G'day Mates, this is Dana Bultitude on behalf of Rob Mannell in Australia. Rob has a Metrolpolitan Vickers GRS Type SA Search Light Signal, AC Mechanism, 110 Volt, Lov 110, Cycles 50 that he would like to wire up to make the colour lens mechanism move. He has gotten the 12v light working showing red. Rob would like to know is anyone in the forum has wiring diagrams with instructions to help him get his signal working. He says it has two coils connected in the top row of terminals, the two outer terminals are one coil and the two middle are another coil and he wants to know what voltage to apply to these terminals and how to connect to reverse the coloured lens. This is not a permanent magnet field coil. It was tested in 1959, with a label saying holding voltage 90 volts and dropout voltage 48 volts. Thank you kindly for your help in advance.
