Hi Pinsiders!

I have a question about the coils which move the (open / close) eyelids of Rudy. If you have serviced Rudy's head before this is a question for you.
Somebody told me the manual contains false information about the type of coils in the mechanism.
The manual describes using 30-1100 (usually red) coils only in Rudy's head (2 for open and closing eyelids, 2 for moving the eyes). For controlling the eyelids one coil is mounted horizontal and the other one vertical. One of those should be a 31-900 (usually blue) coil. My question is should this one be mounted horizontal or vertical?
Thanks!

Thanks! I had a look at the manual before. In the picture you see that both vertical and horizontal coils have the number 11, which refer to 30-1100 coils. The thing is that according to my information all FH machines were delivered (flaw in the manual) with one 31-900 coil and one 30-1100 coil (one mounted horizontal and one vertical) What I don't know which one needs mounted where and if it makes any difference on the reliability.

Thanks! Exactly what I needed.

I just put everything together, also replaced transistor Q22 and checked the diode, but the blue coil continuosly overheats. Any ideas?

Thanks for this suggestion, will do this after I found the cause. I replaced the blue (horizontal coil for the eye lid closing mechanism) and the transistor, but unfortunately after a few tests the blue coil is burned again. (Diode is still fine) Any ideas where to look? (I'm still learning on electronics a bit)

the eyelid's mechanism itself looks ok. Only maybe with the eyelid's open the lids move down a bit slowly, when the vertical coil is released. When the horizontal coil is triggered the eyes shut immediately.

SOLVED; thanks everyone for thinking with me. The problem I had is that the transistor Q22 kept blowing after replacing it. The reason was that the diode circuit got a defect. I wasn't the diode itself, which was still fine. That is what confused me. In the end is was it the wiring on the J122 connector. The connector has two 'bridge' wires to connect the diodes into the circuit of rudy. One of the wires did not connect well, probably caused by cabinet movements over time. So be sure to check this wires when you have a problem with the solenoids of Rudy.
