I am working on a Twilight Zone pinball machine and i am not getting any voltage to the flashers (lights under the domes and under the eye on mini playfield and middle light under the lamp post above mini playfield.
The wiring from they eye and spotlight are black wire with an orange spot every 3 or 4 inches and two solid red wires. The black/orange go to
J125 on driver board (linked to Q38 transistor, which the transistor and all components linked with q38 test good and have continutiy) and i believe the red wires go to J107. I have continuity from the playfield lights to the driver board for all wires mentioned.
according to the schematic i should have 20 volts ac going to the red wires at j107.
Coming out the transformer , if im reading schematics correctly, the power is coming from the two white wires with red stripe. When i test these two wires i get 17 volts ac at the first molex connector right after the transformer.
At j107 i am not getting any voltage, which in turn gives me no flashes. For example I have zero voltage at light socket for the eye on mini playfield.
Any ideas what to look at as to why no voltage is making it to the driver board? I have not yet tested continuity from the whire/red stripe wires from transformer to the two red wires at j107. I will do that tomorrow, but i wanted to throw my question out there now.
Any help/insight will be geeatly appreciated.
