My bally Beat the clock does have one failure.
Attached a phote shown the side targets in detail. It works fine but the lights for the 50000, 100000 and 150000 does not lit.
Also if knockdown all the side targets no extra point given, only by the individual targets some point are given.
Where do,i need to find a solution
The bulbs installed are ok

Quoted from Inkochnito:

In the manual there are settings for the drop targets.
Page 1-5, setting 43 & 44.
On page 1-12 it is better explained.

Ok thanks, need to,figure out how to check the register, can i change settings..
Sorry but is the first time working on this type of machines till now,only did EM and old bingo,s

Quoted from Inkochnito:

Are the lamps working in the test function?

CHecked the lamps in the testfunction option 90 of keyboard but lamp 50000. 100000 and 150000 don,t work
The red one special does work
Anything else i can check???

Quoted from Luckydogg420:

The transistors might be toasted.
Q41, Q56, Q25
They all run through connector J10
You could try to re-seat the connector

Re seated connector , but problem still there

Quoted from Inkochnito:

If the thyristors are broken there should be more lights out.
Thyristor Q25 is for Drop Target 150K and Game Over lamp.
Thyristor Q41 is for Drop Target 50K alone.
Thyristor Q56 is for Drop Target 100K and High Score to Date lamp.
On the Pinwiki page for Beat the Clock you can sort the lamps any way you like.
http://www.pinwiki.com/wiki/index.php?title=Beat_the_Clock
Or you can download the Tech Chart from my website http://www.inkochnito.nl

Its only the three lamps 50k 100k 150k the others are ok

Quoted from Inkochnito:

Check the vio-red wire (B phase) at the light sockets.
Does it have power? (must be yes because the special lamp works...)
Does the vio-red wire have a good connection between the special lamp and the 150K lamp?

Think we have found the problem. Checked the light sockets and all,of them have a resistor in between one of the connections, exept one is not there and wire broken, see pickture.
Do you think this resistor is realy needed? Or can i just connect both ends together.
In case resistor is needed do you know the type and value?

Quoted from Inkochnito:

From the images I see the manual is incorrect about the wire colors.
Phase A is Pink and Phase B is Violet.
Your problem with the light sockets is because of those missing or bad diodes.
They MUST be in place to get them to light correctly.
The small dics capacitors are there to lengthen the switch closure time.
Those old caps tend to create problems, so people cut them.
Replacing them would be preffable.
Stand-up targets also has them.

Peter,
Thanks for,your help and lessons learned. Will change out the diodes
Thanks
