Grounding Locations
You must connect the equipment DC ground lug to a grounding
point—usually the vehicle’s chassis or DC negative bus ground—
using recommended copper wire size (if insulated then green
insulation with or without one or more yellow stripes) or larger.
Make sure to tighten the bolt on the DC ground lug to a torque of
23 in-lb (2.6 N-m) of force. Apply an anti-corrosion compound to
the copper wire prior to connecting to the DC ground lug.
For recommended equipment ground cable size, see below.
