Neutral Safety Switch (Electrical); Interlock Module; Hour Meter - Simplicity Coronet Series Service & Repair Manual

F. Test Neutral Safety Switch - Electrical
(Gear Models Only)
NOTE: The neutral safety switch threads into the top of
the transmission case and may be more easily tested if
the transmission is removed.
1. Remove the neutral safety switch plug.
NOTE: The plug is connected using small screws and
may be more easily tested if the transmission is
removed.
2. Place the ground speed control lever in neutral.
3. Set the VOM to Ohms. Probe the switch terminals.
The VOM should show continuity.
4. Move the ground speed control lever out of neutral.
5. Probe the switch terminals. The VOM should show
no continuity.
G. Interlock Module
If all other switches, connectors, wires, and cables have
tested OK, the interlock module is at fault and must be
removed and replaced. The module is not testable.
However, if available, a known-good module can be
used to test the system.
1. Unplug and remove the old module (A, Figure 34).
2. Substitute the know-good module for the old module.
3. Turn the ignition switch to START. If the engine turns
over, the old module is bad and must be replaced.
MISCELLANEOUS TESTS
Perform the tests listed under Test Series
"Checking the Power Supply" before performing the fol-
lowing tests.
A. Test Hour Meter (Where Applicable)
The optional hour meter (Figure 32) can be easily tested
by turning the ignition switch to RUN and observing the
meter. The meter should register the passage of time.
