Speedometer Off-Vehicle Inspection
Remove the speedometer from the meter assembly and
measure the resistance and the current consumption
between each terminal.

Speedometer Current Consumption
Note: 1. Use the analog type circuit tester.
2. Since the current consumption fluctuates when
the source voltage varies, check to be sure that
the voltage applied is 12V ± 1V.
