Swete Jesu lighten up Duaneage your whole purpose here has been for profit.
But what could be more fun than that.
 
They're flocking!

They're flocking!

Thirteen 1st gen TSCU's in various states plus two additional leads.

sending a few to Duaneage??? Ive got an intact plastic housing I think that I can send him for fitment.
 
That's the plan Chuck :)

If I have the proper connectors to mate with the hard shells, I'll try making a setup for testing them this weekend. I know for certain two are working except for the self cancel.
 
I'll make up a test jig to work with them. I converted my GS1000G to GS650 controls and manual operation but I can duplicate it quite easily.

And how would you know that?

My, my, where have I seen those before? 13 sounds about right, of course that doesn't include all the ones I sent out to other's, Chuck you got a few.
I think I did a pretty good job beating down the bushes to find those, considering how scarce they've become. The one's with the tape on, tell what they do or don't do, there were two that fully worked, except they'd "hang" up every so often. For the longest time I didn't really know if the problem was with these, or my bike. I decided the bike was good, and patience and perseverance proved me right when I finally found a good one, for the sum of $20. And not long after that I found another good one, maybe another $20 or so. And I recognize it now, it's the one in the plastic bag with the rubber boot on it.
Don't let that one slip out from between your fingers Dale!

Now, get back to work! Doc!
 
Because one is marked as such, and the other, my old one, you tested on your '79.

Well, I guess that answer's my question.
This is a big initiative, I wish you guys success in this much sought after solution to a on going and well documented problem with these problem prone stock TSCU's.

I don't know what kills them, never had a problem with the one on my Skunk that I put over 24K on. But I think it's water going down the inside
of the plastic sleeving covering the wiring. Once it works it way to the inside of that TSCU nothing good can be happening for sure, and then there is the vibration also. Even if no water got to it, air can get in through
that sleeve and through the hot and cold cycles I would think condensation
could develop and that wouldn't be good either.
 
Jim, I just noticed the patent you referenced in your above post#56 used distance to cancel the signals. The ones used on the Suzuki's 1st gen TSCU's used a set amount of time.

Upon release of the switch, a microprocessor reviews the vehicle speed by way of a speedometer input line and references a lookup table to determine the proper distance at which to turn off the signal. Generally, the faster the vehicle is travelling, the longer the turn signals are left on.

You had me all giddy over seeing that schematic you attached, until I read the details.

Darn... :(

Dale, it Is Duanage's reference that he plans to implement for this fix. I'm also giddy waiting.

But to your concern, I'm sure that having or no having a distance input will not preclude a (555) timer from measuring time. You can resume the giddiness.
 
How can you state there is a micro processor in the original design if it's not the correct schematic?

So there may not be a chip, but there is a microprocessor. (see schematic attached) Are you also going to provide free firmware?

There is an I.C. on the board. Whether or not it is micro processor based is unknown at the present time. I haven't been able to ascertain what it is and I tried.

Rusty, it must be getting late where you are. If you go find Duanage's post, you will find his reference to the patent. I simply downloaded it and found the section that referenced part #500 which is the IC he referred to and is also specified by the patent as a microprocessor. Easy peasy if you were not so tired I'm sure.

It is actually quite easy if you have any familiarity with patents. I have been doing a few searches recently so, perhaps I'm a little more up to speed on these things.

Post #55 in this thread.

I've got a lot going on right now but I would like to make one of these on a breadboard prototype. If I can create one from scratch I'll provide plans to everyone so it can be made. No miminum orders or committments from anyone. I'll get an identification on the IC used and see if it is commonly available still.

Either way it's not rocket science and the Suzuki unit did it without a chip.

I'll take a dud or two to investigate what happened with them and explore using the old case for a new circuit.

I'll send you a PM with my address.

I'm giddy about seeing Duanage's progress and especially the firmware released under GNU license.
 
Jim, I'll let duanage specify what he meant when he said "build this".

Personally I didn't read where he said I'll build this and considering this thread is on the 1st gen unit's, my take on what he implied may differ from yours.

I guess the simplest way would be to send him a PM and ask.

Additional information.

The case marking on the I.C. is NEC (brand) D4020C. A 4020 is a 14 stage binary ripple counter which in my limited knowledge makes sense. It would have been used as a timing device.
 
Stop arguing semantics...just build one that does what its supposed to do and youll sell me 3 at least

Chuck, sometimes it's necessary to find out what the author intended.

What's un-necessary is the use of disparaging comments.
 
Im not trrying to be derogatory at all Dale. Duaneage said he would trouble shoot one if he got one sent to him...I dont have one to send him though. Ruined the two bad ones I had trying to figure out how to unpot one. There has been a schematic found that has a layout ( granted that may need a mod here or there ). By "BUILD THIS" I take him as meaning he would trouble shoot an old one and build new working units.

What I an seeing is someone says "X" and someone says they are asleep or up at a late hr. etc etc...that was the basis of my comment. Then it goes back and forth all the time.

A build for the unit has been thrown around for well over a year as far as I can remember and there is obviously a demand for them. I just wish I had an electronics backgrouind and had the ability to build three for myself. But I am just a wrench.
