Reassemble gear case with the gear segment oriented correctly (see figure 1)

and the stainless steel thrust washer on top of the gear segment. Use a new gasket
or o-ring to seal the gear case cover and secure cover screws with 242 loctite. Lastly
reconnect all harnesses. Test the system for correct operation. If valve opens and
closes as it should perform a final test of position sensor function. With valve closed
disconnect motor power connection J14 & P14. Connect Meter leads to contacts in
P14 as described in step 2. Squeeze the trigger or place the water valve switch in the
ON position, the meter should detect (-) negative voltage then release trigger or place
switch in close position and meter should not detect any voltage. This confirms the
closed sensor is activated and preventing module output voltage for the closed
direction but allowing it for the open direction. Move the valve to the open position
and Squeeze the trigger or place water valve switch in the ON position, the meter
should not detect any voltage, then release the trigger or place the water valve switch
in the close position and the meter should detect (-) negative voltage . This confirms
the open sensor is activated and preventing module output voltage in the open
direction while allowing it in the closed direction. Once completed reconnect motor
power connection.

Summary;

We have tried to cover the most likely problems that can occur with the 8494 electric
Sidewinder’s water valve system. The valve control module is the heart of the system.
Power and ground are fed into the module. Wires for each function (open & close)
come from the control side of the module and carry signal voltage. When one of the
function wires is switched to the common ground from the control side of the module
motor power for that function is sent out from the valve side of the module to the valve
motor in the polarity needed to perform that function. This troubleshooting guide is
going to help diagnose whether the problem is on the monitor side of the control
module, the controller side of the module, or with the module itself.
