Battery connected backwards to robot

[ngreen]

Our PDP was re-wired in reverse, and we experienced the same clicking sound. Probably 3 seconds before getting to the breaker.

It was an oversight while trying to re-route wires inside a very crowded robot under the time crunch of getting the drive working (after a few mechanical failures).

Luckily, none of the components beyond the PDP were damaged. Actually the PDP itself still worked for us; however, the CAN was fried and we had to replace the PDP as the firmware version wouldn't be communicated otherwise.

At the moment it happened, we thought the damage would be much worse and I think we were lucky.
