Check each switch for continuity with the pocket 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 coupler terminal slots "a". 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 pocket tester to "0" and to the "Ω × 1" 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 illustra-
tion similar to the one on the left.
The switch positions "a" are shown in the far left column and the switch lead colors "b" are shown in the
top row in the switch illustration.
NOTE:
" " indicates a continuity of electricity between switch terminals (i.e., a closed circuit at the re-
spective switch position).
The example illustration on the left shows that:
There is continuity between black and black/white when the switch is set to "OFF".
There is continuity between red, brown/blue and brown/red when the switch is set to "ON".
