2000 CADILLAC CATERA relay

6-57 Power Distribution Fuse Block
This fuse block is attached to the engine compartment
relay center located on top of the battery. Simply lift the
lid to open. If you have any questions about the power
distribution fuse block, consult your dealer.
Please note that if a power loss has occurred, such as
disconnecting the battery or removing the Maxi Fuses
in the power distribution fuse block, there are steps that
must be followed to calibrate the Electronic ThrottleControl (ETC). If these steps are not done, the engine
will not run properly. For information regarding these
steps, see ªBatteryº earlier in this section.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires
caused by electrical problems.
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. 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.
There are two fuse blocks in your vehicle: the
instrument panel fuse block and the engine
compartment relay center.
