to me it looks like the insulation is deformed and stretched badly.

I think that can basically burst

It should be nice, round, smooth and shiny . There it looks like muscle tissue

It almost makes me hungry for some boneless ribs or something


THe black wire looks kinda funny too, but its too hard to tell from that picture.

i think it is called a redel connector
It seems to be super rare to come by now . Idont know why .
REDEL is a family of connectors from LEMO, which is already somewhat boutique, and the REDEL family seems to be specifically for medical products and the like. The one shown in your image appears to be a custom configuration of REDEL P, since that contact layout doesn’t appear in the REDEL P catalog.

HI everyone.

I went forward with the first solution.
quality of pic not so good i know.

On PIcture 3
[ Attachment Invalid Or Does Not Exist ] [ Attachment Invalid Or Does Not Exist ] [ Attachment Invalid Or Does Not Exist ] [ Attachment Invalid Or Does Not Exist ] Now i found what seems to be an  used wire yellow color coming from the cable. It was clean cut and had nowhere to go to nor any other yellow cable loose to join. Is that something that happens to have wires not used or l should investigate what the yellow color is supposed to controle and keep an eye on the task or at least be aware.?

It there a way to use a multimeter to test if it has current going inside itself?

I found some black heat shrink a bit kind of thick and added 1 inch and then anoter 2.5 inches . It goes over the gromet kind of nicely . For now that is the solution even though i ordered a new gromet in case i have to reopen the thing, hopefully not.

Could you please edit your reply to remove the inline image tags? (Which will cause them to revert to end-of-post attachments.) When inline, they do not scale to screen size, meaning that on non-gigantic screens, when inserting huge images like yours, one must scroll back and forth to see the whole image.

(I normally browse on my iPad Pro — a larger than full HD display — and the attached screenshot shows what your post looks like.)

You did the opposite of what was needed: you deleted the attachments, but left the tags in the text. You needed to delete the tags, but leave the attachments. Now the images are gone entirely.

The default setting “end-of-post expandable thumbnail” is what you want 99% of the time. It gives the result shown in my post with the screenshot.

Hi what do you mean by tag?

i tried pasting them back this time with end of post mention  instead of inline.
How is that?
They look as big as the first time to me.

Hi I am surprised not to see any reply . Is it because of my poor english of management of the pictures?
I will try something that might solve the situtation: I will modify the picture way with 4 or 5 different attachement and hopefully someone will tell me wich one of the attachement way  works best for seing you without having to figgle fart with the scolling left and right up and down and once i will know the prefered method i will apply it to the 4 pictures i want to show you?

 Is that a reasonable approch? Sorry, I am not very computer oriented, i try my best

Hello Repairs,

Looks like a good job! Don't forget the zip tie. Pull the zip fairly hard. It is the one thing that keeps the cable from slipping out. I'd even put 2 zips  :D

After thoroughly checking all your pictures I too have the impression that the yellow wire is unused and was never connected.
- Given its length, I think it was cut off near the entrance on purpose. That is not just a coincidence.
- The wires of the cable you repaired disappear under the board with the components. Could you check their routing? My thinking here is that every wire consistently has a connector fitted. If the yellow wire was detached from somewhere then you would find a spot that still has the metal part fitted in the connector but is missing a wire. I cannot find any in your pictures. There is that completely empty spot in the connector with the lonely green wire, but it has no metal part in it and is not the right size for the wire, so the wire was not connected in that spot.
- You would also have found another piece of yellow wire somewhere as currently it is not long enough to be connected.
- With a multimeter you could check if that yellow wire is terminated on the Redel connector on the other side. But even if it is, and I think it will as your picture shows 6 positions, it does not give the information if it is in use or not. To check this, the easiest method is to use the continuity mode on the multimeter, the one that beeps. If that mode does not exist then select resistance and look for very low resistance, use another wire for a reference measurement to understand what to look for.

When it fits stop using the hammer

Yes, it looks like a good practical repair.  :-+

Sorry, I only got a quick look at the large photos before you deleted them, so I didn't really get to examine them in enough detail to give a sensible reply.

As Swake says, don't forget at least one cable tie to resist the cable being forcibly pulled out. It's really good that you've found that you can get adhesive lined heatshrink to fit over the connector at the far end. That should give you as much bend protection as a new grommet - probably more. Be sure to keep some available and replace it at the first sign of damage. 3:1 shrink ratio, adhesive lined, is common but I think I've seen 4:1 too.

Regarding the yellow wire. Judging length by eye, yes I think you are right that it was cut off flush with the original outer insulation of the cable, fairly common practice for unused cores. If everything is working correctly, I would just fold it back on itself and put a piece of sleeve or tape on it to avoid any possibility of shorts (to the metal joystick can for instance). That's assuming that it isn't also cut off at the plug end - better safe than sorry.

You've probably saved yourself quite a lot of money there. My neighbor managed to get a replacement joystick unit on ebay, but then had the problem of programming / configuring it to work with his chair. Irrc, it needed configuring for the options on the chair (lift, moving footrest etc) and things like acceleration. He was responsible for finding the bootleg configuration software etc. - my only involvement was implementing a non-standard USB-serial PC interface, but it certainly wasn't plug-and-play.

I'm glad you're back in business anyway. Try to be a bit more gentle with it - although I realize that it probably gets daily wear and tear. Maybe you can rig up something (even a bit of velcro) to avoid it getting dropped as much. Good luck with it.

Hi this is the multimeter i have . can it do it? I dont know continuity mode and feel lost on how to do what.

Yes I did put 2 tie wrap plus glue.

Yes, your multimeter has the beeper mode. Turn the knob just past the 'V--' position, and before the 'Hz'. See attached pic for position.
That position has 4 modes, you want the one with the 'sound waves' icon. I believe you might have to press the 'select' button, eventually multiple times. The same 'sound wave' sign should show up on the display.

In that position the multimeter will beep when you short the 2 measurement leads together. And that is exactly how you want to use it: put a test lead on each side of the wire to check if there is connection. If it beeps there is connection.
When it fits stop using the hammer

Ok thanks for the info.
I put one end on the yellow and the other on the 6 different pin of the connector? That would tell me if the cable is broken inside ?

How to know if it has a use? just by putting only  one electrode on the end of the yellow wire and put the joystick on move the chair and see if there is a signal?

Noooo!

If all functions of the chair are working correctly, don't connect the yellow wire to anything - you will probably blow something!

In all probability, given its original length and lack of any snapped end inside the joystick, it was never connected. Measuring continuity to what? What will it tell you? Nothing that I can see.

I am worried that you are taking the joystick apart more than you need to. This is stressing the connections between the upper and lower PCBs, if you break one of the fine connectors it will be beyond your ability to fix.

If everything is working as it should (and already you have the case open) put some insulating tape on the end of the yellow wire and put it back together for good.

Hi repairs,

Sorry if I sounded panicked but I've seen people fix things, then push it one step further and break them in bad ways before - I've done it myself (several times!).

Don't worry about the thread, it will never get deleted or closed so you can come back to it at any time. The only ones that get deleted are spam and similar, even when thread discussions get 'nasty' the Mods prefer to lock them rather than delete. The forum search feature is pretty poor, so it is easiest to find an old thread is by looking at your own profile - show posts -> messages or topics... https://www.eevblog.com/forum/profile/?area=showposts;u=1036387.

I'm glad we could help you get up and running again. Do hang around, or at least log in occasionally.

Best wishes!
Best Regards, Chris
