Hi Guys!
Symphtom:
Switch error nr 26 (one bank drop target)
The drop target switch does not work switch is not registered in the switch test.
(Switch is Opto not a leaf switch)
I have bought a new opto for Whirlwind 1 bank drop target from a pinball shop.
They give me one with a part number GK105A
Unfortunately it does not work.
I have checked all the related stuff like voltage and row/column connection.
The small board is pretty simple one resistor one opto and the connector.
(the connector is brand new)
I cannot compare the catalog of the GK105A becouse i dont know the original Williams part.
In the manual there is only this kind of information:
OPTO1 Opto Inter LG 10mA.
I assume they sent me a wrong or defect part.
I have mounted on the board correcty according to the scematic!
Please advice!
