Wire Shift PTO 6 and 8-Bolt PTOs
Indicator Switch Continuity Check
1. Use a continuity checker, battery type, either meter or
light. Attach one (1) probe to the screw on the Indicator
Switch.
2. With the other probe, make contact with the shifter cover
or housing ( Fig. 21 ).
3. Actuate shifting device and the meter or light* should be
actuated when PTO gear is engaged.
4. Shift unit out of gear and the meter or light* should return
to normal as shown.
In order to ensure that the switch is functioning properly, the
following procedure can be used with the unit on a bench, or
installed.
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.
