2.16 Electro-hydraulic valve coil test

See the figure 2.9 for the location of the electro-hydraulic valve coil.
This test requires an accurate ohm meter. Disconnect the wiring harness leads at the electro-hydraulic valve coil.
Check resistance of valve coil leads at the terminals. The resistance should be between 8 to 10 ohms. If the values are
not within this range, replace the electro-hydraulic valve coil.
