I just got this Funhouse in pretty good shape, needs cleaning but before I tear it apart I want to make sure its all working, and everytime I hit it into the areas that drop the ball into the under playfield tunnel it wont pop back out. Im guessing I need to replace the solinoids the switchers sound like they are working I hear them clicking. Any suggestions would be great...
 
Coil should Ohm out at .4 - .6. If not replace the coil and most likely the associated transistor on the driver board.

If the coil checks out ok then go into the Op menu/solenoid test and see if that solenoid will fire.
Next, ensure the subway switch has a diode on it and the diode is good and ensure both wires are attached to it.
Also - you can simply test a switch by putting your DMM on Ohms and click it on and off and you should read ZERO when open and when closed it should always hand around the same number. If it fluctuates the switch is bad.
