Dan made some more progress.  Used 317 devices that are complete (all cap and pot on small board) to provide 10V and 5V to VIC Matrix.  Combined with Power Supply supplying 12V I now have the inputs I need to continue testing.   I Installed K8 to test it.  First noticed no digital input on M.  Fixed this by putting a jumper on screw terminals for K11 Jumper from G from K2 to M1,M2 on the screw terminals.  On my test system I just used output directly from K2.  The jumpers do the same thing.

Did not get desired results.  Went to check using my trouble shooting steps from K8 write up.   I needed to know where test points I used match the PCB layout so used traces from K8 above.   I found 3 problems with the layout.   All three transistor have problems.   If you want to match Stan's circuit the following changes to labeling should be made.  The circuit traces appear to be correct.

Q2 should be Q1 a 2N3906 that faces down PNP (power into emitter)
Q1 should be Q2 a 2N3904 that face left (2N2222 should also work) NPN (ground into emitter)
Q3 should be MPSA20 that faces down PNP (power into emitter)

NOTE:  all the collectors and emitters are on the wrong sides.

I will make changes on my board and continue testing.

I will make changes on my board and retest. 

Making changes above fixed problems board now works properly see scope shot below. Second picture is front view of panels for K2 and K8.  Third picture show power input to VIC Matrix.  You can see the two 317 devices mounted on back left leg I am using to set 10V and 5V input and power supply to left that provide 12V.  All 3 go to screw lugs in front of the power card.

I have noticed that without external wires running all over the place signals are cleaner. I have the frequency set to 41.67hz yellow trace the same value I have been using in my other testing.  Blue trace is the analog signal generated on the board it is set just above the minimum level where clipping occurs.  This can be raised with idle control.  All the front panel controls work.  Missing test jack (has not come yet) but switch works as probe is on switch output. All front panel wires for K8 go to screw connectors.

Happy New Year Everyone 2021 !!

Earl Re This  Corrections First noticed no digital input on M.

Fixed this by putting a jumper on screw terminals for K11 Jumper from G
 from K2 to M1,M2 on the screw terminals.   

========================
Can you take a few Picture of K8 From Side or Top so we see
this how you made the "putting a jumper on screw terminals for K11 Jumper from G
 from K2 to M1,M2 on the screw terminals.    "  so other can  see the perspective of any changes required or made.

So if we have to make a addition or change we do it now
so done we can edit/change board or pins if required so done, and these notes an be added to word doc

Dan

I have noticed that without external wires running all over the place signals are cleaner.

Great !!!

Just Wondering that your using the older picture K8 with pins  not  DB 37 card?
  I put that pic here if for any reason pin notes needed.
or for placement in doc as you mention jumpers etc

Note this is far better layout and a improvement from the estate photo which it all we had to go on
i attached so we remember( some times it helps to back track before we move forward)
Dan

Great  Earl on the 317's power feeds , small and effective,
nice to see the control panels migrated over to matrix.

Dan

Dan,

Picture below, but I am using jumper as signal to K8 comes from Digital means board  K11 which I do not have.  So I am just routing the G signal from K2 which is an input into K11 so it shows up on K11 screw terminals to the K11 M1,M2 output screw terminals.  M1,M2 are the inputs to K8 and K3.  So by doing this I have these inputs without the acceleration function.  When you add K11 or replacement you just remove jumper.  This is good enough for my testing as I can manually adjust gate on K3 and frequency on K2.  I did the same thing with my test system but just routed signal directly from K2 as I am using wires in that system.  Do not recommend changing anything on VIC Matrix board for this.   NOTE:  This works for initial testing but I did find when I went to combine the signals cross the transformer I needed to invert input to K8 see signal reference falling trace on K8 circuit diagram.  M11 provides M and M inverted you just choose one you need.

Just used the old card picture because I was using the circuit traces with pictures posted earlier in this post I could see new board had same same layout.  I had copied them into a word document so I could get them all on screen at same time. Just did not think to put markups on new card.

The 317 are great others were talking about the chip to generate 10V so when I went looking for it I found these it is cheaper to buy these than all the parts - 5 of them are $7 on Amazon.  Just type in LM317 on Amazon site.  They will also do 12V but need to supply at least 14V for it to work.

Great I think that is easier to follow now as many not familiar with the letter connections as we are,
which are marked on the board,

seams those training screw terminal are handy to have  hey ? beat the hell out of sitting with pens paper trying to play connect the dots

Dan

I needed to invert input to K8 see signal reference falling trace on K8 circuit diagram.

this is a important point to expand or show
and or note in word doc

Dan

Earl If possible please send marking or picture of new k8 transistor placement
and we will make note corrections

re npn and pnp  orientation is there a picture of the new orientation,
as  it helps others to see follow along and or make corrections same time

Re K11 I think you have card, if you need i can try assemble a throttle to tps to k11 for you.
you should have both k11 and tps (throttle position sensor card 3 wire)interface card

Dan

Here is your again K8 Bom  for other to find 
 

Dan

Here is the picture of K8 with transistors installed in correct location and correct orientation and correct labels should be.  Second picture is my hand drawn version of Stan's circuit that I built test board from.  I included it as it has pinout for the transistors and NPN and PNP labels.  I used this to check board as the power and ground lines showed me the correct orientation of the devices on the board. Easy to find pin location and diagram just search on internet like this (2n3906 pin locations).

Note:  For this board the base center pin needs to be bend toward the flat side of all three transistors and the board diagram should have the flat side by the base pin.

I do have the K11 Digital Means board.  I plan on building it but have not needed it for initial testing.  I have noted the inversion I did to signal in my test thread.  In my test system I used one of the unused OR gates on K2 to invert pulse and fed that to K8 as signal gets inverted every time go through a logic device.  I only noticed in combined signal going to primary coil as ramp up was in space and not in the pulse.  NOTE:  It is also possible signal got out of sync when I add changes to Stan's circuit to raise gate signal from 5 volt logic level on K2 to 12 volt logic level need by K21.  I plan on checking if the boards corrects both these items.

if you are relabeling board I updated BOM so Q numbers match Stan's circuit and labels on drawing above.

Thank you Earl much clearer now as
we can follow,  but others reading now have a chance to follow
as we go forth
Dan

for those following here is stans k11 and the new tps pcb convert from a now
 standard pedal 3 wire tps or tps sensor or throttle body sensor
out puts going into k8 k2 k3  as
Earl describes

 

I decided to check what parts I needed to build the VIC board this morning so I could order what I was missing.  I had made a list of all the parts but figured rather than just count what I had I decided to install them and then list what was missing.  Turns out I had most of the parts I was a little surprised how much I actually had.  See picture.  Turns out most of what I need is diodes and capacitors and a few switches.

Dan like the labels on the board the small capacitor number as well as value was very helpful.  There is one capacitor label missing on lower right side (right of the connectors at bottom of board). I assume it is 0.1uf 101.  Also the 1x label is missing from the G/COM landing pad but it looks like there is no good place to put it.

nice work 
this board came from a group of builders,  we can add the cap note

Also the 1x label is missing from the G/COM landing pad but it looks like there is no good place to put it.
Re this please circuit  or place it in MS paint and I make adjustment for your and others

Hi Earl Making the changes to vic

here for other connections you mentioned  for g/com
 following are the notes and yes for cap value

also note we are going to do a db 37 pin version of vic
but  checking auditing this one fully first as rather complex
did not want to change thing  until we  got all notes on board.

this is a good example why thanks for your fresh eyes also I am increasing font sizes
on board by triple as too small

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

For those Watching reading these are the training tools we preserve improve and share that
Stan and Stephen Meyer left us all as the foundation. of training with little improvements  and good consistency
 so old school and big spread out so we know how they work. latter SMD and consolidated can occur but for know we
get it easy to understand and assemble

lable back

Added Changes to Vic Board Geber update jan 2021

Thanks Dan,

I was going to ask for Geber file will help me get everything hooked up right.  I want to know where the various circuits are on the board.  I recognize most of the parts so I have a general idea already.  I have order missing items but it will take a couple of weeks for some of them come.

ok , , like to see if the traces on matrix work ok to the boards ok for your i see you jumped over rails
 do you have a k3 there?
i have next few weeks off to make correction if any needed

updated the vic gerber added the labels to back
