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.

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 &
