This seems like a dumb question but I am trying to figure out how to check voltages on my R911.

The manual (and pinwiki http://www.pinrepair.com/sys3/#fuses) says what the voltages should be at the various fuses. However, since the voltages are AC, I can't connect the other side of the DMM to ground, I should check against the AC neutral side.

However, the power wires go deep into the transformer shielding and I can't get to any bare wires there, I could start cutting the AC wire running in from the wall but there has to be an easy way to check the voltages. Does any system 3 owners know where to put the DMM probes?

You might put black DMM wire ( - ) on white wires number 9 (white grounds wires connector on upper left of transformator)
And the red DMM wire ( + ) on the fuse voltage you want to check.
