BODY ELECTRICAL SYSTEM
(c) Use a volt/ohmmeter with high impedance (10 k/V
minimum) for troubleshooting of the electrical circuit.
BULB CHECKING
(a) Remove the bulb.
(b) There should be continuity between the respective
terminals of the bulb together with a certain amount
of resistance.
(c) Apply the 2 leads of the ohmmeter to each of the
terminals.
(d) Apply battery positive voltage and check that the bulb
lights up.
SHORT CIRCUIT CHECK
(a) Remove the blown fuse and eliminate all loads from
the fuse.
(b) Connect a test bulb in place of the fuse.
(c) Establish conditions in which the test bulb comes on.
Example:
A–Ignition SW on
B–Ignition SW and SW 1 on
C–Ignition SW, SW 1 and Relay on (Connect the
Relay) and SW 2 off (or Disconnect SW 2)
(d) Disconnect and reconnect the connectors while wat–
ching the test bulb. The short lies between the con–
nector where the test bulb stays lit and the connector
where the bulb goes out.
(e) Find the exact location of the short by lightly shaking
the problem wire along the body.
