Can't speak for the new style Shocker, but if you have an older shocker (which I take it you do, as there is no new style "Shocker Sport), it's my understanding that the solenoid actually isn't anything like the Impulse. It's actually a dual solenoid system. I don't actually own one, but with every other solenoid-powered marker I've ever used, as long as the marker is powered (i.e., turned on), there is an audible "click" when you pull the trigger. Like I said though, I've never owned one. I know how you can take the mystery out of it though. I'll break it down.
Step one: Go find your air/nitrogen tank
Step two: Either attach the tank to an ASA and run a hose from the ASA to the marker, or if it's an adjustable tank, run a hose from the tank's output port to the marker.
Step three: Insert battery(ies) into the marker, and turn it on.
Step four: Pull the trigger.
Does the marker fire gas? If so, your solenoid is working. Does it do nothing, or leak significantly? If so, your solenoid is not working.
should have made it more clear at the top.
so are you fireing this without the gas??
Dude, did you read the first post at all?!? It's not really my business, or anything I should probably even comment on, but dear God! He said pretty bluntly that his SOLENOID wasn't clicking, and that he was using a DEGASSED shocker sport. Use yer eyes.
