We checked the shelf. The TS-80 servo has 3 wires. Your servo has a problem of some kind. If it's a Tower Hobbies TS-80 servo, you can send it to us for service.
Mystery solved!!
As always, you guys were correct.
This is the story:
The TS-80 was given to me for a video boat project.
I need a BIG servo to turn steer the air prop and the motor.
The TS-80 was used in a robot as a wheel motor.
The user had wired a black and a red wire directly to the motor terminals.
When I opened it up, I saw only 2 solder points and nothing else.
After you guys convinced me that there really should be 3 wires, and after a call back to Tower Hobbies (Who had the 2 wire photo on their web site), who confirmed the 3 wires, I got serious.
It took me about ½ hour to unsolder the leads and to lift up the circuit board.
Lo and behold! The guy had tucked all the original 3-12” wires and the connector beneath the board.
He had ‘floated’ the potentiometer away from the shaft key to eliminate any stops.
I put it back together as designed.
FINALLY!!!
Thanks all for your input and for your patience.
