REMOVAL AND REPI
Procedures apply to all models unless otherwise
specified.
BATTERY
1. Remove positive and negative battery cables,
2. Remove battery clamp.
3. Remove battery keeping in an upright position.
4. If desired, remove battery tray.
5. To replace, reverse removal procedures.
NOTE: On Tempest models it is important to
route cable as shown in Fig. 12-10.
BATTERY CABLE
Battery Cable routing is shown in Figs. 12-11 for
Pontiac and 12-12 for Firebird.
FUSIBLE LINK
1. Disconnect battery.
2. Locate burned out link.
NOTE: Link may be recognized on Pontiac or
Tempest V-8 models as a loop of wire (approxi-
MENT PROCEDURES
mately 5" in length) protruding from engine wiring
harness along left rocker arm cover where har­
ness breaks out for alternator. On Pontiac or
Tempest 6-cylinder models loop will be located
at breakout for voltage regulator from engine wir­
ing harness. On Firebird models two links are
used, one from voltage regulator and one from +
battery to junction block.
3. Strip away all melted harness insulation.
4. Cut burned link ends from circuit wire.
5. Strip (approximately 1/2") back circuit wire
that new link is to be soldered to.
6. Using fusible link 4 gauges smaller than pro­
tected circuit (approximately 10" long), solder new
link into circuit.
CAUTION: Use only resin base solder. Under no
circumstances should an acid base solder be used
nor should link be connected in any other manner
except by soldering.
7. Tape soldered ends securely using suitable
electrical tape.
8. After taping wire, tape harness leaving an ex­
posed loop of wire of approximately 5" in length.
9. Connect battery.
