Bump
Basically all switches and solenoids fire as they should both in test and in game with one exception:
If you get 2 balls locked and it puts the 3rd ball in the shooter lane all is well, once it hits either of the upper roller over switches it resets the game and clears locked balls.

Both switches work as they should this is happening only do to the start of multi ball.
Tested and every thing works by hand and in test mode.

All 4 ramp switches, the up posts and kick out solenoids work.

If we lock 2 balls and remove the ball from shooter lane and manually touch things it scores but does not start multi ball. You can touch any switch on the pf but if the upper roll overs are hit it starts multi ball left kicker kicks out ball and before it can make the ramp switch game resets.

Tested many times above way is the only reset cause. Instantly starts back up and works perfectly.

tech info bump

last bump any documentation on boards, wiring or switch matrix?

No tech info for zacc or gen2 ?

Unsure why these are desired then....

"Other machines made by Tecnoplay during the time period Scramble was produced include X Force, Devil King, Space Team, and Hi-Ball."

Maybe manuals from other Tecnoplay or Zaccaria machines around the same era could be helpful...

Xforce? - http://www.ipdb.org/machine.cgi?id=3539

Edit: also, this site for gen2 http://www.zaccaria-pinball.com/gen2/

Maybe so thanks for the info.
Anyone else know if info on exact machine exists? I do not own this it is a buddies machine just trying to help get an idea what is going on.
