Would anyone in the room have a RAVEN in French?
Usually, we see it when we go to the TEST menu and the texts are in French.

Hello,
I do not have a Raven on hand to take a picture, but I know exactly how to connect this board.
This is not a plate with diodes, but a small board with resistors, physically located between the four bumpers and slightly curved shape.
It contains the polarization resistors of the transistors mounted under the playfield, as well as the resistors for the two flash lamps (and also a resistor for the scrolling lamps ~ driven by the auxiliary lamp driver).
This board has nothing to do with the contact matrix, and with other small boards with diodes.
This board is powered by 24 volts (common wire - 222 - red/red/red) that is seen at the top of the photo.
On the other hand, for departures having two wires (the three resistors on the right of the photo) (colors 144, 644 and 633 - brown/yellow/yellow, blue/yellow/yellow and blue/orange/orange) goes to polarise the base of the transistor, and use small resistors 1/4 W 4.7 K. Look like OK on your board.
They are R1, R2 and R3 on the schematic.
The two middle departures, with a single wire, go to flashlights. Wires are 077 and 088 (black/purple/purple and black/gray/gray).
There is something wrong here : resistors should be BIG ! because they are 5 W - 8 ohms ... and someone replace them by small 1/4 W 4.7 K !!!
For sure, flashlights works badly or not at all, with a such value. But may be, the lamps have been replace by LED ??? check that, but for sure, this mount is not standard.
They are R4 and R5 on the schematic.
For the last wires on the left, there is obviously an error. The color 311 (orange/brown/brown) indicates that it is the wire controlling the two groups of lamps, but supplied with 6 V DC.
There should be there a big resistance 5 W - 0.33 ohms and it should be connected to 6 V and not to 24 V.
It is R6 on the schematic.
