Check battery charger input and output cable connections for looseness or corrosion. Check all components for loose mounting, poor solder connections, broken wires, overheated resistors, or any other signs of damage.d.InspectStarterRelaysK1andK2. Starter relays K1 and K2 are located near the starter motors (see Figure 3-3). Inspect the relays for secure mounting. Inspect for signs of overheating or corrosione.InspectHIGHCoolantTemperatureSwitchWT2. Ensure that the coolant temperature switch (Figure 3-3) is clean, does not leak, and that the connector is undamaged and secure.f.InspectLOWCoolantLevelSwitchesS13andS14Ensure that the coolant level switches S13 and S14 (figure 3-3) are clean, do not leak, and that the connectors are undamaged and secure.g.InspectLubricantTemperatureSwitchOT2. Ensure that the lubricant temperature switch OT2 (Figure 3-3) Is clean, does not leak, and that the connector is undamaged and secure.h.InspectLOWOilPressureAlarmOP2andLOWLubricatingOilShutdownSwitchOP1Ensure that the oil pressure alarm switch OP2 and LOW lubricating oil shutdown switch OP1 (Figure 3-3), are clean, do not leak, and that the connectors are undamaged and securei.InspectSpeedSwitchSS1/SS2/SS3. Speed switch SS1/SS2/SS3 (Figure 3-3) is mounted on the engine next to the mechanical governor Ensure that the switch is clean and that the connectors are undamaged and secure.j.InspectAirBoxDisconnectOilPressureSwitchOP3. Ensure that the air box disconnect oil pressure switch OP3 (figure 3-3) is clean and that the connector Is undamaged and secure.k.InspectDCCircuitBreakersCB1andCB2(24VDCCONTROLPOWERCIRCUITBREAKERCB1andEMERGENCY LIGHTING CB CB2) The generator set contains two DC circuit breakers. Both are located on engine control panel C (2 and 17, Figure 2-1). Ensure that the 24 VDC CONTROL POWER CIRCUIT BREAKER CB1 and EMERGENCY LIGHTING CB CB2 are undamaged and that no discoloration is evident.I.InspectStarterMotorsB1andB2. Cables and Solenoid. The two starter motors B1 and B2 are mounted on the rightside of the engine (see Figure 1-5)(1)Inspect terminals on starter motor solenoids for corrosion.(2)If corrosion exists, disconnect battery ground cables Tag and disconnect battery cables to solenoids one at a time. Remove cushion clamps and clean terminals as required to produce bare metal surfaces(3)Check starter motors and solenoids for damage and secure mounting.(4)Check surfaces of starter motors for signs of overheating, discolored or blistered paint.(5)Connect battery cables to starter motor solenoids, remove tags and replace tiewraps. Reconnect battery groundcables.m. EmergencyLightsDS20throughDS23 The generator set contains four emergency lights one located in the controlroom and three mounted in the engine compartment.(1)Inspect Inspect emergency lights DS20 through DS23 for secure mounting Check for broken light bulb and secure wiring connections Check light bulb operation by setting the EMERGENCY LIGHTS circuit breaker CB2(17, Figure 2-1 ) on engine control cabinet C to ON AC power must be shut off in order for dc lights to function.(2)Service Service as follows.(a)Remove lamp by pulling it out of rubber gasket.(b)Label and disconnect wires.(c)Connect wires to new lamp.(d)Install new lamp In rubber gasket.3-29
