I have a Stargate machine with the following issues :

1) The 'Left Return Rollover' switch isn't working. It is a "smart switch". Is there a way of testing it?

2) The 'Left Kicking Rubber' next to the left flipper isn't working. The coil activates in 'test' mode and it has the correct voltage when checked with a multi meter, but the contact switches aren't activating the coil during gameplay. The right kicker works fine.

3) When the machine is in 'test' mode, the right flipper doesn't work (It is used to changes values and settings in 'test' mode).
The right flipper does not flip when the button is pressed in 'test' mode. The left flipper when in 'test' mode does flip when it is used to move through the different functions and it performs all of its functions. The right flippers (upper and lower) both work well on the button when the machine is used in gameplay.

4) The glider activates and pivots left and right when the pyramid lifts up, but it does not come forward out from under the pyramid. The 'forward' and 'left, right' functions work when in 'test' mode.

Does anyone have solutions to these problems?

Thanks for the input. I'll start tracing through the matrix and report back what I find.
