Looks like this has had a miserable time in the past but a nice project after we finish the Locomotion

Right just started looking over my boards
I have already got a working replacement for the driver board as that was in a really bad way (but apparently still worked)

The CPU board doesn't look good on the 2 back corners so my questions are

1. Do I just connect all the ground traces up and leave it at that
2. Leave it as it is and see if it works as apparently it did the last time with was powered up.
3. Replace the board and have a spare
