ARMY TM 9-6115 464 34AIR FORCE TO 35C2-3-445-2NAVY NAVFAC P-8-624-34a. Testing Exciter Stator (On Equipment Test). Locate and disconnect exciter stator winding resistance usingohmmeter. On the 15 kW and 30 kW generator sets, leads F1 and F2 are located on the terminal board near the staticexciter/voltage regulator control box. Check across leads F1 and F2 for resistance. A normal resistance reading of 1 to 4ohms should be found. If the resistance of the exciter winding is not as specified, refer to the applicable section of the TMfor replacement/repair of the exciter stator winding.b. Equipment Test of Field Flash Circuit Assuming the exciter stator winding resistance is correct (within 1 to 4 ohms)Connect a DC voltmeter (0 to 30 volts) to the two wires that are disconnected from the exciter stator windings. NOTE :DO NOT reconnect the wires to leads F1 and F2 at this time.c. Remove Connector P37 from speed switch. Place a jumper between pins A and C on P37. Momentarily,approximately 10 to 15 seconds, place the START-STOP-RUN switch in the START position and observe the DCvoltmeter. If the voltmeter indicates approximately 24 volts, the probable cause of the field flash is the speed switch. If aDC voltmeter is not available, proceed to step d.d. Remove Connector P3 from the speed switch. Place a jumper between pins A and C of socket J3 on the specialrelay box for approximately 24 volts DC. If a DC voltage is not present, the problem may be the wiring between the speedswitch and the special relay box, the K5 relay, or current limiting resistor (R35) inside the special relay box (15kW and 30kW generator sets only). If a DC voltage is present, replace Connector P3 on socket J3 and proceed to the next step.e. Remove Connector P9 from the static exciter/voltage regulator control box. Momentarily, hold the START-STOP-RUN switch in the START position and check between pins C and D of P9 for approximately 24 volts DC. If a DC voltageis not present, the problem may be the wiring between the special relay box and the static exciter/voltage regulator controlbox. If a DC voltage is present, replace Connector P9 on-socket J9 and’ proceed to the next step.f. Remove Connector P13 from the static exciter/voltage regulator control box. Momentarily, hold the START-STOP-RUN switch in the START position and check between pins S and R of J13 on the control box for approximately 24volts DC. If a DC voltage is not present, the problem may be any one of the following items within the control box:(1) Broken wire within the control box.(2) Current limiting resistor R219 sets.(3) Current limiting resistor R17 sets.g. Reconnect the wires previously removed from the exciter field winding, F1 and F2.Section XIV. MAINTENANCE OF ELECTROMAGNETIC INTERFERENCE SUPPRESSION COMPONENTS3-96.
