My thoughts on this "spark" thing. It is more clear to me to simply unplug one of the battery terminals and run a test light between the bat post and the disconnected cable end. If everything is off the light will be off. If you have a short or something is on the light will light indicating current. Simply start pulling fuses to look for a short in a system. You can set the light so you can see it between the hood and cowl of your Imperial. (Make sure the door is closed or you disable the interior light circuit, because it will light the test lamp, with the door open. I for one could never see that little spark at the cable. Do what works best for you. On the older cars, if you pull the Battery cable on a running car and it is idling correctly, it should stay running. If not you may need a regulator or a alternator/ generator. I would not do this on the newer computer cars because it may cause a voltage spike and damage things. (computer, regulator and such.) After thought.... if you are looking for something that is left on or on by accident, the light will light till you pull that systems fuse. Several times I found out that a glove box light was my battery drain! Good luck!

I remember reading somewhere
if you un hook the battery cable while the car is running and it dies
emediatley something is no good. Is it the generator or regulator?

I'm surprised to hear your 56 has an alternator, but I guess that doesn't
change the answer to your question.
Take the following steps immediately:!!
Turn off everything in the car, and close the doors. Disconnect one battery
cable (it doesnt' matter which one), then touch it to the battery post it
came off to see if any spark occurs. If there is no spark, you're short
has gone away. With the battery disconnected, tap on the face of the
ammeter. It may be stuck from having been driven totally off scale.
Tapping may bring it back to center. If not, you may have to replace it,
but since you don't have a spark when you tap the cable on the post, you
don't have a short, and you can safely drive the car that way - your ammeter
is simply stuck and therefore its reading can be ignore.
IF< on the other hand, you do see a spark when you tap the cable (if your
clock works, one spark on the first tap is OK, but that should not recurr
for a few minutes when the clock needs to wind again), the spark indicates
something is drawing current, and you should leave the battery disconnected
until you find the short - leaving it connected will at the least ruin the
battery, and at the worst, ruin your whole day by burning up the car and
whatever building it is parked in.

To whom mite know whats happening. I put my kick board back in place on the
drivers side of my 56 imperial. There was a heavy gauge wire that grounded
to the frame for a short while. I noticed the ammeter went way off of the
discharge side of glass. I then looked in the engine compartment to see
smoke coming out of the alternator. I moved the wire from where it was
grounded and the ammeter stays on the disscharge side even when I rev the
engine. Have I fried something?
Thanks
