The voltage for this is 12 volts
The alternator/generator should be producing 13.5 to 14.5 volts

How do you measure the voltage on a car alternator?
get a multi meter that reads dc voltage & touch the black (negative -) wire to the negative battery post & the red (positive +) wire to the positive battery post with car running. car off is battery voltage, car on is alternator voltage.
Why is the car battery charging at 14 volts running and 13.5 not running?
your alternator charges the battery while the car is running. The alternator actually puts out a higher voltage than 14 volts while it is running, but it is reduced by a voltage regulator (most of which are already built into the alternator housing), to prevent damage and premature death of the vehicles battery. While your car is not running, the alternator is not charging the battery, and the 13.5 volt reading you get is just the measurement of the voltage the battery is holding at that given point.
What should the voltage be on a car battery not running?
around 12.5 to 12.8 volts
Your alt light is on but battery is charging?
Does alt. light stay on after car is shut off? If so could be voltage regulator is defective and overcharging battery when running Does light stay on after car is shut off? If so could be a bad voltage regulator--if so may be overcharging battery Check voltage readings at battery should be around 14.2 with car running -- if much higher than this voltage regulator is bad.
Can a car's alternator charge the battery while the car is not running?
No. The alternator has to be turning to produce the charging voltage. It only turns when the engine is running.
What should the voltage be checking battery with car running?
13.5 to 15.5 volts with the engine idling.
Does running a AC in a car affects battery life?
No, because after the car is started, even in traffic, your alternator is putting out the voltage, and that voltage is controlled by the voltage regulator. What Will be affected is your gas mileage/.
What is the correct voltage for a car battery?
For a standard "12 volt" battery, the voltage should be 12.6 to 12.8 while car is off, 13-14 while running. Some newer cars (e.g. recent model Hondas) have higher voltage batteries.
Would a car stall if the battery was dead?
The problem is probably the alternator. If the alternator fails to keep the battery charged the battery will keep the car running until it can no longer supply voltage to essential systems and the car will stall.
Will your car stop running if your battery is low?
Will a Car Stop Running If the Battery is LowThe answer is yes and no. It depends on HOW low. The electrical computer(s) and ignition systems require a minimum voltage. What that voltage number is I don't know, and it probably varies with various models of vehicles and the amount of accessories on it.
What voltage is a Honda Civic battery?
Any modern day car's ideal battery voltage is 13.8Volt. In practive however the voltage you'll find on a charged battery when testing will be in the region of 12.5V to 13V A fully charged battery will read 12.6 volts with the engine not running. With the engine running at idle speed it will read from 13.5 to 15.5 volts.
Max voltage on car battery?
I'm not a mechanic / technician but I believe with the engine running it is a maximum of 14.5 volts
