I picked up an I500 and all 3 of the flippers are working, but very weak (can't make it up the ramp). The fliptronics boards and coils had already been swapped. Measured TP6 and got 75.4 VDC. As I understand it, game was working fine and then one day all three went weak. I haven't rebuilt the flippers yet, but it would seem weird for all 3 to go bad at once. Thinking it's got to be a power issue.
Thoughts?
Thanks,
Jeff
