Hi John,
To check the solenoid, remove the armature (plunger) then very briefly apply
power through an ammeter. By doing this the points in the solenoid will
remain closed and full current will flow. (DO NOT leave the power connected
for more than 2 or 3 seconds.)
Then reinstall the armature and check again.
There should be a substantial difference between the two current readings.
When the solenoid is installed the switch from high current to low current
is so fast that you will not see it.

Subject: overdrive solenoid
I installed a new overdrive solenoid and went through the setup per the
manual. I had read from an old overdrive article (club magazine, Norman
Nock)
that upon initial power up, the solenoid should draw about 20 amps, then
drop
to 1.5 to 2 amps. With a direct connection to the battery, I see an initial
1.5 amps, dropping to about 0.9 amps. My battery has been on the charger
and
with a tester it indicates that it is fully charged. It looks like the
solenoid is correctly pulling in with high current and holding at a lower
current, but I just haven't seen anything close to 20 amps. Does this sound
right?
