A short to voltage is when a wire that should not have battery voltage has battery voltage. This would happen if a wire had rubbed through another wire. The other cause would be an electrical component failing and sending voltage down a wire that it shouldn't.
NOTE: Shorts to voltage are very uncommon. I specialize in electrical automotive repair, and I can not even recall one time I have seen a short to voltage.
Car.
what is short to voltage in a car electrical circuit & how to check it ?
You can't
car.
Ohm's Law applies where Voltage = Current x Resistance
A: As soon as a DC voltage is applied the capacitor is a short or no voltage

really short and flat
In Short circuit test High Voltage side is feeded with 2-5% of the High Voltage rating to circulate approximately full load current in low voltage winding by short circuiting it. Low voltage is generally short circuited to facilitate measurements because it is more difficult to measure the quantities at high voltages.
A multimeter is the best tool for the job Set the voltage to 20 V. dc.
A multimeter that covers 0/20V dc will do fine for a 12V car circuit.
Most likely a short circuit will cause no voltage. Due to the high current on a short circuit fault the over current protection of the circuit will trip. This will cut the voltage supply off completely.
