BATTERY CHARGING
If the system measures voltage less than 13.5V, the charging circuit will provide
maximum charging current to a 12V 7Ah Battery until the battery is fully charged to
13.5V. During the operation the system provides a ‘Trickle Charge’ to maintain battery
voltage. An external charger can be used.
When battery voltage is under 6V, the internal circuit will not activate when the ‘Test’
button is pressed and the whole test circuit will have no power and will not activate
either the green or red LED. This will indicate a flat battery.
EXTERNAL CHARGING
The Sure Brake Breakaway Kit has the
option to charge the battery using an
external battery charger. Just connect
the positive clamp/cable of the external
charger to the red post and the negative
clamp/cable of the external charger to
the black post.
MOUNTING
1. Breakaway Switch: Position the Breakaway Switch on the drawbar of the trailer
such that it allows the cable to reach the tow vehicle’s hitch chain safety eyelets.
It must be mounted so the breakaway/plunger lanyard is facing the tow vehicle,
per the diagram below. This is critical for proper engagement of the switch.
Drill a 7mm hole in the trailer drawer bar frame to mount the Breakaway Switch
once you’ve located the mounting location. Use an M6 bolt and lock nut (both not
provided) to mount the Breakaway Switch to the trailer. Note: Use caution
when drilling the hole that there are no wires or other objects behind the
mounting surface. Note: Take care not to over-tighten the bolt because the
Breakaway Switch needs to pivot.
2. Battery Case: Find a suitable location on the trailer frame to mount the Breakaway
battery case. It should be mounted under cover or in an area protected from all
weather conditions.
