Default Re: Dead commodore 4040 disc drive

Still with the plug unplugged from the mains and the unit's mains switch in the ON position, can you measure the resistance (not continuity) between the following two pairs of points:

One side of the mains switch to the live pin of the mains plug, resistance is?
The other side of the mains switch to the neutral pin of the mains plug, resistance is?
One side of the mains switch to the other side of the mains switch, resistance is?

(If the mains switch has three pins, use the ones which have wires going to them as one side of the switch / the other side of the switch, ignore any third (unconnected) pin.)

From what you have said, can I take it the mains cable plugs into a socket on the unit's rear panel, like the one on a kettle or similar?
