5. The radiator fan reversal switch terminals are identified in
circuitry of the radiator fan reversal switch is shown in the
(page 6–19). With the use of a multimeter (ohms setting), test the switch
functions to determine if the continuity exists between the various terminals
for each switch position. Check the continuity between the switch terminals.

6. Replace the radiator fan reversal switch if the testing determines it is
damaged.
7. If the radiator fan reversal switch testing is correct and a circuit problem still
exists, check the wire harness; refer to the Electrical Schematics and Wire
Harness Drawings/Diagrams in
8. After you complete the testing, connect the machine wire harness connector
to the radiator fan reversal switch.
9. Install the dash panel to the steering column; refer to
Assembly (page 7–7).
10. Connect the battery negative (-) cable to the battery.
