Electrical System
Check the electrical wires daily for wires that are
loose or frayed. Tighten all loose electrical wires
before the engine is started. Repair all frayed
electrical wires before the engine is started. See
the Operation and Maintenance Manual for specific
starting instructions.
Grounding Practices
Correct grounding for the engine electrical system
is necessary for optimum engine performance
and reliability. Incorrect grounding will result in
uncontrolled electrical circuit paths and in unreliable
electrical circuit paths.
Uncontrolled electrical circuit paths can result in
damage to main bearings, to crankshaft bearing
journal surfaces, and to aluminum components.
Engines that are installed without engine-to-frame
ground straps can be damaged by electrical
discharge.
To ensure that the engine and the engine electrical
systems function correctly, an engine-to-frame
ground strap with a direct path to the battery must be
used. This path may be provided by way of a direct
engine ground to the frame.
All grounds should be tight and free of corrosion. The
engine alternator must be grounded to the negative
"-" battery terminal with a wire that is adequate to
handle the full charging current of the alternator.
