CHECKING THE SWITCH CONTINUITY

Check each switch for continuity with the tester. If the con-
tinuity reading is incorrect, check the wiring connections
and if necessary, replace the switch.
NOTICE
Never insert the tester probes into the coupler termi-
nal slots. Always insert the probes from the opposite
end of the coupler, taking care not to loosen or dam-
age the leads.
