If the clutch came on when you mechanically tripped the points in the relay, then your problem is in the primary circuit feed that energizes the coil for the contacts
This can be anything from a feed fuse , freon pressure sw, temp sensor, etc...
I have the Clutch Control schematic and will send it jpg. if you email me.
That will tell you the where /whats of each component and the part interior switchings
