Resetting The Charger
Seeing your Dewalt battery charger blinking red can be frustrating. Before you panic, try resetting the charger. This simple step can often solve many issues. Learn two methods to reset your charger: Power Cycle and Factory Reset.
Power Cycle
Power cycling is a quick and easy method to reset your charger. Follow these steps:
- Unplug the charger from the power outlet.
- Wait for 30 seconds.
- Plug the charger back in.
This process helps clear any temporary issues. Ensure the charger is connected properly. A secure connection is crucial. Check if the red light stops blinking.
Factory Reset
A factory reset can solve more persistent issues. Here are the steps:
| Step | Action |
|---|---|
| 1 | Unplug the charger. |
| 2 | Remove the battery. |
| 3 | Press and hold the reset button. |
| 4 | Plug the charger back in. |
| 5 | Release the reset button. |
The factory reset returns the charger to its original settings. This method helps with more complex problems. Ensure you follow each step carefully. Check if the red light stops blinking.
Using A Multimeter
If your Dewalt battery charger is blinking red, it might indicate a problem. To diagnose the issue, you can use a multimeter. This device helps you check the voltage and current of your battery. Follow the steps below to understand how to use a multimeter effectively.
Voltage Check
First, set your multimeter to measure DC voltage. Connect the black probe to the negative terminal. Connect the red probe to the positive terminal.
Now, read the voltage displayed on the multimeter screen. A healthy Dewalt battery should show a reading close to its rated voltage. For example, an 18V battery should read around 18 volts. If the voltage is significantly lower, the battery may be faulty.
Current Check
Next, you need to check the current. Set your multimeter to measure current (Amps). Be careful as this step is trickier.
Disconnect the battery from the charger. Connect the multimeter in series with the battery and the charger. Place the black probe on the negative terminal and the red probe on the wire coming from the charger.
Read the current on the multimeter screen. A healthy charger should show a steady current flow. If the current fluctuates or is zero, there may be an issue with the charger.
