Hi all' I have just successfully repaired my seat ecu. I had to replace the battery with a 3.6 nmh plus 3 capacitors a couple of resistors etc. I used a multi meter to check the continuity of the tracks and found that about 4 tracks had been compromised by the batteries decay. These tracks I soldered copper wire form point to point to join the tracks. I have never attempted anything like this before and to reinstall to find every thing working was an amazing feeling.
