TID 29r-10

Does anyone have a picture that clearly shows which wires goes to which pins? The wiring diagram is pretty vague about it. Thanks for your help.

 

What model uses the TID14-21 29r-10?

 

My bike does! 1983 XJ750E-II, frame numbers starting 29R000xxx, engine "number" simply 29R


Pretty uncommon bike if you have a real one 8)

Where are you, got any spare carbs?

 

I have an xj650g and currently rebuilding it. After rewiring it I noticed the TCI obviously was the wrong one. I was curious as to how the previous owner wired my bike to use this TCI. Mine calls for a 4H7 not a 29R.

 

AFAIK the TCI from any XJ will plug straight in and "work" with the same pinouts, but obviously the timing/advance curve will be out with the wrong one.

Provided the TCI you have is not broken, you should be able to get the bike at least started with it for testing, but I would recommend locating a correct unit before riding anywhere.

This is based on info from reading other posts searching the forums, where people put their TCI into another, running, model to find out if it was working, so don't take it as read that I'm correct on the interchangeability side until another more experienced member in this field has confirmed/squashed that statement

 

It has been said recently on another thread that an XJ would run with the wrong TCI, but poorly and roughly.

 

I have chopped out my bike and eliminated the safety string. I'm concerned that the 29r TCI needs this in order to work. The 29R has only 3 pins in the 4 pin slot where mine uses all 4 pins. The 29r has 6 pins in the 6 pin slot where mine only uses 4.
I'm not sure how the previous owner wired it up. I went to a basic wiring system for the xj series. Unfortunately I'm sort of lost now.

 

750E-II_29Rbloke- I take it you're in the UK where I myself am in the Philippines. If I happen to run across the correct TCI for my bike. (not running out and buying one), and since you were good enough to answer my post, I'll just give you this TCI for a spare.
Thanks for your input.

 

I don't blame you not running out buying one, heard they fetch about $100 in the states (yes I'm in UK by the way.)

Seems to me maybe your best option would be to trade the TCI you have for a correct one rather than giving it away for a few minutes of typing but thank you very much for the offer 8)

I can't recall if anyone currently has a correct TCI for your bike up in the for sale/wanted area but I guess you could have a look & maybe post a swap/trade advert in there for the one you have?

If I can find any wiring diagrams for my bike I'll get back to you on the pins for the 29R TCI

EDIT-: oh, and if you have a wiring diagram for your bike online and you email it to me along with maybe a couple of photos of your wiring plugs, one from the pin end of the plugs another from the wire end (email button in my profile) I can try to have a look & see if I can work out if anythings changed

 

Thank you I will do that

 

xj650g wiring diagram

 

Right, just before I go to bed, although that diagram's not the clearest it seems to show the TCI box having total 8 wires, 4 in each plug.

one plug (4 wires) deals with the signal from the pickups (behind the cover on the left end of the crank). The other plug (other 4 wires) deals with firstly the positive feed from the battery, then a switched earth for each coil, and I *presume* but don't quote me, a switched earth for the TCI itself running from the kill switch etc though the safety circuits if any.

That being the case, try to find which plug is the one dealing with power and coils. (I think *again not 100%) that the coil switched earths are orange and grey?

We need to find which wire is missing from your circuit then we may at least get you a spark with the 29R box ready for fitting a correct one 8)

There's a couple of things for you to check there and we can go further A) when I've had a chance to sleep & have a look at another wiring diagram B) when someone can confirm/deny that the coil side wiring plug should have 4 wires or not.

Hope I'm not being too obscure in my descriptions, oftentimes I know what I mean in my head but it comes out greek to anyone else!

Goodnight for the moment, will get back to you tomorrow

 

Thanks for your help. Good night

 

Good timing, I'm up again and just had a quick look at my TCI and plugs.

Can't find my multimeter (sods law) but from looking, the front, smaller plug has 3 wires in it, from the end the wires go in they are top left orange, bottom left grey, bottom right empty, top right black)

The other plug has 5 wires, (well 6 but 2 are in the top left pin and are red/white stripe), top middle orange, top right blank, bottom left black, bottom middle grey, bottom right black/grey stripe


Will try make a clearer picture for you. Could you check and report back what wires you have, maybe use MS paint or something to make similar picture as I'll make.

 

If you can do a similar drawing of your wiring plugs showing what wires you have where from the same angle as I've drawn this that would help, thanks 8) I think maybe the p/o crossed a wire from the right plug to the left but need to see your setup to confirm




I believe from some looking round that the 3 wire plug should be the grey and orange wires to the coils, and the black is the TCI earth.

The 5 wire one should be the orange, grey, black & black/grey from the pickups on the crank, then the last one should be the TCI/coils live feed which is the 2 red/white,

one needs to run to the coils for their live feed. the other should go back through the loom, originally This would go through the safety circuit but I believe if the safety circuit has been removed you could wire it so it comes live when the ignition & kill switch are on.

On my TCI the left plug has 3 pins, but on the right it has a pin in the vacant slot, I *think* this is related to the rev limiter built into some GAUGE CLUSTERS which uses a yellow or yellow/black wire. Obviously not every bike has this & isn't essential to run.

 

Good morning/afternoon.

 

The black/grey must be an inductive ground.

 

That's right, the 6/5 wire plug's black and black grey are effectively the ground for the pickups which are inductive.

Only the black in the 3 wire plug should be a frame/battery ground

Was the black grey the one that got switched in your loom? (what colour wires do you have in the 4 pin plug?)

 

Sorry it took so long to reply. I actually had to do some work today...arghhhh!
I wasn't able to make the drawing that you wanted. I need to find out how the correct TCI is wired.

 

Don't worry about it, I couldn't get online last night anyway :cry:

Is there any way you can get the wiring diagram clearer on here?

What I'm saying is, if TCIs are interchangeable (apart from the timing curve being off) then the wiring should by rights be the same.

 

OK I've had a look over some wiring diagrams and NOT all TCI's have the same configuration so the 29R TCI shouldn't work with your wiring unless the p/o has changed it. Along with your minimal wiring I'd need some more info to get you running.

I need your

Engine number

Wiring loom number from sticker under tank if it's still present, if not I need you to make a picture like mine with showing wire positions/colours

This way I can be more happy about what loom we have fitted, if you can get all the details above I'll compare to my wiring diagrams now I've found them

If you're ok with a multimeter then as well as that you could (with TCI unhooked, battery fitted, ignition on, killswitch set to RUN, neutral light on) take a voltage reading from your red/white wire to battery negative, (should get power) and continuity reading from the 2 black wires plus the black/grey to earth too and indicate your readings on the picture.

We'll work from there, can't really advise further without knowing exactly what wiring you have & where your power & earths are but we'll get there if you supply the info :lol:
