Z1680225
INSPECTION1. Visual and aural checks
Check relay operation, blower motor rotation, light illumina-d
tion, etc. visually or aurally. The flow of current is invisiblebut can be checked by the operation of the parts.
2. Simple checks
For example, if a headlight does not come on and a faultyfuse or poor grounding is suspected, replace the fuse
with a new one or ground the light to the body by a jumper
wire to determine which part is responsible for the problem.3. Checking with instruments
Use an appropriate instrument in an adequate range andread the indication correctly. You must have sufficient
knowledge and experience to handle instruments correctly.
INSPECTION INSTRUMENTS
In inspection, make use of the following instruments.1. Test lights
A test light consists of a 12 V bulb and lead wires. It
is used to check voltages or short circuits.
2. Self-power test light
A self-power test light consists of a bulb, battery and lead
wires connected in series. It is used to check continuity
or grounding.

This figure illustrates a complex switch. The continuity
between terminals at each position is as indicated in the
table below.4th stage
CHECKING RELAYS1. When current flows through the coil of a relay, its core
is magnetized to attract the iron piece, closing (ON) the
contact at the tip of the iron piece. When the coil current
is turned off, the iron piece is made to return to its original
position by a spring, opening the contact (OFF).
2.By using a relay, a heavy current can be turned on and
off by a switch of small capacity. For example, in the circuit
shown here, when the switch is turned on (closed), current
flows to the coil of the relay. Then, its contact is turned
on (closed) and the light comes on. The current flowingat this time to the switch is the relay coil current only
and is very small.3. The relays may be classified into the normal open type
and the normal close type by their contact construction.
NOTE
The deenergized state means that no current is flowing
through the coil and the energized state means that current
is flowing through the coil.
