Thanks VolvoFarmer & Basil....It just seems so weird with a frame that strong that ya can't exceed a certain weight, eh? Guess it's because of the torque of the actuator and what weight it can move? And, on the actuator itself, I only have the red and black wires for dc power, none for the limit switches!! is this an internal deal inside the actuator? Thanks again, guys....
P.S. I tried to include a photo of the rough tracker, but I can't get it to post, but its in my files. oh well............Bill
