In order to insure 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 378969 or
379110 Indicator Switch.
NOTE:
Make sure 378969 and
379110 Indicator Switches, in the
P.T.O. shifter or housing, are torqued
to 10-15 ft. lbs. (1.38-2.07 kg
meters).
2. With the other probe, make
contact with the shifter cover
or housing (see Figs. #1 & 2).
3. Actuate shifting device and
the meter or light* should be
actuated when P.T.O. gear is
engaged (see Figs. #3 & 4).
4. Shift unit out of gear and the
meter or light* should return to
normal as shown (see Figs.
#1 and 2).
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 328751X can be used (see
Figs. #2 & 4). A six volt battery is all
that is necessary for a power
source.
