64 barracuda fusible link
The more complete set of diagrams:
Voltage is excited electrons, or potential energy.
Current is electrons moving.
Current flow with engine running and the battery recharged would look like this.
If we measured it, the system is roughly at 14 volts when the alternator is working properly.
Lets say the headlight wire insulation got damaged and the car hit a bump such the bare wire touched the metal dash.
That easy path to ground kills the ignition and field.
However as voltage drops below 13 Volts, the path is clear for the battery to take the same opportunity.
If there is a fusible link, that should stop the current flow before too much damage occurs.
