Come on everyone... think!
if EITHER side of the battery is disconnected
EVERYTHING electrical is without power!
(no return path to the power source)
( as a reference for from where I speak....
These days I'm an electronics/robotics/software
engineer working on automating the manufacturing and
testing of Passive Fiber Optic Couplers.)
I've spent quite a bit of time pondering this one myself
from an engineering stand point.
In the end, there is only one really good argument for which
one to disconnect. Disconnect the battery terminal wired
to the chassis of your car. (pos. or neg. depending on you
chassis ground scheme)
>From a safety standpoint (the only feasible argument)
you won't have to worry about shorting across the contacts
with a wrench.
I use to always think the pos. side should be disconnected
to stop any wiring from having V+ on it and possibly shorting
to the body work or other wires.
But you don't have to worry about this. With the chassis disconnected
from the battery, where could electricity flow?
So... disconnect the chassis to battery connection.
