TROUBLE SHOOTING
Q: When an external charger is connected the charging LED on the front panel
does not turn on?
A: The charging LED only turns on when the internal battery is charged by the towing
vehicle or the house battery.
Q: When the test button is pressed the brake lights do not activate/illuminate
yet the battery status LED is green.
A: Check the brake light fuse and continuity of the cable connection. Replace fuse and
tighten the connection if required.
Q: When the test button is pressed the brakes do not lock yet the battery status
LED is green.
A: Measure the voltage at the blue cable. There should be more than 11.5V applied to
the blue wire if the battery status LED is green. If no voltage or voltage is below
11.5V, check the continuity of the cable connection. Tighten the connection if
required. If the connection and measured voltage is fine, bring the trailer to repair
shop to check the electric brakes as soon as possible.
Q: The pin was pulled from the ‘Breakaway Switch’ but the brakes did not
engage/lock.
A: Check if the pin was broken. If yes, replace the breakaway switch. Check if the
orange wires are well connected to the black wires of the breakaway switch.
Check if the orange wires are short-circuited when the pin is pulled. If not, replace
breakaway switch. If yes, measure the voltage at the blue cable. There should be
more than 11.5V applied to the blue wire if the battery status LED is green. If no
voltage or the voltage is below 11.5V, check the continuity of the cable connection.
Tighten the connection if required. If the connection and measured voltage is fine,
bring the trailer to repair shop to check the electric brakes as soon as possible.
Q: When the test button is pressed no LED illuminates.
A: Check if the internal battery terminals are connected well with female blade
terminals. If yes, replace the battery as soon as possible.
Q: When the test button is pressed the battery status LED momentarily turns
green and red.
A: The internal battery is below its full charge level. Charge the battery as soon as
possible before starting to use the trailer. If battery does not hold charge, replace
with a new battery
Q: When the tow vehicle is running and the trailer plug is engaged the charging
LED is not turned on.
A: Check if the internal battery terminals are connected well with female
blade terminals.
