Anyway, the plunger thing is going to be a tomorrow problem.
I noticed two things upon disassembly. This thing looks brand new inside. I have never ever in my life saw such healthy looking o-rings. Second, there's a lot more electronics than I anticipated.
I took the magnet off one of the solenoids and tried to make it toggle. It seems to be very very weak and sometime it doesn't even move. In such a case the current draw stays high which I don't really understand. The shaft seems to be moving reasonably freely.
Here's a video I made. I'm turning the psu on and off like 3 or 4 times. You can see it slightly move at 2 sec, until for the last cycle it actuates properly.
Ideas?
