During startup the large reset coil on the motor board relay bank resets, but the large reset coil for the relay bank under the play field does not. The colored wires to either large reset coil are the same and if I jump the motor board coil to the playfield coil it will reset as it should. I suspect a broken wire (white-brown-yellow plastic) along the circuit path between the two coils. But is there any other location (besides the jones plug) where the playfield relay bank coil wire might be connected?
Thanks
