A500 memory upgrade card busted?

[Rhuantavan]

Hi,

I have an (1MB?) battery-backed clock memory expansion card for an A500 and have replaced the leaked battery with a new one. However, when turning the thing on (with the mounted switch) and powering the amiga, the expansion started to smoke. In the first picture you can see the blackened thin trace on the lower left edge of the board %&$#?@!%&$#?@!%&$#?@!8211; that's where the smoke was coming from.

Can anybody suggest what is to be done? I can solder, but don't have much knowledge of electronics. Thanks!

I have attached the images.

Yes I could pick up a replacement, but where's the fun in that?

Sigh, I hoped there was a way for me to repair it as money is tight.
