Hi everyone, I am having trouble with this Game I picked up. The
Shooter solenoid won't fire and the magnet that holds the ball in the
roto shooter magnet won't hold the ball. I am getting 46 volts on the
yellow wire that is common for all solenoids, and the same on the
other terminal on everything but these 2 solenoids. Where do I need to
be looking?
Oh, I see that the Transistor at Q7 (The "Fire Missle" or Roto
Shooter) was changed to a TIP 100 will this be an issue? I can put a
TIP 102 in if necessary, but would this be the problem? I also just
noticed that 1 of the caps on the flipper button is disconnected/
broken off at the button. Would this also be an issue?
Thanks for any help, I need to clear my head on this and get it sorted
out.

Ho Lloyd, Q7 should be an SE9302, which I think is compatable with a TIP 102, just not sure on the TIP102 to TIP100 comparison, I think they are OK, but not 100% sure.

On the button, I meant the capacitor lead is broken off the switch tab, for electrical connection. I am just trying to make sure where to solder it back on.

The other side is different... The game has 2 sets of flipper buttons, one set for regular flippers, and one to control the Roto shooter, left side is for reversing the rotor to line up the shot (This is the one with the caps), and the one on the right for firing the ball. The one one the left has a switch similar to a WPC coin door high power lockout switch, as opposed to a regular blade switch for a flipper. I am pretty sure I have the cap part worked out though.

Thanks, Dave

Hmmm, The specs on the transistors show the only differences are the Absolute Maximum Ratings for the Collector Base and Emitter Base Voltages are 60 on the TIP 100 and 100 on the TIP 102. I suspect the 102 is more robust, but the 100 would handle the voltage, correct?
