I have purchased a CA SCAR-Light, and it so happens that I am having a major issue with the wires. I got it upgraded with the power upgrade, from AEX, and the fuse removed when that happened. Now when I plug a battery in and go to fire, the motor runs for one pull of the trigger and then it does nothing. I am not sure what I can do to fix this problem or even why. I have tried numerous batteries and when I went to get it looked at the first time it worked at the shop andnow it doesn't work at all.
