Quoted from Solenoid_Man:Targets solenoid:
Measured for voltage from ground to both terminals on the solenoid (NO-26-1900). I measured 47 VDC on one terminal and 0 VDC on the other. My understanding is that both terminals should have approximately the same voltage but only one does.
If the solenoid isn't pulling in with 47VDC on one terminal and 0VDC on the other, then it says there is an open circuit on the coil. Carefully inspect the green coil windings that attach to each lug incase one has broken off at the lug.
