I went to HRP and made some passes on the bottle for the first time, and everything was working fine. The next day I had the bottle refilled and hooked everything back up. As a test I armed and sprayed for a bit on the highway, so it's definately there, but now my purge button isn't doing anything. Is there just nothing in the lines or is it electrical?

n2O noob here

 

Turn on the bootle and CAREFULLY crack the line open a little bit on the NOS feed line on the purge valve. After a little loosening, you should hear escaping gas and the fitting will chill. The you know you have nitrous to the purge. You can have someone touch the purge solenoid while you press the button - they should be able to feel it open and shut as you push the button.

Where on the purge solenoid am I supposed to feel for it?

maybe a pic or something

 

Where the wires go into the body of the solenoid should do it.

well seeing how you armed it and ran on the highway... and it all worked... you are getting nitrous...
you either have electrical problems to the purge valve or the purge valve is gunked up..
