Celestron drive on 10" SCT

Its not a "Starhopper 10" but that's the only imput that worked. when switched on, the drive performs the self diagnostic check, 16 ex becomes the default, then the machine slews West at a rate of four seconds to the field of view at 40 X., then pauses for two seconds before repeating the slew. This continues, irrespective of imputs. Changing the speed has no effect. Help! Mike

    Firstly, I re-posted this as I had given you some wrong info - my fault, so I thought I had started again. but that screwed up the fixya system.

    Its a Mead LX200 EMC of unknown age. Can't find any updates, (don't know where to look) and batteries out all night did not work.

    The references seem all to be re "autostar" but all references in my manual are to a
    LX 50 Hand Controller.
    If that can be updated, I presume I would down load what? There doesn't seem to be anything on the site. I would need some sort of cable to move any download from PC to controller?

    I'm thinking perhaps I should ask an electronics engineer to try to fix it?
    Or might there be an option to replace its "brain" ?
    Any off the shelf bits that might work?

It sounds like the telescope has some kind of corrupt instructions it is trying to follow every time you turn it on. Obviously it's being caught in a loop. Since you can't control it to edit those, this is going to be a headache. There should be instructions to do a factory reset in the instruction manual - they may not call it that, but basically you want to restore the settings it had when shipped. Try that, if you can. If that doesn't work, it may be because this model's factory reset is not a true full reset. There are a few settings that are unaffected by it. However, if you can find a firmware upgrade, it will reset those settings. I was unable to find an appropriate upgrade to your firmware, but you may have better luck. Also, when I say "upgrade" it doesn't actually have to be an upgrade. Reloading the same version you have now would do the trick. If neither of those work for you, there's always the old trick of cutting power. Remove batteries and any external power source, and levae it that way overnight. That should be long enough for anything in static memory to be lost, and might just do the trick.

    I haven't been able to find anything about a factory reset for that model. However, I did find some firmware upgrades, with detailed instructions. You have to scroll down a bit to get to the part of the page you need. Start reading where it says "How to upgrade your handbox"

    Hope that helps.

    Yes, you would need a cable... I've never worked with this model in person before, so we're starting to get past my level of expertise here. I'm really not sure what kind of cable it would require, or where you would get it. I assume it would be USB on the computer end.

I could see one window not working from a broken wire inside the door flex , but not both back windows . Back windows are controlled by LF door module . Both back windows have different grounds - LR G200 an RR G201 . Also both rear window switches have different power supply's .RR switch fuse # 18 30 amp . LR is fuse b# 9 40 amp . Both window motors or switche's going out at same time ???? wouldn't think so .
  • Driver door module circuits open/shorted.
  • Loose, corroded connectors.
  • Damaged window regulator control switch.
  • Damaged window regulator electric drive.
  • Open fuse in fuse junction panel Fuse 39 (10A), 28 (10A), 30 (10A).
  • Open fuse in power distribution box Fuse 9 (40A), 10 (40A), 8 (40A).
  • Glass, Frames and Mechanisms

    Inspection and Verification
    1. Verify the customer's concern by operating the power windows/heated back window to duplicate the condition.
    1. Inspect to determine if one of the following mechanical or electrical concerns apply:


      VISUAL INSPECTION CHART Mechanical Electrical
      • Front door power window regulator damaged.
      • Front window run damaged.
      • Front door window glass out of window run.

      • Open fuse in power distribution box Fuse 9 (40A), 10 (40A), 8 (40A).
      • Scratched grid.
    1. If inspection reveals an obvious concern that is readily serviced, correct the concern before continuing with Inspection and Verification.
    1. If the concern remains after inspection, connect the Rotunda New Generation Star (NGS) Tester 007-00500 or equivalent to the data link connector (DLC) located beneath the instrument panel to perform DATA LINK DIAGNOSTICS test. If the NGS responds with NO RESPONSE/NOT EQUIPPED for the driver door module, go to Pinpoint Test A . If the NGS responds with NO RESPONSE/NOT EQUIPPED for the lighting control module, go to Pinpoint Test B . If the DATA LINK DIAGNOSTICS test is passed for the drivers door module and lighting control module, retrieve continuous DTCs and execute Self Test Diagnostics for the driver door module and lighting control module to retrieve current DTCs.
    1. If self test is passed and no DTCs are retrieved, go to the Symptom Chart to continue diagnostics.
    1. If DTCs are retrieved, go to the Driver Door Module (DDM) Diagnostic Trouble Code (DTC) Index or Lighting Control Module (LCM) Diagnostic Trouble Code (DTC) Index to continue diagnostics.
    1. If the driver door module cannot be accessed by the NGS, GO to Pinpoint Test A . If the lighting control module cannot be accessed by the NGS, go to Pinpoint Test B .

I have a 1998 Chevy Blazer 4dr. The 4 whl drive switch does not light up. Some how the 4 whl drive got ingaged and now it is stuck there. I have a new switch on order but this is getting ridiculous. When...

The New Venture Gear Model NV233 is an electronically controlled optional transfer case for use on four wheel drive T trucks. The driver selects 2HI, 4HI, or 4LO by pushing one of three illuminating shift select buttons mounted on the instrument panel. The shift select buttons display the transfer case mode and range, self-test, diagnostic trouble codes, and electronic shift mechanical engaging problems.
During normal driving the transfer case is in the 2HI mode. When the transfer case is in the 2HI mode. When the transfer case is in 2HI both the 4HI and 4LO switch circuits are open, and both lights are OFF. When the four-wheel drive shift select button has been pressed, the four-wheel drive indicator lamp under the sift select button turns ON when the front axle has engaged. The shift select button will blink while the front axle is engaging. This is a normal condition.
The shifting of the transfer case is performed by a motor/encoder that receives drive signals from the transfer case control module (TCCM). When the driver selects one of the transfer case shift select buttons, request signals are sent to the TCCM. If the correct input signals exists, the TCCM will send drive voltages to the motor/encoder. The motor/encoder will position the transfer case to the ordered shift position.

Transfer Case Control Module Description
The TCCM performs the following functions:
• Receives input signals
• Processes the signal information
• Develops output signals
• Sends the output signal in order to control the shifting of the transfer case
The TCCM receives input signals from the following sources:
• The transfer case shift select buttons
• The NSBU switch on the vehicles with automatic transmissions
• The clutch position switch on the vehicles with manual transmissions
• The vehicle sped sensor calibrator module
• The encoder/motor range and the mode feedback signals
• The diagnostic enable
• The front axle mechanical status signal
In order to ensure the electronic shift system is operating properly, the transfer case control module (TCCM) continually performs diagnostics checks on itself and other parts of the electronic shift system when the ignition switch is in the run position. The following are different types of system checks that the TCCM continually performs.
Data Memory Retention Check
The TCCM checks the stored diagnostic trouble code memory to see if the memory has changed since the ignition switch was last positioned to OFF. This self test checks in order to see if the RAM standby power supply has been interrupted. If the TCCM detects a RAM standby power supply interruption, (the loss of stored diagnostic trouble code) the TCCM stores a DTC of 1 indicating RAM standby power failure.
This condition occurs when the TCCM is disconnected from the wiring harness or battery power is removed. The DTC of 1 automatically clears from the TCCM after cycling the ignition switch ON and OFF five times.

Before replacing parts you should test the system !
Diagnostic Trouble Code (DTC) Displaying
The transfer case shift control module is equipped with the ability to store diagnostic information, which is useful to a technician in the event of module, component or wiring failures. This information can be retrieved from the transfer case shift control module by way of flash codes, which are displayed on the three transfer case shift control switch buttons. These buttons are located on the instrument panel to the right of the steering wheel Before obtaining DTCs, perform the following transfer case control module (TCCM) Self-Test.
TCCM Self-Test
Observe the transfer case shift control switch indicators while turning the ignition switch to RUN. A properly operating system will flash all indicators and then will return to the current gear. If the system is operating normally, then proceed to Displaying Codes.
If the TCCM failed the Self-Test, then test the following circuits.
• Battery Positive Voltage (40 and 1640), and Ignition 3 Voltage for battery voltage
• Ground Circuit for ground
• Diagnostic enable circuit for an open or high resistance
• Transfer case shift control switch connector
If the above circuits are normal but the TCCM still fails the Self-Test, replace the TCCM. Refer to Transfer Case Shift Control Module Replacement .
DTC Displaying
Turn OFF the ignition for 10 seconds.
Connect PIN 13 on the data link cable (DLC) to a ground. The DLC is located in the cab under the instrument panel on the driver's side.
Turn ON the ignition, with the engine OFF.
Observe the transfer case shift control switch select buttons for flashing codes. Refer to Diagnostic Trouble Code (DTC) List .
Important: If the transfer case shift control switch buttons all blink only once and then stop, no fault codes are stored in the transfer case shift control module.
• When one DTC is stored in memory, that code will blink that number of times followed by a 3 second pause and then repeat.
• If more than one code is stored, the first code will blink, followed by a 3 second pause and then the second code will blink.
• This sequence will continue until PIN 13 on the DLC is no longer grounded.
• If the TCCM will not communicate the presence or absence of DTCs, test the above circuits in Self-Test Step 2. If the circuits are complete, then replace the TCCM. Refer to Transfer Case Shift Control Module Replacement .

I lent my Celestron 9.25 SCT to a friend and he said he had collimation issues. He said he couldn't find the collimation screws on the secondary so he unseated the retainer ring and pulled the secondary...

Yes because the corrector plate must be replaced in the exact position it was removed. There were probably also small paper or cork "shims" around the glass plate that must also be replaced exactly. Your friend messed up your scope most likely.

YOU DO NOT need to remove the corrector plate to collimate an SCT. The collimation screws are on the center of the plate and accessible from in front of the scope.

There should be 2 sets of adjustments to be done. The first is to sight from the eyepiece holder, and see if the diagonal has the back mirror centered - don't be concerned about the off-center of the main mirror. Once the diagonal is centered, then use the adjuster screws to bring the main mirror into line. Adjust first one way then the next (in or out). When done, your eye should be centered in both mirrors. Then align the finder, and away you go.
