SOLENOID TEST
The most common issue with a solenoid valve is having an open or shorted connection.
- With the solenoid disconnected from the Power relay, use a Volt/Ohm meter to measure the resistance between the two solenoid wires.
- If the resistance is zero Ohms, then the solenoid is shorted and needs to be replaced.
- If the resistance is infinite Ohms, then the solenoid is open and needs to be replaced.
Common values for a Superior solenoid is 550-620 ohms, a Jefferson solenoid is 90-95 ohms. Any values significantly outside these ranges should be suspect.
- Check that the valve diaphragm and spring are in good working condition.
