Default Dead commodore 4040 disc drive

Hi all
Following on from my commodore pet computer I would like to get the 4040 disc drive working as well.
I found a recent post on here for the same drive and as in that one I found no voltage at CR7/8/9 on the main board but unlike the previous post the wiring looks fine although onthe bottom of the transformer there is the earth neutral and live going in but there is a red snipped off wire next to them but is this for 110v?.
The fuse and switch test fine I would like to test for voltages coming out of the power supply to the motherboard but dont know what each wire is.
Any help as always is much appreciated.
Many Thanks
