Hey Jake, I put power to it and it clicks, is the tip suppose to move or does it work internally inside the solenoid Mike
If it clicked then its most likely working. Check the wires that go to it from the truck's harness. Make sure it is getting power by using a test light on the corresponding + and - terminals. I just pulled mine out and cut the tip off using some d**es and pulled the little brass rod out.
I think you could just put a little short bolt in there though it looked to be a fine threaded 8mm
