Re: unknown electrical issue

Would you mind posting the Driver Station Log from the video (or any instance of this happening)? The logged battery voltage is something I would like to take a look at.

My first instinct is to check the battery and how many Amp-hours it will still hold since it has been used. A brand new battery is generally at 17 Amp-hours. The lower the A-Hr, the faster the voltage on a battery will drop. A full battery dropping to 11V after 3 minutes is not unheard of, but not common either.

Does anyone see the RSL (Robot Signal Light) flash in the video? I am not seeing it flashing or are momentarily blind (or both). The jitter could be a low battery undervolting the sidecar, but without the Log file, it is just speculation.

Any FTA's, FTAA's, CSA's, or anyone else are more than welcome to throw out other ideas.
