batteries

[David Ward]

When disconnecting batteries it is always best to disconnect the ground side first. If you happen to hit a ground (frame, body etc.) with the wrench you won't get a spark.

Contrary to popular belief, electrons flow from negative to positive.

Presumably, if you disconnect the positive cable, you get the same result, but if the disconnection (by a switch, for example) isn't complete -- if something is 'tapped' before the switch -- then the disconnection is only partial. If there is a short from a positive wire to the frame, with the negative disconnected, then there is no fire. So the negative is the 'safer' wire to disconnect. (Of course, if there's a short, you'll find it rather quickly after hooking the battery up, again.) This is all reversed in a system with a positive ground.
