I just bought new GC extreme valves from grant kustoms, but they wont open.I got ground and I got power(check with test light) but the valves wont open or even click. WTF! someone help me out please.
those valves have 3 prongs, make sure you are only using 2 of them, one power, one ground. if they dont click, make sure they are getting power. if they still dont click, they dont work.
