Hi Sam,
It sounds to me as though the "hold" coil of that solenoid has failed. (not
a very common thing). What is happening is that the "pull" coil is pulling
the plunger in which opens a set of points to disconnect the "pull" coil.
The result is that the plunger bounces back out, the points close again and
the process repeats itself.
Probably the best thing is to get a new one unless you are very good an
winding coils.

Subject: OD Solenoid
I need a little more help. In testing an unmounted solenoid, I have
read somewhere that by connecting a clip lead to the solenoid wire and
touching it to the positive terminal of a 12 volt battery and grounding
the case to the negative terminal, that it will pull the plunger into the
case. This is suppose to indicate that the solenoid does not have a
internal short. When I did this with my solenoid, the plunger went in
and out / in and out in a very rapid movement. Sounded like a machine
gun firing and there were no sparks that I could see. Can someone tell me
what's going on with my solenoid.
Thanks
Sam Austin
