Quoted from Roamin:Here, I decided to measure all the outputs of the transformer. You should disconnect the 3 output connectors (with the machine turned off) and then turn it on. Measure all the pairs I have color identified and compare the voltages. This way we'll see if the transformer is outputting correctly. The gray , gray/white and grey/green wires are center tap, so you'll read 20 Volts on each side and 40 volts from gray to gray/green
In the other connector , all 3 yellow are the same wire and all 4 yellow/white are the same wire so measurement can be taken from any pair. I would still test them all , leaving one probe on the yellow, then touching all yellow/white, and repeat again with all yellow wires. It should always read around 8v.
The 2 purple wires should measure 110 VAC

LOVE that representation of the connectors! Very easy to see without having to find wire colors! Nice work!
