What happens if a car battery is left running?
Other Possible Damage The surge of electrical current can blow the fusible link or fuse element that protects the vehicle’s main electrical system. If the engine of the vehicle with the charged battery is left running, the electrical surge can damage this vehicle’s alternator.
What happens when you disconnect the battery on a car?
The best way to do this would be with a scanner, but if you don’t have one, disconnecting the battery will do the trick on many vehicles. However, disconnecting the battery will not only erase diagnostic trouble codes but also erase drivability, security and radio codes in many vehicles.

What happens when the battery is out of the circuit?
When the battery is out of the circuit, the AC ripple is a lot higher; the voltage regulator has a harder job holding the voltage at the correct point; and any voltage spikes generated by switching solenoids or running electric motors will ride on top of the steady state voltage.
