low oil level, bad supply wire, bad ground wire,
or bad o-rings around the nose of the solenoid
could be all that's wrong with it Huw!
It's a pain, and you'll need a thin wrench to get on the collar
nut, but pull that puppy out, apply 12V across the two
terminals and see if it engages. If not,try soaking it in a bit
of kerosene to clean out the piston/plunger end, and replace
the o-rings it if starts operating. The j-type solenoid should
be pulling around 1-2 amps to hold it in. So that means the
coil is in the range of 6 to 14 ohms.
14V/2 amps = 7 ohms 14V/1amp = 14 ohms
12/2 amps = 6 ohms 12V/1amp = 12 ohms
If it's a lot less than that...the coil may be shorted, but
I personally think that's unlikely. I'll lay odds its the o-rings
are not sealing, or the piston is sticky.
