NOTICE
The eCascadia contains two low-voltage
systems: 24V and 12V. These directions detail the
steps to charge or ’jump start’ the 12V batteries.
On an eCascadia, the 12V batteries must be
operational for the high-voltage batteries to
activate.
To jump start another vehicle from an eCascadia,
both the 12V and the high-voltage (HV) batteries
on the eCascadia must be active. An active high-
voltage system is necessary to keep the low-
voltage (12V) charge at a sufficient level to
provide the ’jump.’
To jump start another vehicle from an eCascadia,
follow the directions below, switching out the
other vehicle for ’the eCascadia’ and ’the
eCascadia’ for the ’the power source.’
Only use jumper cables approved for use with
heavy duty vehicles. The use of inadequate or
damaged jumper cables may damage both
vehicles.
Do not connect an eCascadia to a vehicle with a
different operating voltage. Electronic devices on
both vehicles can be damaged if vehicles with
different operating voltages are connected.
NOTE: eCascadia vehicles are equipped with
under-hood jump start posts;
always connect to
these posts instead of the batteries.
When using jumper cables, follow the instructions
below.
1. Apply the parking brakes and turn off the lights
and all other electrical devices.
2. Open the hood.
NOTICE
Always connect the battery, jumper cables, and
charger correctly (positive-to-positive, negative-
to-negative). Connecting a charging device
backwards (positive-to-negative or negative-to-
positive) will damage the vehicle.
3. Connect one end of a 12V positive (+) jumper
cable to the 12V positive (+) post on the electric
vehicle distribution module (EVDM) as shown in
Fig. 19.4.
4.
Connect the other end of the 12V positive (+)
jumper cable to the 12V positive (+) connection
on the power source providing the jump start.
The power source may be a battery, external
battery charger, or the jump start post of a
vehicle.
WARNING
Do the next step exactly as instructed and do not
allow the clamps of one cable to touch the
clamps of the other cable. Otherwise, a spark
could occur near a battery, possibly resulting in
severe personal injury from explosion or acid
burns.
5. Connect one end of the negative (-) jumper cable
to the negative (-) connection on the power
source providing the jump start.
