CAUSES FOR BLOWN FUSE
There are three causes for blown fuse which can be
inspected after blown.
1. Over-current due to a short circuit
Can occur due to mechanical fault or electrical fault.
For example, high current is applied to the motor if
the wiper blades are frozen on the windshield.
(The cause of blown fuse should be determined be-
fore replacing the fuse.)
2. Aged fuse
As current is cycled through fuses from ON to OFF
repeatedly, the fuse's temperature rises and drops
and it is eventually blown. If the fuse is blown, replace
it immediately.
3. Poor contact (heat produced)
If the fuse is poorly seated, the fuse will blow due
to the heat by resistance. Polish the fuse contact
surface with sandpaper to prevent this problem.

CHECKING CIRCUITS
In general, it is not hard to inspect an electric circuit
in a logical and organized way. It is very import to col-
lect as much information as possible before starting
inspection. Also, you should understand the system's
operation and be ready to follow proper inspection pro-
cedures using proper devices.
If necessary, the inspector can shake wiring or electric
parts gently while testing them.
Open circuit: There is a disconnected part in a
circuit.
Short circuit: There are two types of short circuit.
- Short to circuit:
The resistance changes as a circuit
is contacted to another circuit.
- Short to ground:
A circuit is contacted to ground
or ground part.
