Welding Precautions
Take precautions before electrically welding any portion of the unit or the
vehicle to which it is attached. Verify that welding currents are not allowed to
flow through the unit’s electronic circuits.
Observe the following precautions when welding to avoid damaging
electronic components.
• If the microprocessor has a power switch, turn it OFF before connecting
or disconnecting the battery.
• Disconnect power to the unit.
• Disconnect all wire harnesses from the microprocessor.
• If there are any electrical circuit breakers in the control box, switch them
OFF.
• Close the control box.
• Components that could be damaged by welding sparks should be
removed from the unit.
• Use normal welding procedures, but keep the ground return electrode as
close to the area being welded as practical. This will reduce the likelihood
of stray welding currents passing through any electronic circuits.
