Anyone know about solenoids?

[6SENSE]

Somewhere between revamping my alky setup and moving my alky solenoid from one side of the car to the other it went south . The electrical solenoid itself (part with the wires coming out of it) is seems to be grounding itself. I tested the two leads with a multimeter and its registering 0-1 ohms, not good. before that test I had tried to trigger the solenoid with a jumpbox. Well, just from hooking up the connections the box let out the loud beep sound which lets you know the circuit is grounded.
Maybe it was when I soldered some ring connectors on the leads and got them too hot , I dont know. Is it fried?? I have worked with dump solenoids in the past when I used to install hydraulic setups on lowriders. I recall having an issue every now and then with the solenoids getting magnetized and they would get stuck in one position, usually holding the dump open. Is this a possibility here? I think to solve that issue I would just ground the solenoid itself with a screwdriver or something, but its been so long that Im not sure.
This is a solenoid from Carroll Supercharging that I got maybe 2 months ago. I dont have it in front of me, but I think the company name on it was Peter-Paul ? Anyway, it looks to be a really heavy duty and well built piece. I dissassembled it to clean everything out and there is no issue other than the electrical solenoid itself which cannot be taken apart. I may try to swipe one from a hydraulic dump if I can find one and see if it fits, but thats kind of a last resort.
Thanks for any help. I hope someone has some experience with this.

The coil in a selenoid is essentially a long piece of thin wire wrapped many times. Its resistance value is typically low..remember your measuring a straight wire. Now on some there are two or three wires. If your selenoid has two wires, it shouldnt show any resistance from the coil wires to its physical body. On three wire versions then there will be a wire to its case.

Simple way to test a selenoid is apply 12v across its wires. If you hear it snap..its more than likely good. just touch 12v on it really quick and see if it snaps..if you keep 12v on it for an extended period of time, it may get warm/hot.

Only two conditions can exist..it either does or doesnt. If it doesnt, its bad.

And when I say 12volts.. I mean +12 and a ground

Julio, last night when I put 12v to one wire and ground to the other I did not here a snap. I do remember the solenoid did get warm though, while hooked up in the system normally, being triggered by the hobbs switch (this was during alot of testing). I was listening for it and didnt hear a snap then either, only the faint sound that the hobbs makes.I will try it again, but sounds like its dead. I would think that I should be able to just purchase the electrical solonoid seperately and not the whole assembly

If you knew the manufacturer of the selenoid..yes..contact carrolls to see if they can disclose that.

I hate Hobbs switches...
