My friends Defender was acting up so I told him to drop it off and I would see if I could fix it for him. You turn the game on and it comes up fine.But none of the controls work,coin mechs wont put a credit on it and the advance buttons on the coin door do nothing.Basically the game wont take any inputs. Sounded like a grounding issue to me. Replaced the plug,you know easy stuff first. Then ran a ground from the braid to the control panel to the widget board to the monitor,still nothing.Now I know the boardset is good as is the widget board because I had friend test it with his setup and it worked fine. I was told to check the voltages as that could cause this.Thats first on the list tonight.I also plan tying in the grounds I ran to the switcher. It does have the Arcadeshop adaptor for using a switching power supply with the origonal cabinet plugs. Any other suggestions would be great.Thanks in advance....Dave
