Troubleshooting
Interchange the Components
The system includes a number of multiple parts:
• Nozzle Valves
• Extension Harnesses
• VCMs
When troubleshooting failed components, it can be helpful to replace the failed part with a working
part at another location. If the problem follows the failed part to the new location, repair or replace the
failed part.
When troubleshooting a failed VCM, a location setup procedure is necessary to show the VCM in the
correct location.
If the problem does not follow the failed part, then the problem is likely elsewhere in the system, and
other troubleshooting means may be followed.
Note: Use caution when failed parts are interchanged with a part that is operating correctly; in rare
cases, the failed component may cause other components to fail at the new location.
Coil Assembly Test
Use a voltmeter to measure the ohms of resistance across pins A and B on the coil connector.
Notice: Correct resistance is:
• 7-watt coils resistance—21 ohms to 23.5 ohms
• 12-watt coils resistance—10 ohms to 11.5 ohms
If correct resistance is not found:
• Clean the connector terminals and retest
• Replace the coil assembly
Coil assembly failures are often the result of two factors:
• Extended valve use with a plugged nozzle
• Extended use in corrosive environments
Recommendation: Clean any plugged valve assemblies immediately.
Recommendation: Rinse the inside of the booms, and wash the outside of the coil assemblies with
clean water as often as practical.
