L.E.D STATUS INDICATORS
‘Charging’ LED: Illuminates Green when the internal battery is being charged by the
tow vehicle or house battery (auxiliary battery at the caravan/trailer).
‘Good’ LED: Illuminates Green when the internal battery has enough charge.
‘Low’ LED: Illuminates Red when the internal battery needs charging before use.
NOTE:
The LED will not turn on if external battery charger is connected to the DC terminals.
Please check the battery charger display for internal battery charging status.
INTERNAL BATTERY TEST
Push the ‘Test’ button on the front of the unit to check the internal battery condition.
The trailer brakes and brake lights will activate when the ‘Test’ button is pressed, this
operational load is applied each time the ‘Test’ button is pushed. If the battery voltage
is above 11.5V, a ‘green’ LED is illuminated. If the battery voltage drops under 11.5V, a
‘red’ LED is illuminated. If the battery is under 6V neither LED indicator will be illuminate.
‘Good’ LED – Illuminates Green when internal battery has enough charge.
‘Low’ LED – Illuminates Red when the internal battery needs charging before use.
No LED turns On – The internal battery is flat or heavily discharged. Try to charge the
battery fully. Repeat the battery test. If LOW LED turns Red or no LED turns on, replace
the internal battery.
NOTE:
1. Prior to replacing the internal battery, disconnect the trailer connector from the
tow vehicle.
2. Check the Sure Break breakaway system periodically to ensure proper secure
electrical connections.
3. Check that the breakaway switch cable isn’t damaged from dragging on the ground
and is free from obstruction.
4. Internal battery fuse is rated at 30A. Brake light fuse is rated at 10A.
