Downloaded from www.Manualslib.com manuals search engine 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.
Downloaded from www.Manualslib.com manuals search engine as a screwdriver handle or pliers. Replace the oir cleaner and attempt to start the engine in the normal manner. (E) If the car will start but stalls when hot or has a rough idle, you can suspect a faulty IDLE ADJUSTMENT, a malfunctioning AUTOMATIC CHOKE or an extremely dirty and blocked AIR CLEANER ELEMENT. Replace paper element air cleaner if necessary. Idle adjustment or automatic choke service (other than that outlined in paragraph 0 above) should be performed by your Chevrolet
Dealer. If the above Fuel System checks and the checks suggested under
the Electrical System following do not correct the malfunction, it is recommended that you turn to your Authorized Chevrolet Dealer
for further checks, adjustments or repairs. ELECTRICAL SYSTEM If when the ignition key is turned to "Start", the engine will not turn' over, yOu have good reason to suspect electrical trouble. NOTE: Never'remove Delcotron bat lead without first disconnecting battery ground cable. IF) When there is no response at all to attempts to start the car,
check the obvious-your AUTOMATIC TRANSMISSION SELECTOR LEVER must be in Neutral or Park position (manual transmission
must have clutch depressed all the way to floor) before the engine
can be starfed. Turning the IGNITION SWITCH rapidly back and forth several times will sometimes correct a poor internal switch
contact.
(GI The BATTERY may be discharged. If so, lights will be dim and the horn will have a poor tone if it will blow at all.
Usually a garage recharge will be necessary to return the battery to operation. Occasionally, however, a long drive will recharge the battery. . , •
NOTE: If the baHery is determined to be dead, and for no apparent reason, have your :Aflthori~ed Chevrolet Dealer check the baHery, the GENERATOR and the VOLTAGE REGULATOR.
GENERATOR trouble shqiJld already have been indicated by
69
the generator indicator light on the instrument panel.
POOR BATTERY CONNECTIONS may be suspected if the car has operated properly a short time before and now not even the horn will operate. Check both ends of both battery cables. If the connections are corroded, a car may sometimes be restored to operation by removing all cable ends, scraping all contacting surfaces
clean with a pen knife, and reassembling. If the cables are broken,
they must be replaced. The power supply should now be restored unless-the battery is dead.
(HI If, however, the lights and horn work properly but the starter will still not turn over, check the STARTER connections. A "click" from the starter solenoid indicates that the wiring to the starter is properly installed. If the wiring seems to be clean and tightly installed, the trouble is probably in the starter itself and should be referred to your Authorized Chevrolet Dealer.
When the engine will "turn over" but will not start, the following
items may be checked along with the Fuel Systems Checks listed previously.
(II With a clean dry cloth wipe the ce-amic portions of the spark plugs dry. In particularly damp or rainy weather dampness may be the cause of not starting, espe
cially when the engine is cold.
(JI Check the cables at the top
of the distributor and coil as well as each spark plug cable for
tightness.
(KI If the car will still not start,
check for spark at the spark plugs in the following manner: Pull one of the spark plug
wires off its spark plug. Insert a
short piece of bare wire (such as Distributor and Coli Cables
