I have a Selkhmet gauge on my FX impact mark three, which when I tried to charge it today battery said it was at 20% after leaving it charge for approximately 25 minutes. I went down and looked at it. The battery shows one bar and the gauge is completely stuck. Won’t do anything can’t cancel. It can’t can’t charge it nothing .This is like the second time this gauge has given me a problem. The first time it did something that wouldn’t let it go off of whatever pressure it was on for the price of this gauge I would think it should be much better. I’m half tempted to put the original gauge back on the gun and be done with it. Any ideas as to what could be wrong?
