Has anyone ever found an aftermarket TCI black box? I have seen a few threads about soldering new diodes but nothing with any real information about components or any schematics.

I would love to repair mine but need a schematic to troubleshoot. The closest I can find is the normal wiring diagram from service manuals.

Alternatively is there anyone out there making plug and play ignition boxes? I found this one Italian company that sells something.

Has anyone had any experience with this unit or another similar?

I have used Pamco ignitions before but want to also explore my crank mounted ignition options.
 
$300 for it is kind of ridiculous. What are the symptoms of your TCI failure? If possible check it with a known good one, it's nice to have a spare anyway.

I had one fail and the symptom, which is common, is it would shut off randomly, but just immediately start back up again using e-start, can't remember if just popping the clutch would re-start it too. Some of the solder joints develop almost invisible cracks and apparently become intermittent connections. I read somewhere it's designed to shut off it if misses seeing one pulse. Anyway, the best way to fix is simply resolder every joint, adding a tiny bit of solder if needed. Only takes maybe 15 minutes if you're experienced with soldering. If that didn't have any effect there are other things you could test
 
I'm familiar with the repair methods and also the swap with a known good unit trick. Those are still options I am looking to explore. But after playing with these bikes for years now, one thing I haven't really seen are brand new replacement units for the Stock TCI black box.

Can you even get new black boxes from Yamaha anymore?

I was mostly curious about actual plug and play replacements or units that are brand new. Modern components, modern PCBA, that kinda thing.
 
You said you'd love to repair yours, so I threw that out there.
 
The only thing that makes my hair tingle is the continual use of the term "CDI" on that Carmo website. Hopefully it's just a translator thing...

It might well be a CDI, but it's replacing a .... Doesn't really matter all that much.

A replacement box would be the easiest thing in the world to make. A single micro, a minimum interface to the outside world. Not available in '80. The advance "curve" is a straight line to 3000 rpm and whatever degrees if I remember right and then quit. And nobody is going to hack it and steal bank accounts or launch a nuke... Trivial. I used to do this like X2 every day and it didn't demand $300 per sale... Unless the plan is to just sell one :)

I fixed one once that was working intermittently. I have no idea how to troubleshoot one but this is what I did. I ran the bike in the dark while looking at the circuit board, I saw sparking going on at a dry solder joint, touched a hot solder iron to the bad solder joint and it was fixed.

I was able to buy all the parts (except the chip) to fully repopulate the pcb for about $20. The only things that really fail are the electrolytic caps and the output transistor. The other failures are the solder joints. Average soldering skills will often yield you decent results.

Do it, add vacuum advance and or TPS mapping.... I'd buy, do testing.

I won't believe you're from the future and will probably call the cops on you.
 
Greetings All,
I am a newbie trying to troubleshoot a Hitachi TID12-01 on my XS650GS - 1980. I have 3 questions:

1) Is there any step by step process to verify the Ignition Unit on the bench?
2) I cannot find a circuit diagram, there is one posted but mine has a different chip - a Hitachi Quad op-amp HA17902P
3) does a compatibility matrix exist? I have seen TID12-02 and TID12-02C available on the web - I would like to find out if I could use this model on my XS650GS

Thanks in advance

I bought a GN250 unit as a spare. I have only plugged it in and the bike started right up. Now sure about the running yet. I think it was $20 on eBay and then you have to make a harness. Good luck.
My old TCI unit had coating all over the board. You have to remove that coating before you can redo the solder.
