For some reason many people have interpreted my caution to use
different trouble shooting technique on circuits with switched ground
as a criticism of DeLorean in general. Never said such. But it *DOES*
require different approach: can't simply put an ice pick light on
questioned device. If device's ground remains hot need to start
tracing ground wires (archives are full of DeLo ground problems --
inevitable on a plastic car, but isn't that what I've maintained all
along?). Also introduces possibility of feedback and crossover from
other circuits.

IMHO does no harm to advise people otherwise familiar with similar
vintage metal bodied American automobiles of DeLo differences.
