3.6 Testing the Breakaway System (Electric Brakes)
Requirements
Voltmeter
Battery charger or backup battery (charged)
When
Test the breakaway system:
Before towing
Monthly if the machine is not in service
Procedure
Perform the following procedure to test the breakaway system.
NOTICE: Disconnect the trailer wiring plug from the tow vehicle before testing.
Failure to do so will result in severe damage to the electronic brake control.
1. Connect the machine/trailer to the tow vehicle.
2. Disconnect the trailer wiring plug (a) from the tow vehicle.
3. Pull the breakaway pin (b) out of the brake switch (c) (to activate the brakes)
and attempt to tow the machine/trailer at a very slow speed (less than 5 mph (8
km/hr)). When activated, a properly working breakaway system will cause
substantial drag on the trailer wheels and may even cause the trailer wheels to
lock.
4. Stop the tow vehicle.
