Question about Celestron NexStar 114GT (269 x 114mm) Telescope

1 Answer

Motor for elevation does not run. The traverse motor will run for a few seconds then quits and won't restart. I've replaced batteries repeatedly. The unit is about 10 years old but has only been used once due to eye issues. It has been kept out of the dust and all electrical battery contacts are in new condition. The unit is a Nexstar 114 GT.

How do I calibrate elevation grade for treadmill?


Hey there, sorry to hear you're having an issue with your elevation motor. I would be happy to help you solve the problem.
Since you already installed your motor you can go straight into diagnostic mode.

To get into Diagnostic Mode on your L8
Make sure to turn off your treadmill.

-ET's - Press Menu and Start at the same time
-CT's - Press Manual (or Display^) and Start at the same time
-All other L SERIES mills - Press Display (or display and Start at the same time

SideNote-
-*CT's that were manufactured after 09/2003 - Press Display and start at the same time.




Few things you want to do, if you haven't already.

A. Align the motor with the clevis mount and install the motor mounting pin.

B. Insert hitch pin.

C. Reconnect the elevation harness to the lower board

D. Set the lowest limit switch by holding the UP elevation button for 5 seconds. Then press and hold the DN elevation button one more time to make sure you only hear a click.

E. For L7/L8 machines; Thread the elevation nut to where its flush with the threads on the "worm' shaft.

F. Mount the elevation nut to the leg assembly by lining up the holes on the leg assembly. You may have to move the leg assembly so that the holes on the elevation nut line up. Then slide the two elevation pins through the elevation assembly and into the elevation nut. then secure the pins with the 2 set screws.




To calibrate your potentiometer you can try to adjust while it is installed but for best results you must calibrate it before its in your motor housing.







G. Calibrate the elevation potentiometer and to do so you must;
1st: Visually confirm treadmill is leveled. (0% grade)
2nd: Adjust the settings as follows;
All L SERIES millls should read 0.0
3rd: If the setting is incorrect, follow these steps.
Step 1: Turn the post of the potentiometer all the way
CLOCKWISE.
Step 2: SLOWLY turn the potentiometer COUNTER
CLOCKWISE until the setting is correct.

H. Carefully install potentiometer into the motor housing
*NOTE: The setting may vary when inserting the potentiometer
into the motor. As long as the change is minimal, fine
adjustment can be achieved by rotating the meter
while inside the elevation motor.

I. Press OFF to turn treadmill off. Then restart the machine in manual mode to TEST elevation after resetting your potentiometer. As long as the change is minimal, fine adjustment can be achieved by rotating the potentiometer while inside the elevation motor.


For more Diagnostic features and possibly further detail, I will be attaching a Link to your machines service manual. I hope this helps, always hear to help. SportSmith.

It's the fan motor. A relay problem would cause the motor not to run at all.

2009 Traverse, the engine cooling fan remains on for @ 1 minute after switching off the engine and removing the key from ignition. Is this normal and if not what is the problem. Thanks.


That is absolutly normal, the fan is designed to run at a certain temperature not just when the motor is running. On short trips or cool weather the fan won't run at all till needed.

My Tunturi Treadmill ramp is stuck in the top elevation position and will not run. I get a "Auto Syncing" message, but the machine will not run. Have tried unplugging etc, but it will not exit the mode...

Press ‘ELEVATION DOWN’ to decrease the elevation to minimum percentage 0% Press ‘SPEED UP’ to increase speed value and ‘SPEED DOWN’ toto decrease speed value. Press ‘ENTER’ to repeat above test or ‘SELECT’ and ‘ SPEED DOWN’ buttons simultaneously to return to the normal mode

Switch off the treadmill and unplug the power cable 3. Remove motor cover 4. Fold up the running deck 5. Loosen two screws (A) attaching the lift motor nut (B) to the incline frame 6. Adjust the lift motor nut (B) so that there is 9 mm (.358 in ) gap between the upper end of the nut and the lift motor frame Tighten the screws (A) and verify correct elevation by measuring Adjusting lift motor to 0% position 2.76in 12% position 9.646 in measurement taken from floor to bottom of motor compartment frame.
