Please Help T3F problems

I have no direct experience with T3F, but I am under the impression that it was an expensively constructed upgrade of the original Rabco tonearm.  The Rabco was a straight line tonearm that actually relied upon pivoting to make its way across the LP surface. The arm wand was free to move in the horizontal plane. As it moved it periodically closed a microswitch installed at the pivot point. The switch then activated a tiny motor which moved the pivot point along a rail.  Movement of the arm wand associated with the motor drive would then open the switch and turn off the motor until the arm wand arc-ed back to activate the switch again. Your problem could be caused by (1) failure of the switch, or (2) failure of the motor to turn off.  I would suggest you do an internet search on the Rabco.  Perhaps there are Rabco aficionados who are very familiar with your problem and can help you find parts if needed or just show you how to clean the switch contacts.

Dear @scotchboy  : Maybe here can help you:

Thanks guys, I appreciate the fast responses

Ive contacted Goldmund before. They're of no help on TT anymore.

I'll try the Rabco lead and anything else that may come up.

I would bet there are Rabco aficionados out there somewhere.  Meantime, if you can by close examination figure out where those contacts that turn the motor on and off are located, you might try just cleaning them very carefully and gently.
