4) Normal Operation

The system specifications, which are listed in Section 1-1, provide useful information when
troubleshooting abnormal operation. In particular, the Protective System Specifications and the Normal
Operating Characteristics provide information about how the generator set should be operating.

5) Check Connections and Leads

ALWAYS make a check of connections and leads to a component suspected of being faulty. With the
exception of a few instances, we will assume that connections and wiring have always been checked first
and that power has not been lost as a result of defective wiring or connections.

6) Engine Troubleshooting

When troubleshooting the engine, remember that the ability of the engine to start and run properly
depends upon the following:
•
An adequate supply of 12 VDC power reaching a good starter and starter button
•
An adequate supply of air, compressed to a sufficiently high pressure
•
The injection of the correct amount of clean fuel at the proper time
