The voltage drop method needs some research as it dosent
behave quite like Roger states...

Imagine feeding glowplugs as per normal fed along a bus bar
from #4 through #3, #2, and finally #1.
Measuring from #2 to #1 gives a voltage drop say XmV looking
from between#3 and #2 would give a voltage drop of XmV as
well even if we snapped off #2 as the bus bar has a
nominally equal voltage drop along its length (ie) so many
ohms per metre.
So does the voltage drop increase from its 2  lots of 'X'mV
which would show up with a measurement between #3 and #1
with #2 open circuit or what?????
