Car Battery Role & Function
When it comes to the high-level functioning and running of your car, the car battery is by far one of the most important components. The last thing any car owner wants to experience is being left stranded on the road’s side with a dead battery. The battery is the power of your vehicle – without it, you wouldn’t be able to drive anywhere. So why will your car not start after a new battery is installed?
The car battery provides electricity to power the accessories and components within your vehicle. Without the battery power from the car’s internal battery, no electrical component will work, causing your vehicle to run without the lights, the radio, and the power windows.
The battery must transfer the chemical energy into electrical energy to deliver voltage to the starter. In addition, the battery stabilizes the voltage to keep your engine running consistently and constantly. Without the battery, the car would not have the energy required to start and maintain the power to run your vehicle.
When looking at why “my car won’t start after a new battery is installed,” there are certain conditions to look out for as to why your vehicle is not turning over.
Car Won’t Start Causes & Symptoms
Your car might not start for numerous reasons and boil down to various root causes. However, if you are experiencing the unfortunate “my car won't start after a new battery is installed” condition, this could be due to other causes – like a faulty alternator and not a dead battery. Let’s check out the most common car won’t start symptoms and what you can do to troubleshoot these problems.
The car is silent when you turn the key
If you put your key in the ignition and turn the key to hear the audible clicking sound and hear the engine turn over and it doesn’t happen, this can make you immediately concerned. If this is the case, check the new battery terminal cable connections to see if there are any loose wiring connections or damage. If it starts when you turn on the engine, you might need to check the new battery cables.
Although you are trying to figure out why you are experiencing “my car won't start after a new battery is installed” and determine the battery is not the issue, the alternator could be the culprit.
The car makes a clicking noise and won’t start
If you realize that you have a “my car won't start after a new battery is installed“ condition, this could be due to an improper battery installation in your car from the last person to work on your vehicle – your mechanic. In rare circumstances, mechanics may install a dead battery in your car during a replacement and cause your car to make a clicking noise and not be able to start.
If you realize that you have just replaced your battery, but it still doesn't work, you could be trying to figure out why you are experiencing a “my car won't start after a new battery is installed” situation.
The car cranks, but won’t start
If you hear noises, but your car still won’t start, you need to check the fuel supply to your engine by analyzing the fuel filter, the fuel lines, and the fuel injector to ensure they are all working properly and do not have any holes, leaks, damage, or cracks.
If all of the fuel lines and the fuel system components are in good condition, check the spark plugs and see if they are sending the necessary electrical sparks and timing to your ignition to spur the internal combustion. If the spark plugs are not working correctly, you might feel your car cranking but cannot turn over the engine or start the vehicle.
If you hear cranking, but your car won’t start, you might be experiencing a “my car won't start after a new battery is installed” condition.
The engine starts but dies very quickly.
If you use a car that has a carburetor, then check the choke to see if it is closing and opening at the right intervals. If you have fuel injection, you can’t make this diagnosis on your own and will have to bring your car to a mechanic to see why you are having trouble starting your vehicle. If you realize that your engine starts but dies much sooner than it should and does not provide any performance benefits, you might be having a “my car won't start after a new battery was installed” scenario.
Car won’t start on rainy days
If the problem of “my car won't start after a new battery is installed” only occurs in certain conditions, this could be due to excess dampness inside of the vehicle. Bring your car to a local auto body shop and ask the mechanic to check the distributor cap inside for any wetness or dampness. The mechanic needs to see if the moisture has harmed the internal components.
If this is the case, try to get rid of the dampness by evaporating it inside the cap using an aerosol can of a solvent. By using the aerosol can, you can remove the moisture and prevent the “my car won't start after a new battery is installed” situation from happening again in the future.
Car won’t start on cold mornings
Similar to the “rainy days car won’t start” issues, the car also might not start on very cold mornings due to the choke in the carburetor or a more serious issue directly related to the fuel injection system. If this is the case, you need to bring your car to a mechanic to determine why you have a “my car won't start after a new battery is installed” condition.
Engine misses while idling
Check the spark plugs to see if they are firing at the correct times and providing the necessary spark to power the engine. You should also check the fuel system, like the fuel pump, fuel filter, and carburetor, to see what parts are not working correctly and how to troubleshoot these problems to prevent you from having a new battery but car won’t start without a jump.
When figuring out why you have a “my car won't start after a new battery is installed” condition with your vehicle, there are some main causes as to this issue appearing in your vehicle. One of the main reasons why your car may not start without a jump is the alternator – if this part becomes damaged, a new battery will not help at all, and you will have to determine how to fix the alternator’s problems that are harming your vehicle.
Alternator Function & Symptoms
The alternator generates electrical power and plays a huge part in the vehicle’s charging system. When the engine runs, the alternator must maintain the correct level of charge in the battery and supply electric power to the vehicle’s systems. The alternator is connected to the engine and controlled by a drive belt, directly connecting to the engine’s functions.
Let’s see the signs of a bad alternator in your vehicle that can cause the “my car won’t start after a new battery is installed” situation.
Alternator Voltage Leak
The alternator plays a vital role in converting currents from the alternator into a direct current. Over time, the electricity within the alternator can run out, causing dimming lights. We recommend using a voltmeter to ensure there are no leakages and prevent having a “my car won't start after a new battery was installed” situation.
The most common sign and noticeable symptom, there is a problem with your vehicle’s charging system is a battery-shaped dashboard light. Typically, this warning light comes on when you turn the ignition and then turns off when the engine is started. If it remains illuminated, then there is an issue with your alternator charging system, and you will experience a “my car won't start after a new battery is installed.”
If you hear loud noises when your alternator is running, then the belt or pulley is usually the problem. The belt could be misaligned with the pulley, causing excess friction, grinding, and overheating. If the noise continues after replacing the belt, then you need to replace the alternator to prevent a “my car won't start after a new battery is installed” condition.
Now that you have an idea of what can cause the various conditions for the car not being able to start, you can diagnose and fix the issues before they get any worse in your vehicle. By finding the causes for the engine issues and the symptoms of a “my car won’t start after a new battery is installed” condition, you can quickly and efficiently fix any problem before it becomes more severe and damages your car even more.
