Searchlight Generator

[Tony Smith]

I'm seeking any information or manual on a "Nunn" or "Harland" 18kva generator trailer. The trailer is made by H E Nunn & co, Manchester and the actual Generator is made by Harland Engineering, Alloa, Scotland so I'm not sure of who's name the Generator take and it's proper nomenclature. It's powered by a Ford V8 and puts out 100 volts at 180 amps continuous. As this is a heck of a jolt, I'd like to know more about the electrical side of the Genny before I mess with it.
