Dewalt 1400 jump starter troubleshooting

If Dewalt 1400 jump starter does not work, first, check the battery charge. If the battery is low or dead, the jump starter will not work. Make sure to have a full battery before trying to start the unit.

If the battery is fully charged, try connecting the charger to another power source and then try starting the unit again.

If it still does not work, there may be a problem with the jump starter itself. Contact Dewalt customer service for assistance. It may be time to replace it. Dewalt offers a warranty on all of their products, so feel free to contact them if you need assistance.

Some of the most common Dewalt 1400 jump starter problems and solutions:

1. Bad battery: If your battery is bad, you will need to replace it. To do this, open the battery compartment and remove the battery. Then, replace the battery with a new one and close the compartment.

2. Faulty charger: If the charger is faulty, it may not be able to charge the battery. To check this, connect the charger to an outlet and turn it on. If the light on the charger turns green, then the charger is working properly. If the light doesn’t turn green, then you will need to replace the charger.

3. Damaged cord: If your cord is damaged, it may not be able to transfer power from the generator to the battery. To check this, disconnect the cord from the generator and plug it into another outlet. If the generator starts up now, then your cord is probably damaged and needs to be replaced.

4. Broken switch: If you see that there is something wrong with the Dewalt jump starter, then it might be time to replace the switch. This is an easy fix, as you can buy a replacement at any electronics store and install it in just a few minutes.

5. No power: If your battery does not provide enough power to activate the jump starter, then you will have to get a new battery before you can try again. You can find one at any local auto parts store or even eBay or Amazon.

6. Low voltage: If your Dewalt 1400 jump starter has low voltage, then it could mean that there is some kind of problem with the main battery pack or charger unit itself. This is another good reason for getting a new battery pack as soon as possible because once this happens, it can be very hard to fix and may require replacing other parts as well (such as the charging circuit).

Dewalt 1400 jump starter won’t turn off

If you are having trouble trying to get your Dewalt 1400 jump starter to turn off, there are a few possible solutions.

  1. Make sure the battery is fully charged. The battery in a Dewalt jump starter should be at least 3/4 full to function optimally. If the battery is low, it will have less power to turn the motor off when you press the button.
  2. Verify that the ground connection is good. If you are experiencing issues with your jump starter, it may be because there is poor ground connectivity between the battery and the motor. Test your ground connection by shutting off the power to the unit and touching both metal parts together (like from an electrical box) for a couple of seconds. If it doesn’t spark, there may not be enough resistance between them and your jumper might not work correctly.

Dewalt Dxaeps2 jump starter problems can be broken down into 3 main categories: battery, charger, and electronics. In this Dewalt jump starter troubleshooting guide, we will walk you through each step of troubleshooting your dewalt dxaeps2 jump starter.


The most common issue with the battery is that it’s not holding a charge. The most common cause of this is overcharging. This can be caused by either leaving it on overnight or letting it sit on the charger for too long. If your battery is not holding a charge at all and you’ve tried charging it for an extended period of time before performing a jump start, contact us for more information about what could be causing this issue.


The second most common issue with the charger is poor contact between the plug and the receptacle. This can be caused by dirt or debris in the area where the two connectors meet, which prevents proper contact between them. If you notice that your charger isn’t making good contact with your Dewalt Dxaeps2 jump starter’s receptacle, try cleaning out any dirt or debris that may be present on both sides of the plug itself (the side that touches your socket). If this does not resolve your problem, contact us for more information about what could be causing this issue.


The electronics of your Dewalt Dxaeps2 jump starter may be causing problems for you if they are not working properly or not working at all when plugged in. These include things like the LED lights on the device, charge indicator light on the power bank itself, and any buttons used to control its operation such as:

  • On/Off button
  • Charge indicator light
  • LED flashlight button
  • Reverse polarity protection (RPP) button
  • Cyclic charging protection (CYCP) button.
