BREAKAWAY DEVICE
Should your trailer become completely disconnected
while being towed, the breakaway device is designed to
actuate the trailer brakes and bring it to a stop, preventing
a runaway trailer. The switch has a pull-pin linked to the
tow vehicle with a steel cable; the cable pulls the pin free.
This causes two contacts in the device to go together,
immediately closing the circuit between the trailer battery
and the trailer brakes.
CAUTION: Never tow a trailer without the trailer battery
being hooked up and fully charged. Attach the breakaway
lanyard cable so it is longer than the safety chain. When
connected to the vehicle, the pull on the pin is in a straight
line with the cable. Do not hook the cable over the trailer
ball.
