Guys,
I found an old Sierra dismal board and was going to use it in a dummy diesel for effect.
I was wundrin if anyone had a manual so I knew where to hook up power and speaker.
I’m going from memory, but I believe the power came from a battery that was plugged into the board.
I don’t need the battery, but I do need the male plug.
Unless a couple of the screw mounts provide power.
Thanks,
jb
You have diesels?

Stan Cedarleaf sent me the manual.
I don’t even think the board works.
