Hi Vogavt,
Just one tip - If you are using a mains operated oscilloscope (without an autotransformer or other means of isolation) make sure the earth connection of the probe is only connected to an earth point on your machine. Shorting various unknown points to earth while testing can ultimately spell disaster.
The portable, battery operated, hand held scopes are in may ways a lot safer to use when it comes to trouble shooting as they have a floating GND and the above does not apply.
Tweakie.
