Do not lay one ground lug directly on top of the other. This
type of connection can become loose due to compression
of the metal lugs. Sandwich the first lug between a star
washer and a nut with a captive star washer. After
tightening the nut, sandwich the second lug between the
first nut and a second nut with a captive star washer.
