Question

Hi, 

I purchased in Feb. 2019 a new JD robot, just used a few times

Yesterday, I was doing the servos profile, the robot twisted up and said low battery (it was charged first) then a burning electrical smell, I shut it off

I recharged the battery, all seem ok now -  do you know what that could have been? 

Used it this morning ,robot is working fine now

update:

robot will not turn on - dead  3/6/2019


I replaced the fuse as you suggested to no avail, still dead, what do I do?

you have to let the batt cool down for 30 minutes before power on the robot.also when you have used the robot,let the batt cool of for 30 minutes,
before charging.great to see you tackle the problem.howlong did the charging last before the batt was fully charged.?
if you can use a multi meter ,you can messure howmany volt there is in the batt.

It looks like the Battery is good, since the charger has a green LED. That would indicate that the battery can be charged and it is has a full charge. I believe the EZ-B protection diode may have been damaged during the event that happened when JD was twisted up. It's likely that all you need is a new EZ-B.

I believe Robotshop may have replacement items that they can send you. Probably best to contact them before sending a robot back to them.

There is a polarity protection diode on the EZ-B main board.

Hey guys,

In the picture is the WiFi (top) board, the polarity protection diode is on the bottom (main) board. The diode is not user serviceable. It's easy to spot, it's right near the voltage input.
