Check each switch for continuity with the
pocket tester. If the continuity reading is incor-

Never insert the tester probes into the
coupler terminal slots

. Always insert
the probes from the opposite end of the
coupler, taking care not to loosen or dam-
age the leads.

Before checking for continuity, set the pock-
et 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 illustration similar to the one on the left.
The switch positions

are shown in the far
left column and the switch lead colors

are
shown in the top row in the switch illustration.
NOTE:
“

between switch terminals (i.e., a closed circuit
at the respective switch position).
The example illustration on the left shows

There is continuity between red and brown
when the switch is set to “ON”.
