5. Apply hydraulic pressure to the --8 hose port 3L (front side of manifold).
6. Observe fluid flowing from port 3L (bottom of manifold).
7. Remove the --8, 37
_
flare nut cap on port 3L (front side of manifold).
8. Connect a --8, 37
_
flare fitting hose to port 3L (front side of manifold).
9. Connect a 28 VDC power supply to valve V16.
10. Remove the --8, 37
_
flare nut cap on port 3L (bottom of manifold).
11. Apply hydraulic pressure to the --8 hose port 3L (front side of manifold).
12. Observe fluid flowing from port 3L (bottom of manifold).
13. Energize the power supply and fluid flow should stop from port 3L (bottom of manifold).
14. Read and record the T1 voltage.
15. Turn the power supply off and remove the hydraulic input pressure from the --8 hose connected
to port 3L (front side of manifold). There should not be any hydraulic pressure applied to the
manifold.
16. Remove the power supply cable from valve V16.
