Car Has No Power At All Even With Jumper Cables

Do you know Why Does Car Has No Power At All Even With Jumper Cables? Your automotive could have a dead or drained car battery for a variety of reasons. Age, poor quality or it’s simply that they will have suffered damage from prolonged deep discharge and other reasons.

When your automotive has a dead battery, the answer that’s typically recommended is to jumpstart it with a collection of jumper cables and permanent reasons, it’s low price and effective! What if it shows no signs of power? No radio, interior, or dashboard lights with the key turned and therefore the jumper cables properly connected?

How To Fix Car Has No Power At All Even With Jumper Cables

What Should I Do When Car Has No Power At All Even With Jumper Cables?

If your automotive isn’t able to begin and has no lights even when connecting jumper wires then its electrical system isn’t receiving power from the battery. Assuming that its battery is dead and you’re relying on another automotive (with a charged battery) to charge it then as a primary step:

Method 1

Check and make sure that the jumper cables are intact and not damaged on their length. You may get to swivel then so they turn over the battery post for an honest firm connection.

Method 2

Examine and clean the battery posts of the dead battery and remove the greenish-blue powder which will have been designed upon the battery cable clamps and posts. Make sure that the battery posts are firmly connected.

Simple Checks You’ll Be Able To Do If Automotive Has No Power (With Jumpers Connected)

Method 1

Examine the jumper cables on their length to substantiate that there’s no damage and ensure they’re firmly connected to the battery posts. On the automotive with the flat battery, make sure that the black jumper cable is connected to the exposed metal of the automotive chassis.

Method 2

Ensure that the battery posts and battery clamps on either of the automotive batteries are clean, don’t have any corrosion, and firmly connect with the battery posts

Method 3

Make sure the battery ground connection on the dead car’s battery is firm and makes clean contact.

Method 4

Make sure the drained battery is not shorting. you’ll need to take it out, charge it and have it load tested too.

When Your Automotive Might Not Have Power Even With Jumper Cables Connected

Method 1

It’s Loose or corroded car battery terminals. If any of the battery cables are loosely mounted or corrosion has built up around the posts or cable clamps, then-current flow is restricted as a result of the high resistance created, and also the automotive can haven’t any power in any respect.

Fix. Clean the powdery residue off the connecting wires by pouring baking soda mixture over the terminals and brushing it off. Finally, apply to pour grease or Vaseline on the clean battery terminals to guard the metal against fumes before reconnecting the wires back to the battery terminals.

Method 2

The automotive has a loose or broken battery ground affiliation. If the battery ground connection is broken then your automotive won’t receive power in any respect. You can also measure the voltage with the positive probe of a good quality meter connected to the battery positive measure negative, first at the negative battery post and so at the engine block. The voltage ought to be constant. A difference in the voltage indicates a break within the cable.

Method 3

The car battery has an interior short. If the car battery is shorting, then it’ll starve the rest of the car’s electrical systems of engine block even with the jumper cables properly connected. You’ll possibly see an outsized spark once the last battery connection is formed if the drained battery is shorting.

A sign that there’s a high-power draw from the charged battery. Another sign to appear is the temperature of the battery. A battery with an internal short can become hot once connected to a charging supply like a charged battery.

Method 4

Broken jumper wires. although not common with sensible quality jumpers, a break within the jumper wires (under the insulation) stops the flow of power to the automotive with a dead battery.


If Car Has No Power At All Even With Jumper Cables, then you ought to check the following: broken jumper cables, jumper cables not firmly connecting to the battery posts, corrosion on the battery posts, bad automotive ground, or a shorting battery.

Frequently Asked Questions

What would cause an automotive to have no power at all?

Possible causes of a power failure might be either bad battery connections, a bad ignition switch, or a bad alternator. What you wish to try and do is check your vehicle’s power sources.

Why is my automotive not starting even with jumper cables?

If the automotive starts at once, your downside is most likely a dead battery. Charge the battery and clean the terminals and cable connectors to make sure smart contact. If your automotive doesn’t begin by jump-starting, you will have a problem along with your starter, alternator, or another element of the electrical system.

What to do if your automotive has no power at all?

In your situation, you’ll go remove the battery from the vehicle and take it to possess it tested. If it’s dangerous, simply replace it and drive the care home. Throughout this method confirm the battery cables, ground affiliation, and connection to the starter are all clean, dry, and tight.

Can a completely dead battery be jumped?

No, the battery cannot be too dead that it cannot be jump-started. 1st of all, this can be a chemical element. So, naturally, it cannot simply “stop working” while not one symptom. there’s not a chemical reaction that would immediately interrupt itself below these conditions.
