How
INSPECTION
1. Visual and aural checks
Check relay operation, blower motor rotation, light illumina-
tion, etc. visually or aurally. The flow of current is invisible
but can be checked by the operation of the parts.
2. Simple checks
For example, if a headlight does not come on and a faulty
fuse 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 and
read 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.
