Test for recognizing the trouble on FET (Field effect transistor) in Controller
(1) Set Digital tester (1R402) in the diode mode ( mark on the tester: Refer to
Fig. D-5.
)
(2) Switch, Terminal, Controller and Stator are connected each other as drawn in
Fig. D-6
.
Do the following steps.
Test 1: Attach Black tester bar to the terminal of white lead wire end on B1 terminal of Switch. (
Fig. D-7
.)
Attach Red tester bar to one of UVW terminal connected with Red, White, Blue lead wires. (
Fig. D-8
)
Check the figure in the tester.
Test 2: Attach Red tester bar to minus terminal of Terminal (connected with black lead wire). (
Fig. D-9
)
Attach Black tester bar to one of UVW terminal connected with Red, White, Blue lead wires. (
Fig. D-10
)
There is no fault on FET of Controller if the tester indicates within
0.39V - 0.41V
in both Test 1 and Test 2.
If either Test 1 or Test 2 results in the improper figure,
Controller is broken
