Hi All, I have just obtained this interesting little generator. It is a Powerunit DC/AC 250 watts No.1 (American)(1A), Model BD-12-A, Pincor specification SS-2856 1942. I believe that the actual engine is a Briggs and Stratton ( no idea of the model) and that it was used in WW2 to charge batteries for wireless sets. The mag on this unit doesn't work which probably means that the coil will need to be replaced. I would like to find out more about these units eg wiring diagram,manual etc so if anyone could kindly point me in the right direction I would be very much obliged. All the best, Kev.
