Do bad spark plugs cause a battery to go down?
No, that will have no effect on the battery.
What happens if you use a larger car battery then recommended?
If the battery will physically fit there is no problem using a higher capacity battery. Of course the voltage remains 12 Volts but there will a higher amperage available for a longer time should it be needed. This could actually be an advantage if there is ever difficulty starting, there will be more starter cranking time before the battery runs down. Think of it as having a larger gas tank, the gas is the same but there is more if needed.
Jump the car or get a new battery?
If the battery is defective get a new battery. If you just left something on and ran it down, charge the battery and keep going.
If my car won't start and the lights are not coming on but it can be jumped off what may be my problem?
The battery is dieing down and you should go and get a new battery or get your battery charged
Starter is clicking while turning engine over slowly?
If it's turning over slowly but eventually starts, there is more than likely a problem with the battery. It may be drained down or discharged. You can perform a battery test on it to ensure that there is sufficient voltage and Cold Cranking Amps (CCA) to start the vehicle. It also would be good measure to perform a charging system test to be sure that the alternator is charging enough. If it was a fairly new battery, you may have to do a parasitic draw test to be sure that something isn't sucking juice out of the battery when it shouldn't be. Hope this helps.
Why does a battery gauge moves up and down while the engine is running?
A battery gauge "moves up and down" while running because of fluctuations in the voltage output of the circuit which it is connected to. This may be because of equipment on the circuit.
Why the battery gauge moves up and down while running?
Can be loose connections or the alternator is failing.
We have a gauge on our race car that requires 12 volts of power.Our cars battery is a 16 volt battery. Do we need to step down the voltage going to the gauge so it does not burn out?
Are you SURE your car is 16 volt?? I've seen 6 volt systems and 99.9% of the cars are 12 volt. So double check you numbers. I have NEVER seen a 16V battery in a car.
What would cause the voltage gauge to keep flickering up and down?
Either a bad ground to the guage itself or a bad voltage regulator in the alternator. While the enigine is running check the voltage at the battery it should be around 13.5volts if it constantly fluctuates then the voltage regulator is probably bad. Replace the alternator. Otherwise make sure your grounds are good.
What happens to voltage as it moves through a circuit?
Voltage breaks down and looses voltage but not power.The above answer is incorrect. In fact, the question is incorrect because voltage doesn't 'move through a circuit'.
Is there a way to lower down the voltage output of a battery charger?
A: Simply by adding a series resistor from the battery charger. WHAT VALUE? find the current required and use it to IR drop the voltage
What causes low voltage to the car starter?
A run down or nearing end of life battery. Dirty and/or loose battery connections.
When do the anodes and cathodes affect the voltage of a battery?
The anodes and cathodes affect the voltage of the battery all the time. Without them, the battery would not work. The anode provides the positive charge or current. The cathode provides the negative charge or electrons. Part of the anode is down in the battery and part serves as a terminal. Part of the cathode is down in the battery and part serves a a terminal.
Why would the battery light stay on after the ignition is turned off on a 1986 Nissan pickup?
The voltage reg is sticking and will run down the battery.
Will a voltage regulator make the motor shut down on a 2000 roadking?
no it will only make the battery not charge
Why does your amp gauge go down when you turn on your lights?
The amperage gauge will go down when you turn on your lights, because there is a sudden draw of electric power from the battery. The alternator should equal out the power surge.
Please explain the charging circuit in automobile. 1. How does the charging light comes on when ignition switch is turned on 2. How charging light comes on when alternator is not or less charging?
When the ignition is turned on, battery voltage passes down the wire to the alternator to 'excite' the alternator when the engine starts. When the engine starts and the alternator generates a voltage, the light is extinguised by the charging voltage cancelling out the battery voltage coming down the wire. If and when the alternator completetly fails the the light will come back on as there is no sancelling voltage. if the alternator produces a voltage lower than the voltage from the ignition switch then the battery light will glow.
