Ok. I bought off e-bay another valve assembly. It looks brand new, never installed. Coil 3.4 ohms.
I got also a PWM generator. 0-30 V and 0- 30 mA.
I hooked the PWM generator to the solenoid and I couldn't hear or see a thing.
Looks like my cheap voltmeter can show the voltage if it is there. At lower frequencies, due to poor refresh rate it can not show the voltage, but higher frequencies, no problem.
Oscilloscope did not arrive yet.
Will install the new valve soon to see any difference.
Maybe 30 mA are not enough to move the spool inside coil?
