Hey Guys, I havne't had a chance to look at it yet, but i'm pretty sure it's not the alt, because i drove back home on trailing a lone (about two miles) and i had the headlights on and stuff and the voltmeter shows that it was still charging... I was doing a lot of stop and go (traffic) when the this happened, so i'm wondering if it's extra strain on the system when that happened? I'm going to try to get out of work early and grab a new coil and see what happens...

oh, and i didn't add a fuse to the second gen coil, so it should be on the stock one still which powers both leading and trailing (if i understand the system correctly) so it shouldn't be a fuse problem. I'm giong to try to get it fixed tonight since i have dyno time reserved for tomorrow, i'll keep you guys posted.

My car recently did a similar thing, with the lights that is. I don't have a circuit installed yet, but I remember that when it would drop to idle all the lights would dimly come on and I could almost hear a buzzing sound. The alt was still charging at the time, but a few days later it went out on me. Don't rule it out just yet!

well, I just replaced the coil/ignitor unit, and everything is functioning again. Devitek, i think my situation was different because the car ran really poorly after the lights thing. When I have the chance, i'm going to take the ignitor out of the bad unit and see if the coil would work as a normal 2gcdfis, and if it works, then i'd think the transistor dieded, or else it's the coil...

Yep, it is still in the works. teejs and I are putting together a write-up for the simplified version of the circuit for people who want to be able to take advantage of this mod until we get some professional boards made. teejs is going to build one of the simplified versions for himself and take pics of the process since I don't have any electronics stuff here. Once I get the pics, I'll add them to the write-up and I will post a new thread about it. It should be fairly straight forward to build and only cost about $10 to $15 plus wire/connectors.
I'll post up some prices of the professional board today based on different quantities. I already have a pretty good idea of what the components costs for about 40 kits. We then need to figure out details as far as who can put together kits/ship/ and/or assemble. I would do it all myself if I could. It would just be too expensive to ship everything here and for me to then ship it back.
So far I have only seen interest from a couple people. I am sure there are probably more, but I need to know to determine price and so that I don't order a bunch of stuff that may not sell.

I did it how RX7Rox is saying. It works for the time being. There really isn't much room on this side of the engine bay when you have A/C and P/S. You could separate the back of the coil from the coil itself and mount that way. Maybe someone can come up with a bracket desgn for mounting. Maybe something that connects to the A/C compressor mount.

/me shakes his fits at the infernal Texas weather that requires A/C to live.
If you take out the old leading coil and cut that bracket in half, would it fit there?
Hmmm, I might have to experiment with this.

I'm doing this over the winter, I'll post pics when I get going on it. Basically, making a sheet metal bracket that hangs off of the strut tower on two sides, the inner and rear side of the tower. I'm mounting the 2G coil on the rear of the bracket and the j109 and eventually the trick on the inner part of the bracket. My goal is to have this assembled on the bracket standalone and use the existing wiring as much as possible. Also, I'm not cutting or gutting any existing wiring in the coil or the car if at all possible. Since my car is an 80 SA that should be possible. I don't have PS but do have AC so I definitely have clearance problems.

Rollin' coal and 53mpg!
Does anyone have a website that has a pictorial tutorial of how to do this?
As much as I'd LOVE to read through 4032541879565214577921 pages of it... everyone knows that the only thread on the RX7Club forum that's worth reading that's THAT long, is the Resurrection: Thong Thursday.

Here is what I have came up for a doubled sided layout. It needs a littlle tweaking, but is about what I want. You will notice that the parts are much closer together than the previous boards. I will have to look up some plastic boxes for mounting and maybe change the size/layout of the board to work with the box.
As for prices, the program lists the following:
Qty.
10 $26
20 $14
30 $10.05
50 $6.92
75 $5.35
100 $4.32
These would be my cost not included shipping and such so the final price to you will be higher. You see how we need higher quantity to make it worth it. The final price of a kit (with all the basic parts) depends mostly on who puts the kits together is willing to take for his time/effort.

I am currently working on a write-up for building the simplified circuit for this mod. I will create a new thread for it so it won't be burried under all these pages. The final professional board will be even easier to assemble. Just drop parts into place and solder.

Just wanted to give an update on my parts order from Radioshack...
DON'T ORDER THE PARTS FROM THEM.
They cancelled my order after shipping one part and charging the full amount for shipping. Back to the drawing board, I suppose.

Too bad, back in the day I used to love getting little parts for things I would tinker with, and those build-a-whatever component kits with everything on the board (the ones you use short wires and springs to jumper stuff) were the ISHT!
Sadly, now I avoid that place like the plague...

Sorry to hear about that, devitek. Hopefully you will get something worked out. Places that carry the parts like Mouser and Digikey, just get to be expensive with shipping and minimum order fees for a small quantity of parts like that. I think this is why we should make it in a kit form. That way we can do one large order from say Mouser, get the parts in quantity pricing (cheap), and people wouldn't have to mess with tracking down parts.
devitek: Did you want to be in charge of shipping boards, kitting, and maybe assembly of some boards as well? I think you said that you had spare time these days. It would be nice to have one person handle it. If it becomes too big of a load, we could split in between a couple people or you could pass it off and have someone else do it for awhile.
Once we know quantity, I can get eveything ordered and have it shipped to you if you want to do it. We can figure out pricing and details if you want through pm.
We should have the write-up for the simplified circuit done this week. teejs had all the parts, but he wanted to go to RadioShack after work Monday so he could get the exact ones specified. The parts he had would work fine, but he didn't want to cause confusion.
I too have become disappointed with RadioShack. I remember when they used to have tons of components and electronics kits. I guess they are just not profitable. RS now has pretty much turned into a cell phone store. BTW: I had one of those 200-in-1 electronic kits with the jumper wires. I think I still may even have it. My dad got it for me when I was 8 (about 20 years ago). It was a pretty cool thing.

Hey Kent,
I had a question earlier in the thread you or someone else was discussing getting a complete kit together with the coil and the TT. Well over the past week I have gone to a couple junk yards and I can say I have come across about 10 2nd gens and the all had there coils and fuse boxes. About how many coils do you think would need to be sourced in order to include them with the TT Trick.
I think I could get quite a few but I would need a way to test them.

Yes, another had a thought of doing a complete kit with coils and all. That may be a good option for some so they don't have to chase down coils on their own. Whatever people want to do is fine by me. We could have a package with coil included if people wanted that. I don't know of a number you would need to get. How much do you think you could get them for? I don't know of a good way to test. It would be possible to use a smaller 12v battery (lawnmower or motorcyle batt?) and a simple circuit to create pulses to fire the coil. That way you can see if it sparks or not.
The other option is that you could source the coils, and if people need one, we can send them your way.
