Technical Wiring

[Semba]

Previous owner has screwed up the wiring from the Radiator electric fan to the Radiator temp switch. All I can do is get the fan to run all the time, or not at all. Can anyone let me know what goes to what?
On the lighter side, it is a 1981 Spider 2000 with 28,000 original miles. Purrs like a kitten, looks like a pit bull.

Hi and welcome to the forum

Rad fan wiring is usually:

Earth -> Thermostat switch -> Motor -> Fuse

But it could be:

Fuse -> Thermostat switch -> Motor -> Earth

First option is best and safest.

Post up a few pics for us
