Sorry for inconvenience. I just received my order , but I have a problem in using the developed kit. I charged the battery but there is a problem in the operating. No detection for any power.
I am waiting for your support.
Have you measured the voltage with a multimeter on the power connection?
Have you measured the voltage with a multimeter on the balance plug?
If so, can you let us know the voltages. If not, could you test the voltage and let us know? This will help determine if it's a warranty issue or if it's a user problem etc.
thank u
What battery are your charging ?
Battery Care and Charging I do believe your issues will be resolved if you follow that lesson.
Also, you stated you have the developer kit, but it does appear that you do have the JD robot kit. Please makes sure you also review all of the JD Lessons in the Learn Section.
Have you measured the voltage with a multimeter on the balance plug?
By checking the above we can find out where the problem lies, or at least we can get a little closer.
In the back of the JD body, there is a power plug that has two connectors that you plug the EZ-B v4 into them. You have to check the voltage between these two connectors, it has to be about 7.4 - 8 V DC. To do this follow these steps:
1-Charge the battery
2- with the EZ-B v4 not plugged in, turn the switch on.
3- Measure the voltage between these two connectors. BE careful that each test probe of the voltmeter is only touching one connector and they are not touching each other (Do not short circuit the two connector together).
4- If the voltage is zero, this means that the 20 A fuse inside the body is blown out and has to be changed.
May be you need to open the body of the robot. There is four screws that you need to unscrew. Inside the body there is a 20A fuse. This fuse may be broken and has to be replaced.
When you open the body try to memorize how the parts inside it are arranged inside it, this will help you when you reassemble the body.
