Before answering the question of if you can start a car without a battery I will give you a quick explanation about the car’s electrical system. A car’s electrical system consists of its battery, alternator, and other components like the magneto ignition and so on.

The battery is used to start anything that needs power while the alternator grabs additional power from the engine and tries to restore the battery.

While a magneto ignition which can also be called a high tension magneto is a magneto that gives current for ignition to a spark-ignition car like a petrol car, It also provides pulses of great voltage to the spark plug.

From the explanation, we should be able to detect our answer. But it might be confusing so I will answer the question.

Can You Start A Car Without A Battery? Yes, you can start a car without a battery but it depends on the type of car you have. You can start a car without a battery if it has a high-tension magneto.

But if the magneto is absent in the car – it won’t start. The reason is that the alternator is designed to convert mechanical power from the engine to electrical power.

It converts power but does not store power. But the high tension magneto gives current to the car for ignition so you can start your car without a battery.

You Can Start A Car Without A Battery By Jump-Starting It

Step 1

Check The Battery

Be sure that the battery is the issue

Scan the headlights, are they dull or bright? Though in some cars you need to start the car to check the headlights. If they are dull then your battery is probably the problem but if they are bright then you do not have a battery problem and jump-starting the car will not be of help.

Be sure the doors will open when you press the button on the key, or attempt to open the door from the outside. Check the internal lights function and if there’s an equipped clock or Gps turned on.(Read Also: Can You Start A Car With A Battery Tender Connected? Find Out)

Set the key to start the car and see if your dashboard brightens up as usual. Run a quick test on the stereo, most times with a low battery you will be able to see some dashboard light and obtain some sound out of the stereo. If in any way you do not get a flash out of the dashboard you may have an issue with the start switch.

Attempt to start the car does it turn around very very slowly or grouch rapidly? If it does grouch rapidly, you do not have a battery problem, and jump-starting will not help. If it grouches slowly or not at all you probably have a problem with the battery or a dead battery.

Step 2

Unwrap Each Of The Car’s Hood And Track Down The Battery

In most cars, the battery is closer to the front of the car probably on the left or right side but in some cars, the battery is fixed near the firewall between the engine and passenger cabin while in other cars the battery is fixed in the trunk. If you aren’t sure of where the battery is fixed you can check your car manual. Also, know the positive and negative terminals.

On the battery, the positive terminal is noted with a plus sign and it usually has a red wire connected to it, While the negative terminal is noted with a minus sign and has a black wire connected to it. (Read Also: Can I Start Car With Battery Charger Attached)

Step 3

Park The Working Car Close But It Must Not The Impaired Car

Park the car in a route where the space between the two-car batteries is small then put off the car lights and other electrical power components in the car (be sure to do the same in the impaired car too). Ensure that the two cars do not touch each other.

If you allow the cars to touch each other, jumping the battery will cause a very risky electrical hook between the cars. (Read Also:Should Alternator Pulley Spin Freely?)

Step 4

Wear Safety Gear And Gloves If You Have

Examine the batteries for breaks, leakage, or other defects. If you see any of these things mentioned do not jump-start the car.

You must remove the disabled car battery wires from the battery terminals and clean them both by using a stuffed wired brush to remove all eroding and reconnect the wires to the terminals to be able to jump-start the car.

Take out any positive red protective lids if favorable.

Step 5

Straighten And Unwind Your Jumper Wires

Just like the battery, your jumper wire might probably have the red and black cord and will have heavy-duty clasps to connect the terminals. You have to make sure that the red and black ends of the jumper wires must never brush each other immediately when they are connected to the batteries.

Step 6

Bind The Jumper Wires In The Following Order That Will Be Listed Below

Bind one red clamp to the positive terminal of the lifeless battery – Bind the other red clamp to the positive terminal of the good battery – Bind the black clamp to the negative terminal of the good battery.(Read Also:Can A Bad Alternator Cause Transmission Problems?)

Also, bind the extra black clamp to a part of the ground metal on the other lifeless car, the clasp where the hard negative wire from the battery binds with the structure.

If that’s not logical look for any metal not painted or greasy that is connected to the car – normally a bolt or other bulging metal will work. You’d notice a small spark when connected to good ground. For a final alternative, you can connect to a negative part of the lifeless battery.

Step 7

Start The Working Car

Allow it to wait for a few moments, do not race the engine but accelerate the car a little above the wait for 30 to 60 seconds. You can do this by charging the battery in the lifeless car because the ignition in the lifeless car will attract most of the needed current from the battery, not through the wires.

Step 8

Try To Turn On The Lifeless Car

If it does not turn on, shut down the car and disconnect the last connection for a short period while you narrowly twirl each of the clamps to assure a good connection. Restart the working car again and stimulate another 5 minutes for charging before attempting to start the lifeless car if this does not work you may need to change the battery.

Step 9

Take Away The Jumper Wire Once The Car Starts

You can do this in the setback of the order in which they were bonded and do not let any of the wires touch each other.

Step 10

Keep The Recently Lifeless Car’s Engine Running

Start the car above by slightly accelerating up with your foot on the gas for five minutes and above wait for 20 minutes before turning off the engine. this should have given the battery enough power to start again and if it does not you probably have a dying alternator or a bad battery.

Organize your friends to the back of the car and tell them to get prepared to push.
Take your position in the driver’s seat and start the car
With the parking brake still connected, press in the clutch and move to the second gear the first gear is not advisable because it may make the car clam harshly.
Push the brake pedal and free the parking brake.
After freeing the brake, tell your friends to push.
At 5mph free the clutch unexpectedly, the engine might stumble as the engine tries to engage.
If the engine starts, then you are done. But if it doesn’t – retry the step at a higher speed. And if it doesn’t start then the battery isn’t the problem.

Using The Jump Start Box

A jump box is an important small lightweight battery with a jump wire attached and they also use software to avoid voltage stakes that could harm your car’s electrical system. They are more comfortable than a jumper wire, some of them come with onboard safety lights and some other things.

How To Use A Jump Start Box

Be certain that your jump starter is well charged. If it’s not well-charged, plug it in and charge it as directed.
A new jump-start box comes with an integrated wire but if it’s not with it, connect your wires to the positive and negative terminals on the jump starter.
Bind the red clamp to the positive terminal of the dead battery and also bind the black clamp to a sustained metal surface somewhere on the frame of the car.
Immediately everything is connected, turn on the jump starter as directed, and after a minute or two start the car. If the car doesn’t start let it sit for a few minutes to give the battery time to charge and attempt it again.
Immediately the car starts, turn off the jump starter, and remove the clasps in backward order.

Dead Car Battery Tricks
