STEP
5.
Check manifold wiring harness and hydraulic valve solenoids for continuity.
a.
Disconnect manifold wiring harness (Figure 3, Item 1) from control box (Figure 3, Item 4).
b.
Check continuity between all wiring harness connector pins (Figure 3, Item 2) at connector
(Figure 3, Item 3). This will also check continuity of the appropriate valve solenoids.
c.
Refer to Table 1 for lead locations.
d.
If continuity is indicated, reconnect manifold wiring harness (Figure 3, Item 1) to control box
(Figure 3, Item 4).
