SPEEDOMETER PERFORMANCE CHECK
GENERAL
See
Figure 7-64.
Use the SPEEDOMETER TESTER (Part
No. HD-41354) for speedometer diagnostics. These diagnos-
tics may include:
●
Checking speedometer operation.
●

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.

Use the following procedures in conjunction with the
manual supplied with the speedometer tester.
●
Test results may be inaccurate if tester battery is low.
