I need help with my air cannon. It was working fine when I first built it. After sitting for a year, it stopped working. Today I changed out the solenoid and it worked a couple of times and the then started acting squirrelly. I put the original solenoid back on and it worked again for a bit and stopped again. I put another new one on and now nothing, just it clicking.
I uploaded a video with this so you can see it and hear the solenoid clicking. I'm hoping one of you out there have had this problem before and there's an easy fix for it.
Thanks in advance for your help!
