[TowerTalk] Tri-Ex LM-470 Tower Limit Switch Operation

[Larry Essary]

I have just about finished my re-furbishing and installation of my LM-470 tower.

I was working with the motor today.    The tower goes up and down and the lower limit switch works
but the upper limit switch does not.  The tower keeps going up once it trips the upper switch.  
If I remove the upper limit switch cable from the controller  the tower will not go up at all.
My assumption is that the upper limit switch is working properly and the problem is in the controller.

Anyone have any ideas on this problem ?

Also... are the motors on these towers VERY noisy ?   Mine makes a LOT of noise.

tnx,
