It's too blinking cold in my garage at the moment, I am thinking of getting it insulated, but to be honest, we are looking to move house so I don't really want to invest too much into and with the summer coming up, I may just have to hold out on it.
I am looking first at the right lower and upper flipper which are causing issues, the symptom being the right flipper will raise slowly if the button is held down, the top flipper doesn't do anything. Currently I am just pondering the schematic first, trying to get it right in my head before overlaying it onto what I can see on the play field.
On the right flipper, I should have the blue wire coming in from the power supply, bridging over the coil via the diode onto another unnamed switch, which appears to always be open, the end of stroke switch then returns to the center tab on the coil. The right side of the lower flipper should also have a blue and grey line to the right flipper button.
I have checked all of this over and apart from bad wiring, which I will completely re-wire. It looks like the wire from the other side of the diodeto unidentifiable open switch actually goes to the end of the bridged side via the diode on the upper flipper. Is that right?
