Cpclee,
True or False:
1)You measured this with ALL your components unplugged
2)The receptacle (where you measured 122-0-0) was on a different circuit (off a diff breaker) from the outlet that measured 122-4-4.
If 1 and 2 are both true, I have no idea why the 4 volt offset is there.
If 1 is false: In some power supplies there are diodes that are connect the chassis to ground in both directions. The chassis could be completing a strange trip back to earth ground and is causing the offset.
If 1 is true and 2 is false seek immediate shelter (just kidding)
Please let me know as much about what was going on that day
