- Start engine; verify ammeter reading remains stable.
- Check AC output across stator leads; compare to specifications.
- If rotor and stator good, check wiring, fuses, controller settings.
Separate Excitation Procedure diagnostic
⚠ Hazardous voltage. Operate the generator set only when all guards and electrical enclosures are in place.
Tools: DC ammeter, 10-amp fuse, 12-volt automotive battery
- Disconnect the black FN and FP leads from the alternator at the brush holder terminals.
- Connect a DC ammeter, 10-amp fuse, and a 12-volt automotive battery to the FP and FN brush leads.
- Note and record the ammeter reading.
- Start the engine and check that the ammeter reading remains stable.
- An increasing reading indicates a shorted rotor; a decreasing reading suggests a running open.
- Check for AC output across the stator leads and compare to Section 1 specifications.
- If rotor and stator are good, check the wiring, fuses, and controller settings and connections.
Test Low Oil Pressure (LOP) Switch diagnostic
Tools: Ohmmeter or continuity tester, Oil pressure gauge
- Press OFF to stop engine.
- Disconnect lead 13 from the switch.
- Use ohmmeter/continuity tester to verify switch is closed (grounded).
- Start engine and verify switch opens after a few seconds.
- If not operating, remove LOP switch, install oil pressure gauge.
- Start and run generator set.
- Verify oil pressure within specified range before replacing LOP switch.

Troubleshooting
6Fault codes
| Code | Meaning | Cause |
|---|---|---|
| BusDeadLive | The bus is measured to be dead when one of the generators is supposed to be supplying voltage to the bus (closed contactor). | Bus metering V9A and V9B connections to V9 of paralleling protection harness are connected incorrectly. |
| BusLiveDead | The bus is measured to be live when no generators are connected to it (both contactors open). | Bus metering V9A and V9B connections to V9 of paralleling protection harness are connected incorrectly. |
| CfgModelNum | The two generators that are intended to be paralleled have incompatible model numbers. | Incorrect configuration of one of the generators. Different generator types. The paralleled generator sets must be the same kW model. (i.e. two 14 kW or two 20 kWor 26 kW models). |
| CfgSysVolt | The system voltage of the two generators intended to be paralleled is not the same. | One of the two generators is incorrectly configured. Intermittent connections on RBUS network wiring. |
| ConCheckFail | Failure to Auto-Discover APM connections. | Wires 9A and 9B crossed between the generators. Wires 9A or 9B not connected. |
| ConNotDeterm | APM connection auto-discovery is not complete. This means that the generator does not know which contactor is connected to it. | Generators not yet started in RUN with other generator in OFF. See the APM instruction sheet for instructions to perform the auto-discovery procedure. |
