es40 Posted November 10, 2019 Share Posted November 10, 2019 I bought a used ES4 that died after briefly showing a red wrench on the display. This happened a few days before but powered right back on. The power button does nothing and no lights appear when charging, not even the ones on the extra battery pack. I can see a blue light that flashes when looking up the tube from the bottom. All of the connections are secure. I have not pulled out either circuit board yet. Could it be a bad dashboard? If a dashboard is unplugged, should you still see the battery pack charging? Quote Link to comment Share on other sites More sharing options...
cloudust Posted November 15, 2019 Share Posted November 15, 2019 do you see an error code? Quote Link to comment Share on other sites More sharing options...
