TEST (LUCAS PUMP)
1. Disconnect wire to solenoid.
2. Remove solenoid noting if plunger is binding in bore.
3. Check coil resistance with ohmmeter. Resistance
should be 9 ohms.
4. Check plunger retraction using a 12 volt source.
Connect positive cable to connector terminal and
negative cable to solenoid body. From the relaxed
position, plunger should retract into the solenoid body
when voltage is applied.
If resistance specification is not met and/or plunger
does not retract, replace solenoid.
