OK ... well, not really ... grounding the green/black pin in the cluster connector brought the fan on, so the fault is in the dashboard. Deep joy. 
All the components look so big in the photo above, so small on the PCB. Doh! Still, if I can source the TR34 replacement based on the info you've supplied this morning, I'll give it a go.
Then again, I might just wire a manual fan switch and leave it at that. I've hardly ever had the fan come on in normal riding, even on the hottest days in Spain. Only when spending ages in traffic and that's very rare for me. I used to have a manual fan for those days anyway, so that I could get the cooling started before the coolant got above 90C.
Thanks again, Christian. You're a star.
