SPEEDOMETER PERFORMANCE CHECK

GENERAL
See Figure 7-66. 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

The SPEEDOMETER TESTER (Part No. HD-41354) cannot

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.
