voltage as the engine system voltage.
2 Connect the red positive cable to the plus (+)
terminal on the discharged battery and then to the
plus terminal on the auxiliary battery.
3 Connect the black start cable to the minus (–)
terminal on the auxiliary battery and to a place a
little distance away from the discharged battery,
e.g. the start motor's negative terminal.
WARNING!
The black jumper cable (–) must never come in contact
with the positive connection on the starter motor.

surfaces.
