How It Works; Testing; Electric Pto Clutch; Purpose - Toro Z580 DFI Z Master Service Manual

How It Works
The hour meter is made up of an electric "winder" and a
mechanical clock movement. When power is applied, a
coil is energized to wind the movement. The movement
unwinds in about 2 seconds. As it finishes its rotation, it
re-energizes the coil so that the cycle can start over (Fig.
541).

Testing

Verify that 12 volts DC is present across the two termi-
nals when the engine is running. If there is no continuity,
replace the hour meter. The meter is a permanently
sealed unit and is not repairable.
