The old solenoid now is in working order. Got it soldered and used super glue on the exposed wiring for protection. But I'm still having small problems with the gun that I am working out with Reaper. Thanks, everyone!
If the old solenoid dies out on me, the new one will be going to a good cause for sure. I may even swap it out just to be safe. Thanks a ton, Reaper and WildWayz.
Definitely makes Vanguard a good company.
