Circuit which energizes by applying a ground, usually through a control module.
ground effect
Glossary “ground effect” Definition:
The reduced air pressure under a vehicle that allows the normal pressure above the vehicle to push the vehicle downward, providing a better grip on the road surface.
ground electrode
Glossary “ground electrode” Definition:
Part of the lower end of the spark-plug shell making up the electrode gap, providing a path for current flow while jumping the gap.
