Blower Resistor - Kubota M6040 NARROW Workshop Manual

M6040, M7040Narrow, WSM

(2) Blower Resistor

Temperature Control Dial Checking
1. Turn the temperature control dial counterclockwise till it stops
(at "COOL" position).
2. Measure the voltage with a voltmeter across the terminal b and
terminal d. Make the following measurement with the terminals
connected.
3. Turn the main switch to "ON" position.
4. Check that an output voltage is approximately 10 V when
turning the temperature control dial clockwise till it stops
("WARM" position).
5. Turn the main switch back to "OFF" position.
6. Turn the temperature control dial clockwise till it stops
("WARM" position).
7. Measure the voltage with a voltmeter across the terminal d and
terminal b. Make the following measurement with the terminals
connected.
8. Turn the main switch to "ON" position.
9. Check that an output voltage is approximately 10 V, when
turning the temperature control dial counterclockwise till it stops
("COOL" position).
10. If an output voltage differs from approximately 10 V, the control
panel, wiring harness of fuse is faulty.

A/C Blower Resistor
1. Remove the outer roof.
2. Disconnect the 4P connector (1) for A/C blower resistor (2).
3. Measure the resistance with an ohmmeter across the R1
terminal and E terminal, and across the R2 terminal and E
terminal.
4. If the factory specifications are not indicated, A/C blower
resistor is faulty.
