Sounded like he wanted to place a kill switch inline and I would place the 
switch in the pos.

The reasoning for removing the negative terminal first is the fact that the
metalic tool used for removal could come into contact with the grounded
structure of the car...Not a good thing if you remove the positive terminal
first..The negative should always be the last connection when re-connecting
the battery for the obvious same reason...Of course do the reverse for a
positive ground car...Jim, K7RDX...40+ years in the collision repair
field..I have seen technicians do all sorts of crazy things..

This presents an interesting question. When working under the hood of your
car, it is recommended you disconnect the negative lead to the battery for
safety. Why the negative lead? When you disconnect the positive lead, the
positive connection on the battery is still "hot" to the engine, frame,
body, etc. of the car. An accidental short from the positive terminal to the
car body is still bad news. If the negative terminal is opened, then the
positive terminal of the battery is only "hot" to the negative terminal of
the battery and not the body, frame, etc. I'm not saying this is what Larry
wants to do, just a little food for thought.

where to interrupt power  I am going to put a switch across a 12v auto
battery to interrupt power in case of whatever. Should I break the circuit
between the negative terminal and ground or between the positive terminal
and the load? Larry L. Ravlin AA7LR EX KØAEY &
