Stan Meyer Resonant Interlock Circuit - Full Schematic 

 

Fire Pinto  took Don Gable's component value patent images, printed them out and started scribbling notes on them.  Then I decided I needed to tape them all together and start mapping stuff just to get it all straight in my head.  I added things that I found while comparing with the estate photos.  Look it over and verify what I have found. :cool:

I have a full schematic scaled down to 10% attached here.  You can download the full sized, full schematic and separate 12 sheet scans at the links to my website below.  There is some white space that I wasn't able to remove from the full size drawing, and the scan pages also have extra white space.  That should be changed to print them out on standard paper.  I can't seem to get it to work with the software I have.

going back through the schematics and photos, finding a lot of mistakes I made in the above attachments.  Working on that. ;)

Anyway, I have been tracing stuff on the boards in more detail and found a curious thing.  On the VIC cards, there is an extra part of a circuit not shown in the patent schematics.  It is part of the Voltage Amplitude Control Circuit.  It is an exact duplicate of the circuit around opamp A25, where the J signal " Analog Voltage" comes in.  It runs in parallel with A25 and inputs to the same pin 2 on A24.  This means another signal can be input to the circuit simultaneously as signal J.  I've checked and it is wired all the way through to the DB9 pin connectors, which probably run all the way to the GMS.  Can't get a good view of that.

So what would this signal be?  Maybe not used at all?  Most stuff I'm finding that is not used isn't wired, but this is.  I've attached a couple pics below.  Added the part of the circuit to the schematic, and put borders around those parts of the circuits in the photo.

Nice find Nate :thumbsup:
In the context of the schematics where the 2 opamp output's meet, after their 10 Kohm resistors join on pin 2 of A24, the 2 signals (analog voltage J and the unknown signal) could be said to have their voltages added, literally.
This opens up for having an additional control signal regulating the voltage which in the end feeds the primary TX1 coil, which means that there's a second way of restricting, or enhancing, the primary TX1 voltage, which btw also could be directly connected to the 12V battery via the 3-way analog voltage selector switch found on top of the schematics.

 

============================================

After researching this deeper, I think the second mystery signal comes from the Gas Feedback Control Circuit.  This is one of the big mistakes I made in the scans attached above.  This circuit is not in the GMS box but in the VIC box mounted on the side of the cage.  

The attached diagram figure 3-5 from "The Birth of a New Technology" plainly shows a signal from the gas feedback into the voltage amplitude circuit on the VIC card.  The "6" signal in the other attachment also makes it fairly plain. :)  There is also a 25 pair CAT3 style wire leading off of he Gas Feedback circuit board going into the wire loom in the VIC box too.  It goes into the "photo evidence great unknown" area, but I'm willing to assume that it splices into the DB9 connectors that daisy chain to each VIC heat sink.  Makes you wonder what purpose omitting the "6" signal from the figure 4 drawing would be? 

Now an operation needs to be thought through.  Is this designed to increase cell pressure when the GMS isn't calling for high gas demands?  The way the "J" and "6" signals are mixed in the Voltage Amplitude Circuit don't seem like the "6" signal could over ride the "J" signal to produce less gas in an over-pressure situation.  To me it seems like a way to keep a minimum cell pressure.

I'm a paragraph. Click here to add your own text and edit me. I’m a great place for you to tell a story and let your users know a little more about you.

It's good that we have independent peer review of Don's photos. Making revisions will help.

I haven't seen that thread (I wasn't there yet). I modified my schematic at:

Bodge RC filter from primary sense trace attached to PLL pin 3

 

==================================================================

So, Russ and I have taken a challenge to determine what the outlined components are here in this image, why they are there and to come up with an accurate Figure 5 schematic with those components in-place.  If anyone else would like to participate, by all means, jump-in and lend a hand.

This RC filter is not in the official Figure 5 WO92/07861 patent. It is a bodge. As for the cap, I have yet to look at.

Attached is what the VIC card should reflect now.

C12 could be some other nF value.

==================================================================

Yes, we will have to figure out what the cutoff for the RC filter is since it tells the PLL which way to adjust the phase.

I'm not real sure about this particular PLL, but I think with no input to the comparator it runs at the center frequency plus the offset.

 

Yes I think so.  It's the only regulator in there.

It's working in my sim, but the signal at the base of the TIP120 is even more crazy.

ok good, how about that 22k and cap? add that to the sim? anything change? 

also post the sim again I'm installing it...

22k resistor mix-up w/ RC filter in cell driver circuit

 

==============================================

Cell driver traced.

The 22k in the cell driver should be 1k ohm. During a previous tracing, the 22k got mixed up with the RC bodge.

The C (collector) and E (emitter) are switched up on the silkscreen for the 2 PNP transistors and the other bodge near the 100uF cap on Don's sketch, but wired as they should.

100uF cap is a bypass cap over the 5V rail.

This cell driver is becoming to look like a protection circuit. As I look.

How is an opto-isolator any different.
