[Steve Hawkins]

Then why do you get sparks when you install the ground first or remove it
last?

The only reason for disconnecting the ground first is to avoid any  
shorts to ground while you're fiddling with the positive cable.  
Electrically there is zero difference whichever cable you disconnect  
first.


Mental note to self: steer clear of any MSD ignition...
