Yes I saw the ebay ECU. I'd rather try Honda for a new one at £500 than risk my money on that one.
I have taken a day or two off from the ECU to relax a little. Yes I know they have polarity, and I thought I had them all the right way round. But sometimes in a disappointed state mistakes can be made so I will check again. Then check the soldering and test the caps.
Tracks seem ok but again, I shall check.

Cheers for your replies guys
