Quoted from Skydivewags:3. When the ball hits the bumpers fast, I get dimming of the lights on the board. Is that normal? Do people upgrade the power supply to eliminate that? If so, what do you use?
That is not normal. Here is my list of possibilities:
Low Line voltage. Should be 120v in North America. Make sure the transformer is jumpered properly for your voltage.
Loose or burned worn backbox power connector
Switching to LEDs will eliminate this problem and be better for the game in the long run.
Quoted from Skydivewags:4. I've had a couple times when the machine has been running a long time that the voice stops. No fuses blown, I just shut it off and on, and it's good again. Is it Just a standard heat issue, or should I be careful of a larger problem looming?
Could be dirty speech pot on the S&T cutting out. Try cranking it back and forth a bunch of times to clean it.
