What would cause low voltage in a car?
Three conditions contribute to low voltage on a car battery and they include; old age, poor battery terminal connection, and lastly an undercharged alternator. Low voltage on a car means that a car’s alternator is not keeping enough voltage out which may provide enough current to power the battery.
What causes voltage drop in car?
“Voltage dropping” a circuit tells you when the circuit is too restricted to operate a component (e.g., motor, relay, light bulb) or operate it correctly. If the circuit is restricted, repair it and retest. If there is no restriction and the component still does not run or run correctly, then replace the component.
