Well if someone figures this seemingly-retarded issue, ill try and scroung some presents to ship.
No joke a dozen engineers have been working on this.
Counter not in sync, randomly generates a number???!

It takes a year for this company to design and make and ship this item so i need to have this fixed, out of the box its not working.
What has been done so far...
isolated and individually tested all componontent for functionality
(theres not much components as you can tell)
still stumped figured it was wired wrong, tested and traced all wires. Nothing came up faulty, Then i got wise and decided to draw up a schem and just rewire it,,, was the same schematic essentially.
WHAT IT DOES
once u push the button it activates the actuator, which pushes a ball which drops on the lever/switch which counts and displays on the screen.
Its a very essential tool in Fracing process in the oil fields... pumps a ball down hole which is pushed into a crack in the shale formation that holds it open.
*the switch is not electrically connected to the counter.
THE ISSUE
when you press the button, it randomly counts and displays a number. If you push it, it will randomly count a number from 1-7 and add to the display?????
figured there was backfeed from something but cant figure it out. Someone suggested a loose ground or some ground issues?
Here are some more pics to show what we're working with, all ripped apart for testing and what not.
This is the main unit
This is the lever that trips the counter
This is the Display You can see the activation switch on the left half of the bottom.
The display has the digital flip flop actually built into it on the back of the unit. This is what we figured was bad and have another on order or spair.

Any ideas how to get the unit to accurately count would be great, always on the comp will try to answer everything soon!
