2. Lock Switch lever complete 

    with an insulating tape or a like.

[4] TROUBLE SHOOTING (cont.)

Test for recognizing the short-circuit of FET* on controller

Fig.  T-3

Remove Battery, and then do as shown in 

Fig. T-3

.

3. Attach the black bar to (+) Terminal,

    and the red bar to (-) Terminal.

    Note

: Be careful not to reverse them.

              The reverse attachment could spoil the test. 

    Wait until the display shows the value without 

    fluctuation.

1. Set Digital tester (1R402) in the diode mode (           mark).

*FET: Field effect transistor 

R

epair

**It includes Controller.

4. There is no fault of FET on Controller if the display

     indicates

 between 0.79V and 0.81V

     If the display indicates 

0V or 0.4V approximately

     FET built in Controller has any trouble, 

     and Stator complete** has to be replaced.
