TCI Numbers

Hi,
I'm looking for an idea on the part numbers on the front of the TCI.
I recently purchased a few bits and pieces on ebay, since they were going so cheap and... well just because I figured one day I'll get that second bike running and 99cents is a bargain for a regulator(with a TCI unit on the same plate!)

Anyway...
The question is I can see different part numbers on the stickers for 2 of the TCI units (the third 99cent job has no cover) and was wondering if someone could give me a clearer idea of whether they are matched to plug coils/pickup coils or something else fundamental like cam lobe size/degree etc.

Here are the two numbers I have, one that came with the bike and one that I bought and the description of the bikes they came from.

XJ750P 85(mine) TID14-02 4H7-10 (012)
XJ750P 86(ebay) TID14-06 5G2-10 (005)
XJ750 81(ebay) no cover

Now in my haste I plugged in the unit without the cover to see if it would work and it did... but it was only when I plugged in the other ebay unit with the different numbers that I realised the numbers were different! (although I started the bike and it ran the same also, before I looked closer at the plate and began to worry about the rest of the electrical system).

I only plugged these in after the bike was warm and only tested them for about 20 seconds a piece at idle with a few blips of the throttle.

So if anyone can shed a bit of light on the numbers I'd appreciate it.
Thanks guys!

 

I checked mine and it's th same as your 86(ebay) one except th last three numbers in brackets, ie. th little box with th stamped in numbers. I have a spare from a parts bike same year and month as mine and it's also th same except last three numbers, 'spose those 3 were something to do with it's assembly.
So far as I know you can use different TCI units that will run th engine but not as good as th right one..dwell, cam timing etc...
edit.... Just did some looking on Chacals model codes list.. I reckon you're running a 650 TCI....4H7 corresponds to '81 650. 5GT corresponds to '81 and later years 750. So maybe th 86 (ebay)is what you should plug in...??

 

Aha! I see what you mean with the letters matching the bike VIN codes.
Thanks for pointing it out.

Wow I wonder what difference swapping over to the 5G2 will make. Obviously I envision gaining an extra 100cc of POWER!

 

The 5G2-10 (TID14-06) unit is the correct one for a 750P (37H) model engine. The three little numbers stamped in the small "chrome" rectangle is a production date code, I believe.

The 4H7-10 and the 5G2-10 units are almost the same. The 4H7 version does not have the 5th terminal pin to recognize the kickstand relay safety switch circuit.

 

That's interesting.

Will the TID14-06(5G2-10) cut out if the sidestand is down?

At the moment the stand light will come on if I leave the bike running and put it on the sidestand with the TID14-02(4H7-10)...

I'll have to investigate further!

Do you think there is a way to identify the coverless TCI? or are they all pretty much the same timing wise?

 

Yes, it should. That terminal is a grounding path for the TCI that gets opened up by the sidestand switch relay.

Correct. The dash gets the signal from the sidestand switch and relay, but since there is no grounding path for the TCI, the TCI keeps on a-truckin'......

Paging Dr. Robert, Paging Dr. Robert.........but a partial answer is: no, they are not all the same timing-wise, that's the "other" major difference between the various versions.

 

Since I've seen my sidestand light come on at least a couple of times while going for a spin I'm thinking I'll stick to the 4H7 and keep the 5G2 as the backup and keep the coverless as the backup, backup... since I can't bring myself to throw anything from my XJ out (which may become a real problem soon).
I did throw away the 1998 newspaper that was in the last box of bits you sent me the other day though! Okay... I kept the box though

 

Quote:: I've seen my sidestand light come on at least a couple of times while going for a spin I'm thinking I'll stick to the 4H7..

.. jst wondrin why having th sidestand light come on while riding is a good thing? I assume it's not down. If it's not down th switch probly needs cleaning / lubricating?

 

Wow! Here I thought it was for the electronic tach output... I'm pulling out my schematics again... I am suffering with a, a, a puzzlement. I've seen the 5G on all the models that utilize the electronic tach but I never drew the connection to the side stand relay (starter cutout circuit).
I don't have any spare covers, sorry. I could give you a 4H7 or 5G2 i.d. off of the circuit board layout but that is as close as I could get you.

 

The TCI IC Ignitor numbers should match the numbers that are stamped on the reluctor underneath the pickup coil cover...see attached photos

 

Nope, the electric tach signal gets taken off of the gray wire from the (always) 4-terminal side of the TCI box....the "output" side of the TCI which also goes to the ignition coils.....it's the other, larger "input" side (that can hold up to six terminals, although only 4 or 5 are ever used) where the presence of a black wire with a white tracer stripe indicates the use of the kickstand switch relay lead wire......

 

I did clean and lubricate the switch when I originally stripped the bike to repair the crack at the sidestand mount and although it could be the switch I'm thinking it may also be the connector to the dash that I still have to replace.

The 9way(8pins) connector is in a bad way, corroded contacts and cracked plastic shell with 3 sides missing, but I haven't found an appropriate connector replacement for that one yet.

I've been keeping my eye out for shower proof connector replacements, no luck so far though.

Another thing on the todo list, which keeps growing somehow.

Sounds like a plan, I'll pull it apart to clean up the joints and post some macro pics of both sides, thanks.

Now that's a nice simple way to match the TCI to the bike. Good one!

Nice!
I thought i'd do a rummage through your price-list and do all the connectors but I can't seem to track down the connector blocks or that part number...?

Any chance you can do a kit (or dare I say, already do a kit?) to replace all the dash connectors?
That would be great. Thanks.

 

fiveofakind...took th cover off and had a look at th reluctor..5G2-10, same as th TCI. Great bit of info' for th topic, don't recall seeing that before.

 

Apologies for the mountain of pics, in advance...

Here are some close up pics from the removed TCI board, hopefully Robert can do the magic ID!






and that reluctor-TCI match tip is great... mine definitely do not match!

 

Looks like the one from my 82 SECA 550.

Of course, I can't tell if there are any differences in the laser trimmed hybrid sub-board, but I can verify that the rest of the circuit and board is identical.

 

Hi,
Seca 550! I was told it was from a 750 81 but.. Just a couple of questions.

Does the sub-board number match HSA-005?
and Is the number to the right of the power diode(just above the IC) match the GD203027 on mine?

I just couldn't make it out with the reflection in your pic.
Thanks.

 

I can confirm that the main PCB is identical, including all the visible components and the "GD203027" and "HSA-05" markings.

However, I unfortunately do not have a pic showing the other side (the normally visible side) of the sub-board, so I cannot confirm the existence of the "HSA-05A" on the sub-board itself, but my strong suspicion would be that it does in order to match the main board.

One of the things on my long to-do list is to take the ignitor assy apart again, and when I do, I'll be sure to take some pics of the other side.

 

Howdy folks,
I've seen this TCI layout on 82-83 750 Secas and Maxims.
The HSA-05A board shows up on them as well as my 400 TCI. If it runs, be happy! And change the capacitors at your convenience.
CDS1984, I've shamelessly grabbed your photos for inclusion in my library of TCI photos. I hope you don't mind.

 

Cool! It's looking pretty universal so far.
Glad there was some sun out on the day... you just can't beat sunlight for macro pics.
One extra question while were talking about re-furbishing, what do you find is good for removing the varnish?
Thanks again for the info.

 

Damn nice thread!
Havn't had my attention caught like this in a long time!

Thanks to everyone for a great lesson.

 

So it seems they use the same board on a bunch of different displacements. Wouldn't be surprised if they have different ignition timing advance curves though.

I suspect the laser trimmed resistors on the sub-board are what is used to characterize the timing curves. That way they can use the exact same board assy and trim it in production. You can see the laser trimming in some of the pics:

Help!!! 8O 8O 8O

 

On the white ceramic sub-board, you see the black rectangles? That is resistive material that is silk screened onto the ceramic substrate and then cured. Notice how they always span at least two of the silver traces? In circuit, they are resistors.

Now if you look carefully at some of the resistors, you can see a line that starts at one end and proceeds from there towards and often past the middle of the resistor. That line is a burn mark from a laser which is used to cut through the resistive material leaving a thinner, and hence, higher value resistor.

They measure the resistance as they burn away the resistive material and stop when the resistance is where they need it to be.

Obviously, you can go up, but you cannot come down.

 

I use technical grade alcohol to clean the conformal coating off (I think it is pretty cheap polyurethane). Daub it on, wait a few seconds and agitate it off with an acid brush.

 

Robert, What type of alcohol do you use?

I use 90% isopropyl as flux remover and it works great, but when I tried it on the conformal coating, it didn't do anything. Maybe dulled the finish, but that's about it.

I finally resorted to acetone which dissolved the coating almost instantly, but dissolved some of the component markings just as quickly.

 

The comment I made earlier was an observation I noticed......

That the TCI Ignitor number stamping & the plate & reluctor underneath the pickup coil cover match.......does that hold true for all of these bikes ???

That the numbers should match, then one knows whether they have the correct TCI Ignitor matched for their bike ???

 

I'm using the stuff I buy in the gallon can at Home Despot.

 

This statement holds true for about 90% of the XJ series coils/TCI's. Some of the 700 and later 900 units don't/may not follow this rule.....

 

That's usually ethyl alcohol denatured with methyl or straight-up methyl.

I didn't have any of that when I was working on the TCI's last time, but I have some now from a different job. Thanks for the tip... I'll give that a try when I'm back into the next ignitor. :idea:

 

Must be this one

 

found it yamha vision tci rebuild very good link

 

Whether or not that was deliberate or a typo, that made me laugh :lol: Surprised nobody else noticed it.

EDIT-: woops, bit of an old post... :?
