They still only flash up for about a second.

No problem if you could exchange it for a good power supply ;-)

That was suggested to me from Peter C. Wallace (thanks again, BTW)
as well, so I tried it first. Then I pulled the 6 pin connector as well
and cleaned all connectors.
Just to try it out I powered it up with power connectors seated and the
6 pin unplugged. It behaves just like before, so I suspect the
problem is not with the power supply, but with the electronics attached

I was running out of contact spray yesterday and cleaning the contacts
hasn't made it any better. I'll buy some spray at Saturday, but if
all else fails, I'll examine the power supply more closely.
