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?

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.
