[Amps] B- questions

[Rob Atkinson]

Bill thanks for your answer.  I appreciate the lack of gobbldygook
But I fail to understand why all this metering of B- is somehow safe,
but doing the same thing with B+ is not.  If B- is around minus 3000
v. it seems to me that having only a dinky resistor and/or a diode and
meter between that and the chassis is dangerous.  There must be
something counterintuitive about this I am missing.
