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.
TIP
• Before checking for continuity, set the digital circuit tester
to the “  ” range.
• When checking for continuity, switch back and forth
between the switch positions a few times.
