Different Solenoids

[Hydros]

Here are three different solenoids.

The first and largest is signaled 24 VDC which controls 60 VDC at 1000 AMPS.

The second is a 24VDC, control 24 VDC I'll post the amp ratings later.

The last appears to be a common 12 VDC solenoid you might find on small farm/yard engines.

Of interest in the larger unit, weight is 7.5 pounds with six silver contacts.
The way it works is that it's made to connect 60 VDC and the power to switch it is only 24VDC.  

There is also a position switch, for a light or maybe some other signal that the solenoid is engaged.

These units I'd like to test out for hopping.

Testing, it had large sparks coming from all 6 contacts. Thought is was unsafe to use at the time.
