Test current boost transformer as follows: (1) Use an ohmmeter to test for 0.19 ohms between A1 and A2, B1 and B2, C1 and C2. (2) Apply 7 Vac 60 Hz to sec- ondary winding. Exciter current should be 75 milliamperes maximum. (3) Replace the transformer if test steps (1) or (2) above failed. b. Test instrumentation trans- former as follows: (1) Use an ohmmeter to test for 0.11 ohms between terminals A1 and A3, B1 and B2, C1 and C2. (2) Apply 10 Vac 60 Hz to sec- ondary winding. Exciter current should be 50 milliamperes maximum. (3) Replace transformer if test steps b. (1) or (2) failed. c. Test cross-current compensation transformer as follows: (1) Use an ohmmeter to test for 0.3 ohms between ter- minals A1 and A2. (2) Apply 10 Vac 60 Hz to secondary winding. Exci- ter current should be 50 milliamperes maximum. 5-39
