Solenoid Help

[Scott Forman]

Still fighting a leveling system solenoid.

The one that I removed is a 3-pin model. The wire that runs to the
small pin is hot (delivering 12v to the solenoid) when the levelers
are "at rest" and the solenoid is open. When a leveling switch is
activated, calling for the motor to run, the wire to the third pole
is grounded (12v goes away) and the solenoid is supposed to close,
completing the circuit and running the motor.

On the original solenoid, I could see grounding of the third pin wire
on my multimeter when a button was pressed, but no voltage came out
the other side to go to the engine. Bad solenoid, I assume.

So today I find an 80amp, continuous, 3-pin, grounded, "normally
open" solenoid at NAPA and install it. Still no-go on the motor. A
check of the multi-meter shows something interesting...the wire that
runs to the third pin shows zero volts "at rest" when connected to
the pin. Disconnect it so it hangs free, and it once again shows
voltage at rest and grounds out when a leveler button is pushed. But
when it is connected to the solenoid, no voltage at any time.

I know the motor will run, because I can jump across the solenoid and
get it to go.

What am I doing wrong? Is "normally open" correct or do I
need "normally closed"? Is a grounded unit correct, or do I need an
insulated one? Any other ideas?

FRUSTRATING!
