CHAPTER 2: VEHICLE MAINTENANCE INSTRUCTIONS TM 9-2350-256-20 2-19 ELECTRICAL TROUBLESHOOTING-Continued ENGINE GENERATOR (SINGLE VOLTAGE SYSTEM)-Continued WARNING Remove all jewelry such as rings, dog tags, bracelets, etc. If jewelry contacts a metal surface a direct short may result in instant heating of tools, damage to equipment, and injury or death to personnel. D Reconnect APU and engine generator relays to voltage regulator wiring harness to engine regulator. Disconnect wire 2 of APU and engine generator relays to voltage regulator wiring harness from engine generator relay. Place red lead of multimeter on terminal of engine generator relay and black lead to ground. Turn MASTER switch on, start engine, open generator cutout switch and check for voltage. Turn engine and MASTER switch OFF, and close generator cutout switch. If voltage is present, go to step F. If voltage is not present, go to step E. E Reconnect wire 2 of APU and engine generator relays to voltage regulator wiring harness to engine generator relay. Disconnect wire 62/2 of APU and engine generator relays to voltage regulator wiring harness from APU generator relay. Place red lead of multimeter on wire 62/2 and black lead to ground. Turn MASTER and APU generator switches on, and check for voltage. Turn APU generator and MASTER switches OFF. If voltage is not present, repair/replace wire 62/2 of APU and engine generator relays to voltage regulator wiring harness. If voltage is present, replace master relay (see paragraph 6-2). F Reconnect wire 2 of engine disconnect to engine generator relay lead to engine generator relay. Remove engine deck (see paragraph 9-51). Disconnect generator power lead assembly from engine disconnect. Place red lead of multimeter in socket A of wire 2 and black lead to ground. Turn MASTER switch on, start engine, open generator cutout switch and check for voltage. Turn engine and MASTER switch OFF, and close generator cutout switch. If voltage is present, repair/replace wire 2 of engine disconnect to engine generator relay lead (see paragraph 6-62). If voltage is not present, go to step G. 2-132
