ok. I bought two gc 450 valves about a year ago. I never got around to putting them on till last night. Well I wired them and everything and the valves do nothing. I got them brand new from a buddy of mine. I tried switching the wires around and still nothing. any Idea's????
be careful when you are takin them apart that you set the o ring in right befor you put it backtogether, or you will have a bag leak, and if you pinch the oring it will prolly stretch.
