I need help. Have accidentally pulled wiring from my diesel horn oil storage tank about 5 years ago and can not find a wiring diagram for it. Anyone got one that can tell me about the wiring?
Thanks!

Dear Fish,
One wire goes from the AC terminals to the tank. the other goes from the other AC terminal to the pushbutton. A third wire goes from the other side of the button to the remaining contact on the tank.
Have fun!

You mentioned a total of 3 wires two of which go to ac power and to a switch to ac.   

However,  My oil tank has 4 wires soldered to the pc board.   One on each post marked AC, a third to one of the AC connections, and a fourth to a small connector with a yellow wire on it.    Playing with all four wires I can only get a weak horn sound from it.   How should I connect the 4 wires??

The Bach-mans description was of wiring a working unit, to a transformer, and switch, by the method described in the manual.
 Your description, or understanding of it, might be a bit off. From transformer ac terminals- One ac leg(wire1) to oil/horn terminal #1, the other transformer ac leg(wire2) to switch #a(com), then from the switch #b(n.o.) leg(wire3) to oil/horn terminal #2. 
You are asking more about the internal wiring of a circuit board, and trouble shooting it, which is another set of questions altogether. It sounds like ac hooked to the ac leads should make it sound. It could also have a bad speaker, volume switch(?) or amplifier. If no one answers in a few days, I suggest re-posting this as a new question in general discussion where more eyes will see it.

I hope this will help as it's all I could find. I was able to follow the wires and it looks fairly simple. Use the fourth and fifth pics with the zoom feature.
