If our robot is enabled but with zero input, there is a constant 40 amp draw. It is causing us to drain the battery extremely fast, causing brownouts due to low voltage as early as 30 seconds into the match. We suspected it was the PDB, but we’ve replaced the entire board and all the fuses and it’s still an issue.
We asked other teams at the same event (Bloomington) and there are two others with the same problem.
If anyone has had this problem and knows what it is or how to fix it that would be awesome as everyone here is completely stumped.
