CHECKING SWITCH CONTINUITY

Check each switch for continuity with the poc-
ket tester. If the continuity reading is incorrect,
check the wiring connections and if necessary,
replace the switch.
CAUTION:
Never insert the tester probes into the cou-
pler terminal slots. Always insert the probes
from the opposite end of the coupler, taking
care not to loosen or damage the leads.

NOTE:
• Before checking for continuity, set the poc-
ket tester to "0" and to the "Ωx1" range.
• When checking for continuity, switch back
and forth between the switch positions a
few times.
The terminal connections for switches (e.g.,
main switch, engine stop switch) are shown in
an illustration similar to the one on the left.
The switch positions
left column and the switch lead colors k b are
shown in the top row in the switch illustration.
NOTE:
"k—k" indicates a continuity of electricity
between switch terminals (i.e., a closed circuit
at the respective switch position).
The example illustration on the left shows
that:
There is continuity between black and
black/white when the switch is set to "ON".
There is continuity between red and brown
when the switch is set to "ON".
