Revenge From Mars. Mars defeated!

Video showing the Bally Revenge from Mars machine after many repairs ,a shopout and Mods installed. The camera batteries died almost exactly as I signed off! I noticed in the video that a Martian target (Center left upper playfield.)stopped activating so I inspected it and found that the balls during play had closed the switch blades which wouldnt allow them to register a hit. A quick adjustment and it is back in service.
