I have spoken already ready to someone like this but its a bit hard to explain over the internet so I was wondering if anyone else knows how to fix this problem...I had my rotor on the mini full with balls, the bottle with around 2000PSI attached and the ASA recognised but when I came to switch on the mini and try to fire it had a constant red LED apart from when it turned green every two seconds it seems. The mini didn't fire any air or balls, I have looked at the battery and it seems fine, just wondering if anyone else has any ideas what might be the problem. Cheers guys
