I have a Robocop with a replacement rottendog power supply. The GI wiring from the power transformer to the power supply is jacked up and so I am trying to fix it. At the transformer I have yellow and yellow/white. Looking at the diagram at the transformer it says pin 1&2 yellow/white and 3&4 yellow (which is what I have, see picture)

At the power supply connector it’s supposed to be pin 1 yellow, 2&3 yellow/white and pin 4 yellow which is what I pinned my connector to however when turned on not good things happened at the connector (the pins basically tried to arc and snap off the power supply pcb. So before I continue further, can anyway verify their robocop?

looking at the Robocop schematic I see transformer lugs 1 & 2 are Yellow & 3 & 4 are Yellow/White.

on page 33 it shows CN9 as a sectioned rectangle which I believe is wrong.

CN9 on the PCB 1 & 3 are Yellow which go to a 4 pin connector as pins 1 & 2 being Yellow.
CN9 on the PCB 2 & 4 are White which go to the same connector as pins 3 & 4 being White.

on page 43 it shows CN9 (Input) as 1 & 3 the same and 2 & 4 the same, then (Out) CN8 being 4 chains of G.I.

hope the pics help

Thank you for the clarification on this! Am i safe to assume the plug at the transformer (my 2nd picture) is wired correctly with the two yellows going to two yellows, and the yellow/whites going to the white wires? I guess my question is does yellow/white on the after its gone through the cabinet end up going to pins 2/4 on the power supply?

I'd say yes, but you can also check by powering her up and using your multimeter on AC, check you have 2 chains of 6 Volts.

Doing this with the plug apart, before it goes into the power supply, and probing yellow and yellow/white.
