BSD Ball search problem

[millsy]

Couple of questions I ask  
Well a bit of an essay on what I have done so far.

Machine is a Bram Stoker Dracula.
Original faults when I got the machine : Turned machine on - Powered up, Started ball searching (all different solenoids activating one after another), then launched ball, bumpers, slings etc seemed to work ok, sounds there, display fine, half the P/F lights N/W, mist contraption did,nt seem to work, Test mode worked ok except  it was in French. Noted fuse missing F111 missing - Replaced it. Found a few wires off a solenoid under the PF and reattached it. Started machine again and eveything operated as previously. Carried out Switch Matrix test –( Refer Pict).
This is what I found after checking all switches.

Both these switches display both switches when one switch activated
Traced problem to boards (MPU or Driver), Sent Driver Board out for checking & repair & another working MPU fitted (Thanks Ken) as well as replacing the Myst opto board (Thanks Homepin).

Current Faults
Would not boot up  (one led on at MPU), Disconnected all ribbon cables + J212,J205,J207,J209. Restarted machine (All correct Leds on MPU working) Reconnected all plugs & the machine booted up. Still seems to be looking for a missing ball (all solenoids activating one after another & myst motor starts moving across) There is no CHECK FUSES F114 and F115 fault displayed.
Carried out switch test

Seems to be only the OPTO switches playing up, When switch 56 is activated it shows switch 55 on the display. Also Switch 55 shows as OPEN,  Another  weird thing is the launch button does not work, Hitting right flipper launches ball.
My main question is having these N/W optos cause the ball search problem ?

[Homepin]

Check the mist multi-ball driver board (under the PF - incorrectly called "24 opto board") - correct name "24 INCH opto board"

There is a small green choke on the board that has very fragile legs - you might be lucky and be able ro re-connect it if it is fractured?

This board can cause all sorts of weird ball search and multi board  and opto problems with BSD.

Replaced it last week with one of your boards Homepin.
How about the 10" opto board - Do these cause problems.

[Homepin]

  - oops - OK, that's not it then....

the 10 opto board controls all of the the ramp optos, try unpluging it and see what that does to the error messages?

noy so silly question.Do you have 4 balls in the machine?

[studley67]

also have you got the right balls in.the balls can bind together in the outhole lane and not register if they are magnetised.i.e sticking together.

[millsy]

Tried 1,2,3,4,5 balls 
Switches -Outhole,Trough 1,2,3 & 4 all register in the switch matrix.

[studley67]

i'm stumped. have you tried a factoy reset.or new roms?

[millsy]

Have reset many times.
Has another MPU board from Ken fitted so it has a different ROM, also Ken checked & repaired the Driver board. Hoped this would solve this ball searching problem.

[studley67]

this may sound simplistic,but if the machine is looking for the ball and expecting it to have registered as being in the out lane,then it hasent put it there.i would check solinoid fuse,then wiring to out kick

[studley67]

disregard my last post.i whent back and read the whole thread.you have probs.do you have another w mach to test these boards.just a thought.

[millsy]

No unfortunately,just an EM
All solenoids work in the solenoid test, the ball will eventually kickout into the launch lane - you can play the game but whilst playing,the solenoid firing sequence is happening.
Just thinking,maybe its not ball searching but doing the solenoid test (The solenoid test in the test menu)

[studley67]

this ones for beaky to solve,me thinks

[goodolddays]

Just a stab in the dark Kev, but are you sure you have power to Opto's?

[casperthefriendly]

Have the switches been wired back to front at some point in the past? Check the colours...
