TROUBLESHOOTING THE 8494 SIDEWINDER WATER VALVE

Refer to wiring schematics P/N 98184010 (12v system) or P/N 98184510 (24v system)
for trouble shooting. Refer to the 8494 Electric monitor system layout drawings P/N
98184000 (8494010 12v system) and P/N 98184500 (8494510 24v system) for repair
part reference. These drawings are available for download from our website

First check these items:

 Voltage at the monitor control module and valve control module should be 11-

14 VDC for a 12v system (22-27 VDC for a 24v system) when measured
under load. Make sure polarity is correct and there is a good ground
connection. Chassis grounds are not recommended.

 If this is a repair job or new installation where the gear case position has been

moved from the as received (Standard position 4) position, see Figure 1 to
make sure the gear case parts have been reassembled correctly.

 All testing to be done with power on for both the monitor and valve control

modules.

Problem; Valve will operate in one direction only or not at all.

Checking for faulty position sensor(s).

1.

Disconnect 4-position sensor harness connection (J13 & P13) and try to operate

water valve.

 If it now operates in both directions 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.

 If there is no change move on to step 2.
