1982 CHEVROLET CAMARO check engine

GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 352
To prevent serious damage to the alte
rnator and the rest of the charging
system, the following precauti ons must be observed:
• Never reverse the battery connections.
• Booster batteries for starting must be connected properly: positive-to-
positive and negative-to-ground.
• Disconnect the battery cables before using a fast charger; the charger
has a tendency to force current through the diodes in the opposite
direction for which they were designed. This burns out the diodes.
• Never use a fast charger as a booster for starting the vehicle.
• Never disconnect the voltage regulator while the engine is running.
• Avoid long soldering times when replacing diodes or transistors.
Prolonged heat is damaging to AC alternators.
• Do not use test lamps of more t han 12 volts (V) for checking diode
continuity.
• Do not short across or ground any of the terminals on the AC alternator.
• The polarity of the battery, alter nator, and regulator must be matched
and considered before making any elec trical connections within the
system.
• Never operate the alternator on an open circuit. make sure that all
connections within the circ uit are clean and tight.
• Disconnect the battery terminals when performing any service on the
electrical system. This wil l eliminate the possibility of accidental reversal
of polarity.
• Disconnect the battery ground cable if arc welding is to be done on any
part of the car.
CHARGING SYSTEM TROUBLESHOOTING
There are many possible ways in whic h the charging system can malfunction.
Often the source of a problem is diffi cult to diagnose, requiring special
equipment and a good deal of experience. However, when the charging system
fails completely and causes the dash boar d warning light to come on or the
battery to become dead the following items may be checked:
1. The battery is known to be good and fully charged.
2. The alternator belt is in good condition and adjusted to the proper
tension.
3. All connections in t he system are clean and tight.
REMOVAL & INSTALLATION

3. Disconnect all wiring from the star
ter solenoid. Replace each nut as the
connector is removed (as thread sizes differ from connector to
connector). Note or tag the wiring positions for installation.
4. Remove the bracket from the st arter and the two mounting bolts. On
engines with a solenoid heat shield, remove the front bracket upper bolt
and detach the bracket fr om the starter.
5. Remove the front bracket bolt or nut. Lower the starter front end first, and
then remove the unit from the car.
To install: 6. Position the starter into place and se cure it with the front bracket bolt and
nut. Torque the two mounting bolts to 25-35 ft. lbs.
CAUTION - If shims were removed, they must be replaced to ensure proper
pinion-to-flywheel engagement.
7. On engines with a solenoid heat shield, attach the bracket to the starter.
Install the bracket to the starter and the two mounting bolts. Install the
front bracket upper bolt.
8. Connect all wiring to the starte r solenoid and tighten the nuts.
9. Lower the vehicle.
10. Connect the negative battery cable.
SOLENOID REPLACEMENT 1. Remove the screw and washer from the motor connector strap terminal.
2. Remove the two solenoid retaining screws.
3. Twist the solenoid housing clockwis e to remove the flange key from the
keyway in the housing. Then remove the housing.
4. To re-install the unit, place the re turn spring on the plunger and place the
solenoid body on the driv e housing. Turn counterclockwise to engage the
flange key. Place the two retaining screws in position and install the
screw and washer which secures the strap terminal. Install the unit on
the starter.

MECHANICAL ENGINE
REMOVAL & INSTALLATION
In the process of removing the engine, you will come across a number of steps
which call for the removal of a separ ate component or system, such as
"disconnect the exhaust system " or "remove the radiator." In most instances, a
detailed removal procedure can be found elsewhere in this repair guide.
It is virtually impossible to list each individual wire and hose which must be
disconnected, simply because so many different model and engine
combinations have been manufactured. Careful observation and common
sense are the best possible approaches to any repair procedure.
Removal and installation of the engine ca n be made easier if you follow these
basic points:
• If you have to drain any of the fl uids, use a suitable container.
• Always tag any wires or hoses and, if possible, the components they
came from before disconnecting them.
• Because there are so many bolts and fasteners involved, store and label
the retainers from com ponents separately in muffin pans, jars or coffee
cans. This will prevent conf usion during installation.
• After unbolting the transmission or trans axle, always make sure it is
properly supported.
• If it is necessary to disconnect t he air conditioning system, have this
service performed by a qualified tec hnician using a recovery/recycling
station. If the system does not have to be disconnected, unbolt the
compressor and set it aside.
• When unbolting the engine mounts, a lways make sure the engine is
properly supported. When removing t he engine, make sure that any
lifting devices are properly attached to the engine. It is recommended
that if your engine is supplied with lifting hooks, your lifting apparatus be
attached to them.
• Lift the engine from its compartment sl owly, checking that no hoses,
wires or other component s are still connected.
• After the engine is clear of the compar tment, place it on an engine stand
or workbench.
• After the engine has been removed, y ou can perform a partial or full
teardown of the engine using the procedur es outlined in this repair guide.
