<VV> short circuit '69 lights technical

[Jim Bannister]

Mike, If I were you I'd make myself a little test light.  Take one of your
blown fuses and solder a wire to each end.  About six feet of wire later,
connect a tail light bulb or similar to the wires.  Now when you plug your
test fuse in, the short circuit will light the test light while the test
light protects everything from excessive current. Now you can start wiggling
wires, connectors, light bulbs etc. until the test light goes out.  When it
goes out, you've found the source of the problem.  
Have you changed any bulbs lately, a bulb installed backwards in the socket
can cause a short like you describe?

 I have a blown fuse on my wife's '69. I replaced it and the new one (20 A)
immediately blew. That is where I stopped today. There are 8 lights on the
outside of the car + the instrument lights. This translates into a LOT of
potential bad wires. No apparent cause-effect.
   
   What I'm looking for is the best logical method of finding the bad wire.
I'd first remove all the light bulbs to be sure it isn't one of them. I've
got the meter to check for continuity etc, but want the most important
starting point. I think the basic method would be to check each + light wire
for continuity to ground.
   
   I hate dc electrical faults!
   
   I wont be able to start for a day or so. I'll wait for answers.
