or property damage. All General
Motors cars have negative-ground
electrical systems and can be used
to jump start
one another. If you
cannot determine how the other
vehicle is grounded (by checking
specifications in the owner's man-
ual, etc.) we recommend that you
attempt no jump starting with that
vehicle.
Jump Starting with
Auxiliary (Booster) Battery
Both booster and discharged
battery should be treated carefully
when using jumper cables. Follow
exactly the procedure outlined be-
low, being careful not to cause
sparks:
1. Set parking brake and place
automatic transmission in
"PARK" (neutral for manual
transmission). Turn off lights,
heater and other electrical loads.
2. Remove vent caps from both
the booster and the discharged
batteries. Lay a cloth over the
open vent wells of each battery.
These two actions help reduce
the explosion hazard always
present in either battery when
connecting "live" booster bat-
teries to "dead" batteries.
3. Attach one end of one jumper
cable to the positive terminal of
the booster battery (identified
by a red color,
"+"
or "P" on
the battery case, post or clamp)
and the other end of same cable
to positive terminal of discharged
battery. Do NOT permit cars to
touch each other, as this could
'establish a ground connection
and counteract the benefits of
this procedure.
4. Attach one end of the remaining
negative cable to the negative
terminal (black color, "-" or
"N") of the booster battery, and
43
the other end to the' de1cotron
mounting bracket (see illustra-
tion) of your 1973 Monte Carlo
(do not connect directly to neg-
ative post of dead battery) -
taking care that clamps from
one cable do not inadvertently
touch the clamps on the other
cable. Do not lean over the
battery when making this con-
nection.
Reverse this sequence exactly
when removing the jumper cables.
Re-install vent caps and throw
cloths away as the cloths may have
corrosive acid on them.
