INSPECTION OF CIRCUIT WITH TESTER
If a diode is built in the circuit, perform continuity test by
changing the polarities of the measuring terminals.
In case of a general type tester, ensure that continuity exists
when the negative (–) lead of the tester is connected to the
positive (+) side of the diode; the positive (+) lead of the
tester to the negative (–) side of the diode. Also ensure that no
continuity exists when the polarities are changed.
Since some testers have different polarities, be sure to read
the instruction manual of a tester to be used for the check
before using it.
The inspection procedure for light emitting diodes (LED) is the
same as normal diodes. However, there may be cases where
the LED emits no light, unless a tester with LED check mode
is used. If an adequate tester is not available, apply the
battery voltage to the LED and ensure that the LED emits
light.
INSPECTION OF SHORT CIRCUIT
(1) Remove a melt fuse or fusible link.
(2) Disconnect all connectors for loads being applied to the
melt fuse.
(3) Connect a test lamp at the position where the melt fuse or
fusible link was installed.
(4) Search for the short circuit by providing the minimum
conditions which make the test lamp glow.
(5) Perform repairs or wiring harness replacement, as
required.
