be mounted to a vehicle
framing member to provide optimum ground.
Ground Cable Corrosion:
When mounting ground
cables, remove undercoating, dirt, rust, etc. from
framing member around
mounting holes (minimum
5/8” diameter area). Apply protective coating to
mounting holes to prevent
corrosion. Failure to do
so will void warranty of
