Continuity Check

Continuity Check
Indicator Switches
In order to ensure that the switch is functioning properly, the
following procedure can be used with the unit on a bench,
or installed.
1. Use a continuity checker, battery type, either meter or
light. Attach one (1) probe to the screw on the Indicator
Switch.
NOTE: Make sure Indicator Switches in the PTO shifter or
housing are torqued to 10-15 (1.38-2.07 kg meters).
2. With the other probe, make contact with the shifter
cover or housing (Fig. 23).
3. Actuate shifting device and the meter or light* should
be actuated when PTO gear is engaged (Fig. 24).
4. Shift unit out of gear and the meter or light* should
return to normal as shown.
This test procedure can be used to check Chelsea wire,
lever, and air shifter covers, although an air source would
be necessary for the latter.
* If a meter is not available the light in the 328751-1X can
be used. A six volt battery is all that is necessary for a
power source.
CAUTION: Indicator switches are capable of 0.5 amps maximum.
