Issue with Talons

[JewishDan18]

Hi all, I was hoping to get some help with a strange problem with some Talons.

Tonight we decided to do driver tryouts with a simple robot consisting of a drive train with two CIMs to each side, all controlled over Talons. Normally it drives fine, but occasionally while driving straight the side going forward (the lights on the Talons are green) reverses for a very quick moment, going backwards. The lights on the Talons turn red when this happens. We are using simple Arcade Drive code, and I've checked the values being sent to the Talons in the code, and they are not reversing at all there. This happens when driving straight forward and backwards at full power (so all 4 Talons have had the issue), but not when purely turning.

We think there is an issue somewhere between (and not including) the crio and the Talons themselves, since it happens to all 4. Additionally, once when powering the robot on one side of the robot moved at a high speed for a very short amount of time, which leads us to rule out code issues.

Tomorrow we plan on replacing the Digital Module, the Digital Side Car, and the cable connecting the two one at a time to see if any of them are causing the issue. Is there anything else we should be doing or checking for that anyone can think of? I tried to give all relevant info but if anything else is needed I can provide it. Thanks!

EDIT: Also, going to try swapping victors for the Talons.
