[Healeys] Auxiliary Electric Power Source

[Bob Spidell]

Assuming your car is still positive ground ('wired as original'), you can 
fabricate a power cable that reverses the hot and ground wires.  If the device 
uses a 'barrel' type power connector--looks like the barrel of a very small 
gun--the outside of the barrel is ground and the inside is hot, hence you'd 
cross over the wires to the connector to get the correct polarity.  Keep in mind 
the outside of the barrel connector will now be hot to your car, so if it 
touches exposed metal you'll let the smoke out (put a plastic vacuum cap over it 
when not in use).

Same story for the more complex connectors like used for cell phones.  Just 
reverse the wires coming out of the cigarette lighter plug.  You'll probably 
need a different cable for different devices, but that's the case anyway.
