Clutch fried; as tested...
Pulled the wires from the clutch and tested them, no short.
Henceforth, the clutch is fried.
Bought a new clutch and wiring loom (the old one was stiff and the insulation was cracking all over the place), and got a tech to do the job.
Total cost of job :
New Fan clutch - $65.00
New Wiring Loom - $15.00
Labour - $30.00
Short circuit in previous circuit did not short out any wires (tested today) but was due to the defective clutch itself.
Money well spent, now the running temp in stop-go traffic is around 83 deg C.
Well done. Any one for the books...
