Hello
Can anyone help, I have been asked to repair an Ajax A25 but someone has cut all the wires off the I.F board, if circuit not available a picture of the I.F board fitted showing the connections of the wires would be good.
Many thanks.

Unfortunately no, it shows where the blue wires go but not the rest of them. I will carefully experiment!
Thank you
