(51620 mi) Short Circuit Investigation...

Day One:
I disconnected all the devices off the 30 amp fuse which include the headlights, map light, and stop lights.  No change in the car's behavior. Ammeter flickers, and car won't start.


Day Two:
Nothing works.  No flicker in ammeter.  Nothing.  Battery tests fine.  Full charge. 
 Jumped the car to turn it over, and it behaved normally.  Mystery!
Tested main line entering interior.  No reaction.  No electricity apparently flowing through wire.  Unwrapped the wire from an interior loop, and it worked!  Was it an interior short in the wire?  Maybe in this instance when no power was reaching any part of the car.

Day Three:
It's possible that I mis-wired the system.  It looks as though the I ran the power through the fuse before the ammeter, but the fuse should never have been involved.  There is not absolute certainty.  Many wires are still exposed for continued examination.  Tomorrow's run to Disneyland will be a good test.

Day Four:
It is confirmed.  The power to the ignition was being run through the 30 amp circuit breaker, which was a mistake that resulted in weird behavior by the car.  Live and learn!
