Wiring diagrams are on site herepackardinfo.com/xoops/html/modules/article/view.article.php?268.
The sender is grounded via tank mount then has a single wire direct to one side of gauge. That is part of the main body loom going from trunk area to instrument cluster. If memory serves, the wire drops down out of loom and trunk thru a hole in a trough like channel between trunk floor and outside body panel just by the license plate. Other side of gas and temp gauge goes to a voltage regulator which is a small rectangular can located in the bottom center of cluster between two smaller circuit breakers. Hopefully you have the correct sender. It has to have approx 80 ohms at empty and 10 ohms at full. Important the wire is not grounded directly as the gauge can burn out.
When you jump, what exactly do you do? The coil is fed off ignition switch directly. The start switch also is fed from ign switch, thru trans neutral safety switch if you have an Ultramatic then to carb starter switch and then to starter solenoid. Any short would be smoking as there is no protection on that part of circuit. On the duplicate part of your question, JHH brought up a good point. If the voltage is dropping via bad connections or too small a battery cable, the spark may not be adquate
Replacing the loom properly will be expensive but depending on how authentic you want to be, others have used univeral looms. If that is something you want, here is a link to a supplier having one with proper 6v gauge wire.stores.ez2wire.com/StoreFront.bok
