You will need a socket called an RJ45 (8P8C), which has 8 contacts. Many are available as telephone line (three phone line) extension connectors. This is also like an ethernet Cat5 or Cat6 (8 wire) computer network cable connector You can get these at Radio Shack or Staples or similar office supply. You can take apart the $5-9 connector and use half. Either that, or you will have to go shopping at an electronics store like Fry's or on line (Allied, Digitech or Mouser). But there you may have a minimum order charge.
But are you sure it is the socket and not the cable? Can you swap the cable end for end or buy a new one?
"Recently there have been complaints about declination drive intermittent electrical problems. Many do not realize that there is a second plug on the inside of the fork where the declination cable plugs in. This plug should also be worked from time to time as well and cleaned." from MAPUG

I have an older meade LX2000 EMC 10


The main problems encountered with the mechanics of the telescope centre around the mechanical swarf, grease compound, the liberal use of grease and the quality of machining of the main DEC and RA gears.
1. Remove the motors from the telescope. Be careful when removing either motor as there is a compression spring between the motor mounting frame and the worm shaft assembly.
The RA motor is located under the telescope body, removing the 4 screws and 2 Allen bolts will allow the bottom cover to be removed, thereby allowing access the the 2 Allen bolts holding the motor in place. Unplug the motor from the main PCB before removal.
The DEC motor is in the the fork arm containing the clutch and fine DEC adjustment control. (Never to be used with power applied to the scope). Remove the 3 small Allen screws holding the plastic cover plate in place and the DEC clutch knob to allow access to the motor. Remove the RJ45 connector located inside the telescope fork arm. Then remove the motor by unscrewing the 2 Allen bolts holding the motor in place.
2. Remove all grease from the motor worms, especially around the RA motor's magnetic pulse detector and the permanent magnet built into the worm shaft.
3. Remove all grease from the main DEC and RA gears, making sure to clean into the gear teeth.
4. Lightly re-grease with a Molybdenum Disulphide based grease (Castrol MS3 is great for this application if you can get it)
5. Assemble in reverse order. But before doing so, carry out the electrical adjustment above then, (a) relocate the the RA and DEC control PCB's in the vertical plane thereby gaining access to their respective backlash Allen screws. Adjust for 20thou max clearance when in final position. Note:- the DEC adjustment screw has to be replaced for a longer unit complete with a thin bolthead as this adjustment has to be carried out with a spanner....there is no room for an Allen key adjustment here.
6. A drop of Loctite must be applied after adjustment.
7. The final part of the process is to run in the gearing. Apply 12 volts to the motor wires, either at their respective plugs or to the motor direct. Allow to run for 2 to 3 hours in each direction by reversing the battery polarity to bed the teeth engagement. Remember to release the clutches.

Replacing spark plugs and coils on Mazda Tribute V6


Here are DIY step by step instructions for replacing the spark plugs and / or coils in a Mazda Tribute V6 (based on a 2001 Tribute).

This is a lengthy procedure, but don't be frightened, it works...I have done it a few times. This will save you a few hundred $$$ if you do it yourself. Make sure to read all of these instructions, preferably while looking at your engine, before you get started. You will need 2-3 hours to do this job.

NOTE 1: IF YOU HAVE A SPECIFIC ISSUE WITH CYLINDERS/COILS 4, 5, OR 6, YOU ARE IN LUCK, YOU ONLY HAVE TO REMOVE A PLASTIC ENGINE COVER. IF YOUR ISSUE IS WITH CYLINDERS/COILS 1, 2 OR 3, OR YOU ARE CHANGING ALL OF THE SPARK PLUGS, YOU WILL HAVE TO REMOVE THE INTAKE MANIFOLD. THESE INSTRUCTIONS COVER CHANGING ALL OF THE SPARK PLUGS AND CAN BE USED TO REPLACE ANY OF THE COILS.

NOTE 2: IF YOU ARE THINKING OF REPLACING YOUR SPARKPLUGS BECAUSE YOUR ENGINE IS RUNNING ROUGH, PLEASE DO YOURSELF A FAVOR AND GET THE ENGINE SCANNED FIRST TO MAKE SURE THAT A COIL IS NOT THE ISSUE. YOU CAN REPLACE YOUR PLUGS AND BAD COILS AT THE SAME TIME WITH THIS PROCEDURE. YOU WILL BE UPSET IF YOU DO THIS WORK TO REPLACE ONLY YOUR SPARKPLUGS, THEN YOU FIND OUT AFTERWARDS THAT A COIL WAS BAD AND YOU HAVE TO DO IT AGAIN LIKE I DID.

1. Tools: Pliers, ratchet wrench, ratchet wrench socket extension, 8 mm socket, 10 mm socket, Spark plug socket, flat head screw driver, plastic zip tie, plastic cup or bowl. Not necessary, but very helpful: Magnet on an antenna to pick up dropped nuts/bolts.

2. All directions are given from a point of reference as if standing in front of the car, except for removing the coils and plugs from firewall (back) side of the engine.

3. Using flat head screwdriver, loosen band clamp on large rubber air intake hose where it connects to the intake manifold on the right side of the engine. Slowly work rubber intake hose off of intake manifold.

4. Unplug wires from back side of air idler valve - small unpainted metal part mounted on top of air intake on manifold (close to where the air intake hose connects to intake manifold).

5. Disconnect small rubber hose from top of the ERG valve (black metal disk near back right side of manifold.

6. Remove the two bolts that hold ERG valve to manifold bracket. Use the 10 mm socket and ratchet to remove these. If you are trying to remove the 8 mm bolts, you are removing the wrong bracket. Be careful, there is a gasket between the manifold and the ERG valve, make sure it does not fall out when removing bolts. Place bolts and gasket in cup.

7. There is a small plastic sensor just to the left of the ERG valve towards the back of the engine. If you look at how the sensor is attached to the manifold, you will see that the back left side bolt that holds this sensor, also connects the intake manifold to a plastic wiring harness at the firewall. You will need to remove the 8 mm nut from this bolt to free up the intake manifold in a later step. Now remove 8 mm bolt from other side of sensor. Might need the socket extension to remove these. Place nut and bolt in cup.

8. Unplug wires from the back of the sensor discussed in the previous step (7).

9. There are 3 hoses of different sizes plugged into the back of the manifold. Unplug all three hoses from manifold. Remove zip ties if needed to slide hoses off. Left hose may have a compression clamp, use pliers to loosen clamp while sliding hose off.

10 There are two large black plastic wiring connectors supported by the back left side of the manifold. They are supported by plastic clips with plastic barbs. Use the flat head screw driver to pry off the support clips from the manifold - don't worry, you won't break them. You will be able to plug them back in later.

11. There are still a few things attached to the intake manifold, but there will be enough flexibility now to lift up the manifold and replace the spark plugs.

12. Remove the plastic engine cover - there are three 8 mm nuts to remove. You will need the socket extension. One the nuts are removed, you will have to wiggle the cover off especially on right side. Place nuts in cup.

13. The plastic intake manifold on top of the engine is now exposed. If you look down at the front side of the engine, you will see the coils for cylinders 4, 5 and 6 (going from left to right). The tops of the coils will probably say "Motorcraft" on them. Also, there are two cables attached to the top of the manifold - leave them alone.

14. There are 8 bolts that hold the intake manifold down. The bolts are located in two rows of 4 across the top of the manifold. Loosen them all using the 8 mm socket with extension. Note: these bolts do not come completely out when fully loosened.

15. Slowly work the intake manifold loose by lifting up on each side. NOTE: Work the manifold off of the bolt discussed in step 7 (back right side of manifold), NOTE: Work slowly watching for anything that might be hanging up. You should eventually be able to get about 4" of clearance between the back right side of the manifold and engine, and 8-10" of clearance on the back left side. Move around to the passenger side to help lift off the manifold. While working on the back side plugs, you will stand on the passenger side of the car.

16. Once you are able to lift up the manifold, get a cup, block of wood, anything suitable approx. 5" tall to prop up the manifold (place under center of manifold). This will keep the manifold off your hands while you are working.

17. The three coils on the back side of the engine are now visible if you are standing on the passenger side of the car (cylinders 1, 2 and 3) Cylinder 1 is closest to you - passenger side, cylinder 3 is furthest from you - driver side.

18. Each coil has one 8 mm bolt holding it down. Take the 8 mm socket and ratchet and remove the bolts from the 3 coils on the back side of the engine. Place bolts in cup.

19. Lift each coil away from engine (do not pull on wires plugged into the coil). Pull each coil's silicon rubber tube out of spark plug hole, bend tube to get it out without pulling on the coil wiring. Leave coils plugged in and lay them to the side. NOTE: If you are looking to replace a coil (or coils) simply unplug the coil wires from the old coil, and plug into new coil at this stage.

20. Using sparkplug socket and socket extension, remove each of the back 3 spark plugs.

21. Install the new spark plugs (gap them first if they are gap type).

22. Slide each coil rubber tube back into sparkplug hole and bolt down coil (8 mm bolt). Congratulations! The hard part is over with!

23. Make sure the rectangular intake port gaskets are clean on the engine (before lowering the intake manifold back down).

24. Slowly work the intake manifold back down to the top of the engine - make sure that the manifold is back on the bold discussed in step 7, and that nothing is binding.

25. Bolt the manifold back down (eight bolts, 8 mm, still attached to the manifold). Use 8 mm socket with extension. Gradually tighten the bolts going from bolt to bolt until they are all tight (don't fully tighten one bolt first).

26. Remove coils and spark plugs on front side of engine. Replace spark plugs and re-install coils. Same procedure as back side of engine, but much easier. Replace coil(s) if desired.

27. Re-install the two plastic wiring connector support clips to the left side of the manifold - push barbed clips into manifold.

28. Reconnect 3 hoses to back side of manifold. Place new plastic zip tie on hose that had zip tie.

29. Reinstall plastic sensor on back right side of manifold (8 mm nut and 8 mm bolt).

30. Plug in wires back into back side of plastic sensor.

31. Reinstall 10 mm bolts and gasket on ERG valve and tighten to manifold.

32. Reconnect small rubber hose to top of ERG valve.

33. Reconnect large air intake hose to intake manifold and tighten hose clamp using flathead screwdriver.

34. Plug wires back into back of idle air control valve (this was uplugged in step 4).

35. Leave the plastic engine cover off for now. Check all around the manifold and make sure everything is reconnected.

36. Start engine - should start and run normally (or better). If not, go to trouble shooting at the end.

37. Reinstall plastic engine cover (three 8 mm nuts). Make sure engine is not running when reinstalling plastic cover.

TROUBLE SHOOTING: If engine light comes on (and wasn't on before changing plugs), or if engine runs rough, stop engine and double check that all wires and hoses are plugged back in. If you find wires or hose left disconnected, reconnect them. Disconnect car battery for a few minutes then reconnect (to clear out engine alarm). Restart car, engine should run well, engine light should be cleared.

How do I replace the back iginition coils for a 1999 acura tl?


You need to remove the bolt on each coil. Mine was a 6mm allen bolt. Then carefully remove the wires plugged on to each coil. Mine had a small button on the side of the plug/clip that I had to press in to pull the plug off. Then the each coil should slide right out. Slide the new coil in. Reconnect the wires to the coil and put the bolt back in. Done. Quite easy. Just takes a little patients because there is only so much room behind the motor.

What tools do i need to replace windshield wiper motor and where is the location on a 2000 gran prix


You'll need a socket and ratchet set. Being Pontiac, probably metric(12 or 13 mm). Go to the auto parts store and get the new motor. Now open the hood, and look all the way in the back of the engine to the firewall, around the drivers side. Just undo the bolts with the ratchet and socket. pop loose the control arm and undo the wiring. To replace, take the new motor, hook to the arm, bolt into place, attach the wires, and your in business. About 30 minutes to do for a beginner.

HOW TO REPLACE SPARK PLUGS


    Follow this steps on how to replace the spark plugs,

    1. Locate your spark plugs before beginning. Accessing the spark plugs can vary greatly depending on the model of motorcycle. The Ninja series bikes place the spark plugs near the top of the motor, hidden beneath the fuel tank and air box.

    2. Remove the seat and fuel tank. Locate the bolts that secure the fuel tank to the frame and remove them with a socket wrench. Lift the fuel tank upwards and disconnect the fuel lines. Pull the entire tank away from the motorcycle and set it aside.

  • 3. Unscrew the air box lid with a screwdriver and remove. Remove the air filter and locate the bolts that secure the air box to the motor. Unscrew the bolts with a screwdriver and pull the air box off of the motor. Take note of the locations of any wiring or hoses that may be attached to the air box before disconnecting them.

    4. Pull the spark plug wire off of the first spark plug and clear the plug cavity with compressed air to remove dirt or debris that may been trapped. Remove the spark plug with a spark-plug socket. If needed, use a socket extension to reach the spark plug in the cavity.

    5. Insert a new spark plug into the cavity and carefully tighten with a spark plug socket. Slide the spark plug wire onto the end of the spark plug and press down until the wire clicks into place.

    6. Repeat as necessary for any remaining spark plugs. Reinstall the air box and reconnect any hoses or wiring removed earlier. Insert the air filter into the air box and seal the lid by tightening its bolts with a screwdriver

    7. Reinstall the fuel tank, reconnecting the fuel lines and tightening the mounting bolts with a socket wrench. Replace the seat.

How do I change the windsheild wiper arms?


Hi,
Open the cap at the end of the windshield wiper arm at the cowl of the Blazer. This will reveal the bolt that secures the wiper arm to the wiper linkage. Unbolt the wiper arm using a 3/8-inch ratchet and socket. Place the bolt to the side, as you will reuse it later. Pull the wiper arm up at the blade so that the blade of the wiper is pointing into the air. Then pull at the base of the arm, wiggling it slightly. It's a keyed gear, so it may take a little bit of work to break it free, but with the right amount of wiggling, it will disengage. Then you can replace the new windsheild wiper arms to it.

Thank you !!

I need to install a new ignition coil in my 1998 ford windstar. How do i do this?


Hi,
You can sometimes (if you have 2 elbows on each arm) reach around the back of the intake manifold and replace the coil pack using a 1/4 inch rachet with a 7mm socket.
Most of the time you need to remove the plastic cowl assembly located under the windshield wipers. To do this remove both wiper arms by lifting the plastic covers at the bottom of each wiper arm. Remove the 15mm nuts that hold the wiper arms down and wiggle the arms while pulling upwards until they come off (take note of which is left and right, they are different sizes). Next remove the plastic phillips screws/ plastic rivets that hold the cowl down on the bottom towards the engine(the screw comes up half way and when you pull up the base/ rivet comes up with it).
Next pull up on the cowl where it meets the windshield left or right side and you will hear the retainers snap and release. Continue pulling until the cowl is loose. Next disconnect the hoses that go to the washer nozzles. Put the cowl aside.
Next remove the micron filter located on the passengers side of the cowl (if it has one it is a good time to replace it). Remove from left to right 8or 9 8mm bolts that hold the lower cowl down. On the drivers side disconnect the 8 pin connector for the wiper motor. Now disconnect the washer fluid hose that goes thru the cowl on the passengers side. Lift up on the cowl and you should be able to wiggle it out and set it aside. You can now see the coil pack behind the intake manifold. Take note of spark plug wire location on the coil pack because they have to go back on in the same order.. Reassemble in reverse order. Note that while the cowl is off it is a great time to replace the spark plugs on the back of the engine.
Good luck to you and congratulations for doing it yourself

Bolt holding dec drive motor on 16 loosens.


You have a LARGE Meade telescope. This should be an easy fix if you can disassemble the fork arm and get inside.

First I would contact Meade customer service to see if they have a manual that shows disassemble instructions. If not I would join the Yahoo LX200 forum and look for help there with an owner of the 16 inch model.

http://www.meade.com/support/index.html

Just search in Yahoo Groups for the LX200 forum.

On smaller scopes the DEC motor is held on by two spring loaded bolts, probably one has become loose?

Blower motor location for 2000 Caravan


The motor is located just under the glove box on the passenger side. I remove the glove box then the panel below the glove box. I also go ahead and pull back the carpet and the padding under the motor. It is held in place by 3-4 bolts that take a 7-8 millimeter socket. I use a swivel extension for the back bolts. The motor with the fan blade attached is a tight fit, just keep wiggling and pulling it should come out. Try to remove the old moter without cracking the fan blade, because sometimes the replacement motor doesn't come with a blade
