Yep, those pesky tants do make a mess when they go!
I'm still having fun and games with this board. IC3 was swapped out and this enabled it to boot. It wasn't stable however and any flexing of the board would drive it potty. The alpha was also corrupt although it was now functioning.
So there was still a way to go and as it had already had remedial work done around the battery area it's likely there are still some tracks damaged somewhere. That can wait till tomorrow.

Moving on I noticed one of the motor driver IC's had been changed and under one of the pins it looked black.

Hmm, this had better come out and I'm not sure I'm going to like what's underneath!
All that carbon has got to go otherwise it will eventually track across. For those of a nervous dispostion look away now.
It all has to be dug out, luckily it hadn't reached the adjacent hole. Once that's done it needs to be filled with epoxy.

When that's dry it can be drilled and riveted. A bit of the old green stuff and it's good to go. Won't need that strap wire again either.
I'm also having fun and games with another board but more of that tomorrow if I get time.
