Today, after reading that hydraulic fluid will not spew out when removing it, I decided to take the solenoid out to inspect/test on the bench.. I could fit a 1" crowfoot flarenut 12 point socket on it, but was afraid I would break the socket, so I carefully removed the connector head and verified that a 6pt 1" socket fit best, 25mm would not fit... not wanting to grind a hole in the side of this particular socket for the wires, I snipped the wires fairly short and used a breaker bar to remove the sensor.. I cleaned it up and it is very hard to read, even with using camera phone on zoom, but looks like W 1612 60955 4407 (I assume the 4407 is the date code since this was mfrd 12/07. I used a couple butt-crimps to reattached the wires and tested on the battery... sure enough, no solenoid action, and smoke after a few seconds... I found a "Husco 60955-1 12v" one that looks identical on eBay for $170 with offer, and they accepted $100..." we will see what happens.
