Speedometer
The speedometer can be tested using a DC pulse gen-
erator, or by verifying the gear tooth sensor is operating
properly and operating the machine with the wheels off
the ground.
CAUTION
Make sure the voltage source is turned OFF be-
fore connecting it to the electrical circuit to avoid
electrical shock and prevent damaging the
gauge.
Using Pulse Generator
1. Connect speedometer to the pulse generator and
DC voltage source (Fig. 37).
2. Take test point readings (Fig. 38).
A. Set generator to 325.2 Hertz. Apply signal to cir-
cuit. The needle should point to 4 MPH.
B. Set generator to 650.4 Hertz. Apply signal to cir-
cuit. The needle should point to 8 MPH.
C. Set generator to 975.6 Hertz. Apply signal to cir-
cuit. The needle should point to 12 MPH.
3. Turn off the voltage source. Disconnect voltage
source, gauge, and variable resistance.
Using Traction Speed Sensor
CAUTION
When testing the speedometer using the gear
tooth sensor, make sure all moving wheels are
properly lifted and secured off the ground to pre-
vent the machine from moving and causing per-
sonal injury. All wheels must be off the ground
