Nope, you're correct and my mistake.I was actually going to have him disconnect one coil wire from each coil, but then in haste thought you could do that by disconnecting CN2. When this happens, the fuse(s) will blow immediately.
FUSES FOR BLUEX MACHINE DRIVER
Since the diodes were reversed and power was applied, it shorted out the the driver transistors associated with both flippers. You should hear it click when the game starts.Īt this point, I'm leaning towards bad driver transistors on the flipper board. The RY1 flipper replay could be suspect on the cpu board. What about the flipper coil wires? Did someone cut them at one point and added a connector from the backbox? Is it shorted? I know data east put a 2 pin connector that disconnects 8v flipper up power before it goes to the backbox. Doubt it's an issue, but I would elimate everthing at this point.įollow the flipper coil wires all the way up to the backbox. It should have a lane change/high score switches attached. Robocop's flipper coils didn't use an eos switch, but what about the flipper cab switches? Should be normally open. 6 in one direction and open when you reverse the leads. DMM on diode reading, cut a lead and you should get. PPB board J7-5 feeds 50V to-> CN2 pin 9 - 50VDC flipper powerĬheck J7 pins 1 and 5 for shorts, Check CN2 pin 8-9 for shorts.įlipper coils measured right? So that's good.įlipper diodes are installed right but did you measure them? Did you use new ones? With the game off. PPB board J7-1 feeds 50V to-> CN2 pin 8 - 50VDC flipper power So I'm not sure if that's going to tell you anything because, everything is disable.
Plus, 50V from the PPB board and 8VAC for your hold up flipper voltage. Correct me if I'm wrong but, my understanding is by unplugging CN2 you are disconnecting the wiring to the flipper coils.
