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.

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.

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.

Battery Isn’t Holding A Charge

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.

Charger Poor Contact

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.

Electronics Not Working Properly

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.

Instructions on how to troubleshoot a Dewalt air compressor not working:

  1. Make sure the air compressor is shut off and unplugged from the power source
  2. Remove the oil cap
  3. Using a flashlight and a screwdriver, carefully remove the back cover of the air compressor
  4. Remove the adjustment knob by turning it counterclockwise as far as it will go until you hear a click sound and feel resistance when turning in either direction (usually clockwise)
  5. If you can turn this knob, then check your oil level by looking at your oil dipstick located near where it was removed from before unscrewing it — the fluid should be at least half full, but if low, add some more until it is full again
  6. If everything checks out correctly here, inspect your fan motor for any damage or excessive wear that may cause it not to run properly and replace if necessary (most likely will require replacing with a new one)
