Test for recognizing the trouble on FET (Field effect transistor) in Controller
Trouble on Controller can be checked with Tester as follows.
3. Attach Black tester bar to the plus pole,
Red tester bar to minus pole of Terminal.
And, check the figure in the tester.
Note: Be careful not to attach the bars in reverse.
1. Set Digital tester (1R402) in the diode mode
( mark on the tester).
4. There is no fault on FET of Controller
if the tester indicates within 0.79V - 0.81V.
If it indicates 0V or 0.4V approx.,
Controller is broken. Replace it with a new one.
