Thanks for the direction. I tried the non-operating motors on the M1 terminal and they both ran fine, so the motors are good.

I called Dimension Engineering and spoke to Charlotte. She came to the same conclusion as you that the controller is toast. She sent am RMA for me to send back the controller and they will diagnose the problem and either repair or replace the controller.

I’ll let you know what the verdict is.

And a bit of chiding is owed you…the capacitor thing is really disturbing since the instructions say to install them straight away. I would change that to keep the same thing from happening again. Just sayin’…. :)

I appreciate your help. The controller I have installed is the 2×25 and was upgraded on the advice of the sales guy I talked to when I placed the order. The damage from the capacitors may be the issue, but the machine ran perfectly after removing them and only stopped working correctly after I charged it.

I understand these things aren’t an exact quantity and I’m sure we’ll figure it out. My biggest concern is that this robot is going to be put into service and needs to be able to be charged without the drama I am experiencing now.

Could you look into the 2×32 controller and see if its voltage threshold is higher than the 2×25? Thank you for the help.

OK. I disconnected the RC receiver and the affected motors (Same side). No change. The red error LED is still flashing. Checked voltage at terminals strip for each side and the affected side gets 0 volts and the good side gets 21.4. Either the controller has gone belly up or the high battery voltage is not allowing it to operate normally.

I am looking into ways to drain the battery down to a more reasonable voltage and see if that solves the issue. All was running perfectly until I charged then battery packs.I was led to believe that the DEScribe software would allow me to change the high voltage threshold to prevent this from happening, but apparently that is not the case. I have the high voltage set at 31 volts

This is getting ridiculous…..

boombaby31,

Spot on. That took care of it. I watched the video and it made it look like it was a necessary part of the wire-up. Thanks for the help. :)
