Grounding Practices

g00771448Illustration 11Typical example

Grounding Stud To Battery Ground


Engine Electronics


Typical example

Alternate Grounding Stud To Battery Ground

Proper grounding for the engine electrical systemis necessary for optimum engine performanceand reliability. Improper grounding will result inuncontrolled electrical circuit paths and in unreliableelectrical circuit paths.

Uncontrolled electrical circuit paths can result indamage to main bearings, to crankshaft bearingjournal surfaces, and to aluminum components.

Engines that are installed without engine-to-frameground straps can be damaged by electricaldischarge.

To ensure that the engine and the engine electricalsystems function properly, an engine-to-frame groundstrap with a direct path to the battery must be used.This path may be provided by way of a starting motorground, a starting motor ground to the frame, or adirect engine ground to the frame.

All grounds should be tight and free of corrosion. Theengine alternator must be grounded to the negative“-” battery terminal with a wire that is adequate tohandle the full charging current of the alternator.
