Coupling To The Tow Vehicle 4.3.1.7 Test Electric Brakes If your trailer has electric brakes, your tow vehicle will have an electric brake controller that sends power to the trailer brakes. Before towing the trailer on the road, you must operate the brake controller while trying to pull the trailer in order to confirm that the electric brakes operate. While towing the trailer at less than 5 mph, manually operate the electric brake controller in the tow vehicle. You should feel the operation of the trailer brakes. If the trailer brakes are not functioning, the brake system MUST be evaluated to determine the cause of the problem and corrective action MUST be taken before the trailer is used. Take the unit to your dealer or a qualified brake specialist. Use this procedure each time you tow your trailer to check your surge brake system operation. 4.3.1.8 Test Electric Breakaway Brakes The breakaway brake system includes a battery, a switch with a pullpin and lanyard, and a breakaway brake controller. Read and follow the instructions here as well as the instructions that have been prepared by the breakaway brake manufacturer. If you do not have these instructions, contact your dealer for assistance. The breakaway brake system battery will trickle charge from the tow vehicle. Dump trailers and trailers with 12 volt hydraulic pumps will use the hydraulic pump battery for the breakaway brakes and will not be equipped with the battery charger shown in figure below. If the electrical system on your tow vehicle does not provide power to the battery, you must periodically charge the battery with a commercial battery charger to keep the battery charged. Dump trailers and trailers with 12 volt hydraulic pumps have an on-board battery maintainer/charger. See the Accessories section. The “Charging” lamp (1) will be illuminated when the battery is receiving a charge from the tow vehicle. Press the “Test” button (2) to test the battery level of charge. Do not tow trailer if the battery requires recharging. A discharged breakaway brake battery will not activate the brakes if the trailer uncouples from the tow vehicle. The battery must be fully charged before towing trailer 64 Breakaway Brake Battery Charger
