Generator Isolating for Maintenance

Check the electrical wires daily for wires that areloose or frayed. Tighten all loose electrical wiresbefore the engine is operated. Repair all frayedelectrical wires before the engine is started.

Grounding Practices

The electrical systems for the generator, the engineand the control systems must be properly grounded.Proper grounding is necessary for optimumperformance and reliability. Improper grounding willresult in uncontrolled electrical circuit paths and inunreliable electrical circuit paths.

Uncontrolled electrical circuit paths can resultin damage to main bearings, to the surface ofcrankshaft journals, and to aluminum components.Uncontrolled electrical circuit paths can also causeelectrical activity that may degrade the performance

of the generator set's electronics.

The alternator and the starting motor must begrounded to the negative battery terminal.

A ground plate with a direct path to the negative battery terminal may be used as a common groundfor the components of one engine system.

For engines with an alternator that is grounded toan engine component, a ground strap must connectthat component to the negative battery terminal.Also, that component must be electrically isolatedfrom the engine.

The ground strap for the alternator must be of a sizethat is adequate for carrying the full charging currentof the alternator.
