Tippmann A-5 when cocked wont stop shotin

I just bought the old tippmann A-5 egrip of a friend for 25$ and put a new magnetic trigger in it and when I cock the gun it just keeps fireing and wont stop untill i pull back the cocking mecanisem again any ideas why?

thanks

 

out of air..?

Does it do the same thing with the normal trigger? Maybe the drive spring for the bolt is too weak, so the valve doesn't release enough gas to whack the bolt back to the cocked position. New springs are pretty cheap I believe, or you could try taking it apart and giving the bolt a good cleaning/polishing and oiling, so it'll hit the valve faster.

the sear isn't catching.  Check the sear for damage and make sure your marker is properly lubed.  

You can't link to your hard drive. The pics need to be hosted on the internet for us to see them. Somewhere like photobucket.com, then copy and paste the URL (http://blahblah.com/blah.jpg) into the image poster thing.

ya there is, your just misunderstanding the concepts. the e-grip is an electronic sear tripper. which means that your basically telling a microchip when to set off the piston thingy that hits the sear and causes it to trip. its really doing the same thing as the mechanical marker just more complicated and faster. the magnetic trigger only has to do with the pull and release action of the actual trigger. its simpler than you probably think. but ya check the sear.
