Note in Repairing
(1) Use the full charged battery that has a star mark. (
Fig. T-1
)
(2) Do the running test 10 times.
(3) When Housing is disassembled, check the conditions of the electrical parts
(Connectors, Lead wires, Switches, etc.), Rotor, Stator, Gear section, etc.
[4] TROUBLE SHOOT
Star mark
Fig. T-1
Trouble Shooting using Tester
Trouble on FET (Field effect transistor) of Controller can be checked with Tester as follows. See
Fig. T-2
.
Fig. T-2
1. Set 1R402-A Tester to diode mode.
2. Removing Battery, lock Switch lever
to “ON” position, for example, by bundling
with tape.
4. Controller is
in order
, if the Tester designates
0.7V ~ 0.9V
. However, if
0 V~0.4
V
is designated,
Field effect transistor built in Controller, has any trouble. Then,
the Controller has to be replaced
.
Terminal
3. Contact black probe with (+) Terminal. And red probe with (-) Terminal.
Wait until the Tester designates stable figure.
