Tecate CDI Recreation - For Sale

[83ATC185]

You might look into Allied Electronics, they have all sorts of stuff.

One thing i noticed with the original parts, is they all drifted in value. Most of the diodes barely conducted (they were the main culprit). The resistors shift values from what they should have been. A 47 ohm, measured at 27 ohms!. They 91ohm pulled in at 97. A 30 Ohm measured in at 20. These are all carbon based. The resistances lowers as they go out and take heat cycles over the last 30 years. The metal film are much more resilient in call conditions. They have less capacitance and handle the higher frequency's better. I'm estimating 80Khz when the motor is twisting at 10k rpm. 4 magnets -> 8 north and south polls total. 8x10k rpm=80khz AC electric output.

I do not know if this would be any help at all to you whatsoever and you are probably aware of them but there have been Mototek CDI's advertised on Ebay the last few weeks for all the tecate years i believe. I am not sure if they are adjustable. What era these were marketed in, probably the heyday? I put a link to them in the Tecate group a couple weeks ago. Oh well, thought maybe you would like to know about them. Maybe someone knows about them or has one. Sounds like you are going to kick butt on the ones you are working on.

I hooked the CDI up last night... Carb was gummed up with old gas. After dealing with that and getting gas to flow through, it fired up. I fired it up a few times. Each time, 1 kick. It revs out really nice. I'm going to try and get a video of it this evening.

Maybe tonight I'll be able to get a video. Started storming and hailing as i left work.

In other news, I just dropped a bunch of money into tooling to start manufacturing the PCBs.

Are you actually making them yourself? There are a lot of companies overseas that can do it on the cheap.

[RubberSalt]

Yup, am making them myself.

I don't know if I would trust over seas. I'm using only the higher end components.

I do intend on selling these, and I'd like to offer a minimum of a 3 year warranty.

The coil wire has arrived. Has a much nicer and thicker coating that I was expecting. Very nice wire. Made in USA, just like it should be.



On some of the coil wires, I was seeing black and burnt wire. Mostly due to it flexing/breaking and getting thin where the wires come out of the cdi. As you can see, this is a much heavier guage wire.

This, like everything, is overkill. ☺

Does anyone have an idea where I can source just the 3 ping electrical connector for the CDI? The only place I've found a few places that have them, but they are a little pricy.

I hope I don't have to make mold/cast them.

Why not? That's where the VAST majority of electronics are made now. I'm all for American made but it seems like people associate trikes with being American; yeah they were/are popular here but they do not originate here. Just seems funny to me to be reproducing a part for a Japanese machine but then saying that an overseas PCB company wouldn't be able to make a quality part. This isn't a complicated circuit, how many layers does the PCB have? Is it even 2? I'm impressed you're reproducing the CDI but you could bring the price way down if you got a PCB company to make the actual boards and then you could just populate them when they came in.

I've considered having the PCB it self made overseas. That part is simple and isn't concerning. The cheapest I've found started at $184 for the first PCB. Making the PCB is cheap either way. I paid up front for some tooling I've been wanting. This was more or less an excuse to buy it lol.

Still waiting on it to get in >.<

I did some direct comparison to the OEM CDI. I don't have a method for charting or logging the OEM ignition curve, but audibly, it sounds very very similar. The RPMs race up just about as fast and the rev limit is right about the same.

I'm waiting for a few more parts to arrive before i finish up a few more of them. I owe some of these back to the community for the help provided about a year ago.

I'd give it 3-5 more weeks before I can start shipping these. I'm still in search of the 3 plug connector for these.

I really don't like the idea of providing a product that isn't ready to bolt up and go. None of that rigging, or guess work. i want an OEM replacement that is as easy to install as OEM and works as well as OEM.

Heck of an effort

[RubberSalt]

Made a new PCB design to accommodate the parts better. It's the same size as the original PCB. I didn't have the correct drill bits with me, but i figured for a test, it wouldn't hurt. plenty of copper to solder each leg of everything too.
