (2) and negative test probe to each of three rectifiers (3, 4, and 5), ohmmeter must show low resistance when negative test probe is touched to each rectifier. Check negative rectifier (6) for resistance using a multimeter. Touch negative test probe to checkpoint two (7) and positive test probe to each of three rectifiers (8, 9, and 10). Ohmmeter must show low resistance when positive test probe is touched to each rectifier. Get new parts for those which do not show low resistance. END OF TASK TA103570 2-69
