- Measure DC voltage between lead 31A (+) and ground (- ) with sender removed from coolant for at least 5-15 seconds; voltmeter indicates a drop to approximately 7 VDC.
3-Wire Low Water Level Sender Test diagnostic
⚠ Hot engine and exhaust system can cause severe injury or death. Do not work on the generator set until it cools.
⚠ Hazardous voltage. Moving parts. Will cause severe injury or death.
Tools: Ohmmeter
- Measure resistance between lead 31 and ground with sender submerged in coolant; ohmmeter indicates a high resistance reading.
- Measure resistance between lead 31 and ground with sender removed from coolant for at least 5-15 seconds; ohmmeter indicates a low resistance reading.
Battery Equalizer Troubleshooting diagnostic
⚠ To prevent reverse polarity damage to the battery equalizer, remove the ground (GND) connection first and attach the ground connection last when disconnecting the battery equalizer.
Tools: 12-volt test light with alligator clips, Voltmeter with 0.01 volt resolution, Battery load tester
- Remove the ground (GND) connections from the battery equalizer; do not allow contact with other connections.
- Verify a differential of 12 volts between the +12 volt and +24 volt terminals using a 12-volt test light; the light will illuminate on a functional unit. Remove the test light.
- Connect the test light between the +12 volt and GND terminals; the light will illuminate on a functional unit.
- With the test light connected, measure and record the voltage between the +12 volt and +24 volt terminals.
- With the test light connected, measure and record the voltage between the +12 volt and GND terminals.
- Remove the test light.
- Compare the values from steps 4 and 5; the difference should be - 0.5 and +0.13 volts on a functional unit.
Oil Pressure Sender Testing diagnostic
Tools: Ohmmeter, Mechanical oil pressure gauge
- Disconnect the oil pressure sender lead 7C.
- Check the sender resistance with an ohmmeter.
- Compare resistance values when the generator set is shut down and when running at operating temperature to Section 1, Specifications.
- Use a mechanical oil pressure gauge to further verify correct readings.
Overcrank Test (Typical) diagnostic
- On gas-fueled sets, disconnect the coil wire at the distributor cap and ground it or disconnect the ignition system.
- On diesel-fueled sets, unplug the fuel injector harness from ECM or disconnect wire no. 70 from the injector pump solenoid.
- Place unit in RUN mode; observe 15-second on-off cranking cycles and maximum 75-second elapsed time to overcrank shutdown.
- Observe controller fault lamp and display for an overcrank shutdown.
- Place unit in OFF/RESET mode.
- Reconnect the ignition coil wire/ignition system, or reconnect the fuel injector harness/wire no. 70.
Speed Sensor Test with Generator Set Running diagnostic
⚠ Keep leads connected to the speed sensor terminals during the test; do not disconnect the leads.
Tools: DC voltmeter
- Connect a DC voltmeter between positive (+) lead (wire 24) at the speed sensor and ground (wire 2) with master switch OFF/RESET; read approximately 8- 12 volts DC.
- Place master switch in RUN to start the generator set.
- Connect DC voltmeter negative probe to 0 terminal (wire 16 white) and positive probe to positive (+) terminal (wire 24 red); read approximately 7- 12 volts DC.
- Place master switch in OFF/RESET to stop the generator set.
- If sensor emits a signal, check continuity of speed sensor leads (wires 2, 16, 24) between controller P1 connector and sensor terminals.
Speed Sensor Test with Separate 12 VDC Source diagnostic
Tools: DC voltmeter, 12-volt battery or DC power supply, Flat piece of iron or steel
- Place master switch in OFF/RESET position.
- Disconnect the speed sensor leads.
- Connect speed sensor, DC voltmeter, and DC voltage source as shown.
- Touch sensing surface with a flat piece of iron or steel at least 4.1 cm (1/4 cu. in.) in size.
- DC voltmeter reading should equal the source voltage, approximately 12 VDC.
- Remove the iron or steel piece and observe a voltmeter reading of 0 VDC.
- If the sensor passes, it is functional; replace if it fails.
- Connect the speed sensor leads and adjust the air gap.
