At competition our New Rev PDH kinda “blew up.”
Context: We’ve been having issues all season with comms, etc. Later in the build season we shorted one connection by accident and popped the fuse. No big deal, just replace it, that’s what it’s meant for right? But then we had a hardware error (CSA Fault) which Rev assured us was okay to operate on. All that does is report current to the client, and they said the PDH would operate normally, so we went to competition.
Throughout competition we had issues. Especially towards the playoff matches there were constant brownouts and loss of communication from the constant resets mid match. Our robot was performing terribly and we couldn’t find the source of the issue, until we could smell the burning.
right before our, to be, final match the FTA’s, LRI’s, CSA’s were no the field trying to see what was up with our robot because it reeked of burnt something. They couldnt find anything so they let the match go on. After we lost our tiebreaker (partially because for the majority of the match we were just sitting unable to move), we started sniffing around to find that the positive main battery wire was “welded” to the terminal and burnt into it on the PDH. We’re going to hop on a call with Rev later this week/earlier next week but right now we’re putting all the OEM CTRE parts back on and getting our robot operational again.
My question - could the one short have contributed to this slow decline to everything going wrong (mod note: edited for profanity)? Has anyone else had issues with the new PDH like constant sticky faults, etc? I just want to know where we could’ve gone wrong?
