Electrical Requirements
The blue wire from the in-cab electronic brake control is
connected to the blue wire on the actuator. The yellow wire from
the actuator is connected to the cold side of the trailer emergency
breakaway switch. Under no circumstances should the blue
wire and the yellow wire be connected together, nor should
the blue wire ever be grounded.
Requires an In-Cab Electronic Control – The Dexter E/H
actuator is intended to be used with an in-cab electronic brake
controller. The unit will operate with a wide variety of controllers
but provides optimum performance when used with a Dexter
electronic brake controller. The in-cab controller must have an
output capacity of at least 5 amps for proper operation of the
Dexter E/H actuator.
CAUTION
It is the responsibility of the end user to ensure that their
in-cab electronic controller is compatible with the Dexter
E/H actuator. Dexter Axle attempts to provide
compatibility with most controllers available, but is
unable to anticipate design changes that might be
introduced by the various controller manufacturers.
Electrical Connections – Make sure all electrical connections
are clean, dry, weather tight, and secure to prevent damage to
the wiring from dragging or becoming entangled with foreign
objects. A dedicated ground connection between the tow vehicle
and trailer is also required.
Breakaway Battery Requirement – To comply with federal
requirements, the trailer must be equipped with a breakaway
switch and battery. The breakaway battery needs to have a
minimum capacity of 9 amp hours and needs to be maintained in
a fully charged condition at all times. The breakaway battery
should be checked for proper charge level before every use.
Charging the Breakaway Battery – The breakaway battery must
be kept fully charged at all times in order to function properly. Use
only those breakaway battery kits that include a charging device.
Do not attempt to charge the breakaway battery directly from the
tow vehicle without the appropriate charging device.
