Default Just got myself a commodore pet setup but not working

Hi all
I always wanted a Commodore pet computer and after years of looking I have now got one a Commodore 4032 and a 4040 disc drive only problem is neither are working.
The 4032 makes the chime noise when switched on but nothing onthe screen and the 4040 seems to be completly dead.
working a bit backwards I thought I would look at the disc drive first as it could be an easier fix 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 but dont know what each one is so any help would be brilliant.
