Once again, I am not familiar with the particulars of the wiring of the 1980
Spitfire fan circuit but a few general comments. Check the grounds. If the
fan and the fan relay share a ground and the ground is problematic this could
cause what you are seeing.
The power source to the relay is most likely a large brown wire. If you ran
a different wire back to the battery to replace this feed you could eliminate
problems resulting from problematic connections in the brown wire circuit.
Try these and report back.
