CHECK FOR SHORT CIRCUIT
(a) Remove the blown fuse and eliminate all toads from
the fuse.
(b) Connect a test bulb in place of the fuse.
(e) 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 oft (or Disconnect SW 2)
(d) Disconnect and reconnect the connectors while
watching the test bulb.
The short lies between the connector 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. (c) Use a volt/ohmmeter with high impedance (10 k

/V
minimum) for troubleshooting of the electrical circuit.

1. INSPECT RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity between
terminals 1 and 3.
(b) Check that there is continuity between terminals 2 and
4.
(c) Check that there is no continuity between terminals 4
and 5.
If continuity is not as specified, replace the relay.
2. INSPECT RELAY OPERATION
(a) Apply battery voltage across terminals 1 and 3.
(b) Using an ohmmeter, check that there is continuity between
terminals 4 and 5.
(e) Check that there is no continuity between terminals 2
and 4.
If operation is not as specified, replace the relay.

1. TURN IGNITION SWITCH ºONº
Check that the fan stops.
If not, check the cooling fan relay and water temperature
switch, and check for a separated connector or severed
wire between the cooling fan relay and water temperature
switch.
2. DISCONNECT WATER TEMPERATURE SWITCH
CONNECTOR
Check that fan rotates.
If not, check the cooling fan relay, fan motor, engine main
relay and fuse, and check for a short circuit between the
cooling fan relay and water temperature switch.
