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.
How far should the voltage on a car battery drop when cranking the car?
when cranking the engine the battery voltage should not fall below 9.6volts if so replace battery
Can you jump start a Honda ATV from car battery?
Yes, if your car battery is the same voltage as the ATV battery.
Is a car battery a voltage source?
yes
Does a car battery have smaller or larger voltage than a flashlight battery has?
Larger.
What is the proper voltage for a car battery?
12-14v
What is the surface voltage of a car battery?
12.6 volts
Can over voltage kill a car battery?
Yes
Can a car battery over charge it self in the car?
Sure, if the alternator voltage regulator is defective it can overcharge the battery.
Can you describe how batteries are sources of voltage?
The number of cells in a battery determine the battery's voltage. Different types of batteries have different cell voltages. The cell voltage is dependant on the reactive metals used. A typical car battery will have six cells. Because a typical cell voltage has a source voltage of approximately 2.0 volts, this makes a car battery produce a voltage of 12 volts.
Is a 12v car battery the same as a 12v lantern battery?
Voltage is the same but amp hour capacity of the car battery is much higher.
Do car stereos work on any car?
Yes, IF the operating voltage of the stereo is the same as the battery output voltage of the vehicle.
