Data East Back to the Future (Data East, 1990) Switch problem

[clark]

I'm working on my old machine. I've fixed some broken switches and that corrected the mulitball problem but now the ball won't eject out of the chute into the ramp. It knows the ball is in the chute. It was working until i fixed some other switches and drop targets

To find out what switches are not working , unscrew and remove the outhole apron, and remove all the balls. Go into self test, go into switch test, and check all the troft switches, outhole switch, shooter lane switch, and both flipper end of stroke switches. Record all non working switches and tell the results. Go back through all your work and check for connection shorts .
