Well....the car is modified, so I can't say much except that he has a new alternator with internal regulator. I measured the computer supply voltage with a multimeter while the relay is being cycled - no blips or spikes that the analog multimeter can detect. I don't know if that is useful information however. I am leaning more and more towards a problem with the ECU itself. This could be confirmed I suppose with the detailed electronic tests provided in one of the answers received here (connecting diodes, capacitors etc) but I think we will just try it with another ECU.

Thanks!
Greg
