Electrical Circuit Grounding
When installing the crane, always locate a good source for grounding the circuit. A majority of
electrical failures are due to poor grounding. Poor grounding can cause intermittent operation of the
equipment, electrical component failures and cause the equipment to not operate at all.
Chassis manufacturers usually will have a ground strap which ties into the truck frame from the
battery, but it is always a good idea to check each individual model to verify where the ground is
located. Never use the mechanic body as a ground source. Make sure the electrical grounds are
routed to either the chassis frame rail or the chassis’s main grounding source.
Stellar provides a stud (PN 40992) for grounding the crane to the chassis frame rail:
Drill the hole to the frame rail in accordance with the chassis body builder’s
guide.
• Hole size: 21/64”
• The hole location should allow for the shortest length of ground wire while keeping enough slack
for exibility.
• Be sure to grind the frame rail around the hole to ensure a proper ground connection.
• Frame rail thickness may require additional at washers (as shown).
• Use an electrical coating on hardware to prevent corrosion.
