towing the cabra
–
The parking brakes on the Cabra are fail-on. If there is no power
to either parking brake, they are on. There is an electromagnetic brake on the front of
each motor. The only way to get power to the parking brake is for the motor controller to
command power to it, so if the controller is not working the brake will be on. If the Cabra
must be towed a short distance and the controllers are working, a driver can sit in the
driver seat with the Cabra in drive while someone tows the Cabra. If there is no power,
the brakes must be removed. To remove the brakes, first
make sure the tires are
properly chocked,
since once the brakes are removed, there are no parking brakes.
Disconnect the red battery cable connector to ensure the wires you are working with are
de-energized. Disconnect the brake wires at the brake, then use the 10 mm wrench from
the provided tool kit to remove the 3 bolts on each brake and pull the brake away from
the motor and remove. Once this is accomplished on both parking brakes, the Cabra can
be towed with the power off.
Never tow the Cabra faster than 35 MPH as this will
ruin the motors and axle gearboxes.

vehicle will not turn on
–
First make sure you are turning the key all the way to the
right for a second to wake it up. If still no power, check the voltage on the 12-volt battery
to make sure it is at least 12 volts. If voltage is below 12 volts, the BMS cannot wake up.
I
t can be “jumped” by
connecting to any 12-volt battery. It only takes a little power to
wake up the BMS and start the DC/DC converter charging up the 12 Volt battery. The
vehicle should run in this condition but if the 12-volt battery will not charge up and
maintain 12 volts it will need to be replaced.
