Elkhart Brass SIDEWINDER 8494 WATER VALVE - Manual (Page 6)

12. Perform the following tests with power to both Monitor and Valve Control Modules
and Volt Meter still attached to motor power leads as described in step 4.
 If you have a Joystick squeeze and hold trigger or place the water valve switch to
the ON position. If you have a switch box control place the water valve switch in the
ON position. Within the 12 second window pass the magnet on the gear segment
within 1/8” from the open sensor on the gear case cover assembly (see Fig. 2), the
motor power should cease when the magnet is detected.
 If you have a Joystick; release the trigger (or place the water valve switch in the
JOYSTICK position). If you have a switch box control; place the water valve switch
in the OFF position. Within the 12 second window, pass the magnet mounted on
the gear segment within 1/8” from the closed sensor on the gear case cover
assembly (see Fig. 2), the motor power should cease when the magnet is detected.
Note: If test is not completed within the twelve second window, cycle trigger or
water valve switch and repeat test. Be sure motor power is stopped due to the
presence of the magnet to the sensor and not because the 12 second time limit has
expired.
 Passed; If testing is successful move on to step 13.
 Failed; If testing is not successful for both sensors replace the valve position
sensor components. The same parts are used for both the 12v & 24v systems.
See Figure 2 to determine which style you have. Disconnect valve module power
until valve is repaired.
o For Old Style cover assembly replace Sensor & Harness assembly p/n
36782000 & cover gasket p/n 33048000. Use pipe thread sealant on the
strain relief threads and 242 (blue) Loctite on the fasteners.
o For the New Style cover assembly replace these parts. Sensor Harness p/n
36809000, o-ring p/n 57295000, & circuit board p/n 81264000. Use 242
(blue) Loctite on the fasteners.
