1997 CHEVROLET SUBURBAN radio

3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlets. Turn
off all lamps
that aren’t needed, and radios. This will avoid sparks
and help save both batteries. And
it could save
your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
4. Open the hoods and locate the batteries. Find the
positive
(+> and negative (-) terminals on each battery.
~ If your vehicle has air conditioning, the auxiliary
electric fan under the hood can start up even
when the engine is not running and can injure
you. Keep hands, clothing and tools
away from
any underhood electric fan.
I
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use
a flashlight if
you need more light.
Be sure the batteries have enough water.
You
don’t need to add water to the Delco Freedom@
battery (or batteries) installed in every new
GM
vehicle. But if a battery has filler caps, be sure
the right amount
of fluid is there. If it is low, add
water to take care of that first.
If you don’t,
explosive gas could be present.
Battery fluid contains acid that can burn you.
Don’t get it on you.
If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.

Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and closes.
This protects the circuit until the current load returns
to
normal or the problem is fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links in the wiring itself. This
Instrument Panel Fuse Block
The fuse block access door
is on the driver’s side edge
of the instrument panel. Pull
off the cover to access the
fuse block.
You can remove fuses with
a fuse extractor. The fuse
extractor is mounted to the
fuse block access door.
greatly reduces the chance of fires caused by electrical
problems. See “Fuses and Circuit Breakers” in the Index
for more information.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure
you
replace a bad fuse with a new one of the identical size
and rating.
If you ever have a problem on the road and don’t have a
spare fuse, you can “borrow” one that has the same
amperage. Just pick some feature
of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
To remove fuses if you don’t have a fuse extractor, hold
the end of the fuse between your thumb and index finger
and pull straight out.
You may have spare fuses attached to the inside of
the fuse block access door. These can be used to
replace a bad fuse. However, make sure that it is the
correct amperage.
