SPEEDOMETER PERFORMANCE CHECK 7.27
GENERAL
See Figure 7-85. Use the SPEEDOMETER TESTER (Part
No. HD-41354) for speedometer diagnostics. These diagnos-
tics may include:
●
Checking speedometer operation.
●
Testing speedometer needle sweeping action.
The tester generates a simulated speedometer sensor signal.
This signal aids in determining whether speedometer
replacement is necessary. It can also be used to simulate
running engine conditions for ignition system troubleshooting.
NOTES
●
Use the following procedures in conjunction with the
manual supplied with the speedometer tester.
● Test results may be inaccurate if tester battery is low.
TESTING
NOTE
The SPEEDOMETER TESTER (Part No. HD-41354) cannot
be used to verify the calibration of a speedometer and it will
not verify the speedometer’s function to support legal pro-
ceedings. It’s purpose is to verify speedometer function when
performing service diagnosis or repair. It can also assist in
determining if speedometer replacement is necessary.
