CHECKING OF SWITCHES
*********************************
Checking steps:
●
Turn the switch key to the “ON”, “OFF” and
“LOCK” several times.
●
Set the pocket tester selector to the “
Ω ×
1”.
●
Connect the tester (+) lead to the “R” lead
terminal in the coupler and the (–) lead to the
“Br” lead terminal.
NOTE:
Use thin probes for checking the continuity.
Otherwise, the probes may contact other ter-
minals inside the coupler.
●
Check the continuity between “R” and “Br” at
the switch position “ON”
1
, “OFF”
2
and
“LOCK”
3
.
There must be continuity (the tester indicat-
ing “0”) at the “ON” switch position, and there
must be no continuity (the tester indicating
“
∞
”) at “OFF” or “LOCK”.
There is something wrong between “R” and
“Br” if there is no continuity at the “ON” posi-
tion or if there is some continuity either at the
“OFF” or “LOCK”.
NOTE:
Check the switch for continuity several times.
*********************************
5. Next go on to checking of the continuity
between “B/W” and “B” at the respective
switch position, as in the same manner
mentioned above.
6. If there is something wrong with any one
of the combinations, replace the switch
component.
