This is a repop I found several years ago on ebay. It was listed for a '38-'39 Ford DeLuxe car, which is correct. This unit was built as a solid state device. It was also used on the early 9N Tractor which had the early, small generator, p/n 9N-10000-A, which was a B-Circuit design, 2-wire/2-brush unit, output at 7 amps. When the 9N-10000-B generator was released, it was a 1-wire/3-brush, A-Circuit design and used the new round can cutout circuit. The generators remained basically the same, only increasing output to 11.5 amps, and the cutout too remained OEM on the rest of 9N production and all 2N production, except wartime models. The release of the 8N model in July, 1947, reverted back to a voltage regulator and a revamped generator; a 3-wire/3-brush type, A-Circuit design, at 11.5 amp output. The NAA tractor revamped both generator and VR as well, and the FAG-10505 VR for the NAA will work in place of the original 9N-10505-A VR but one would need to fab a mounting bracket for it. The early 9N VR mounted on the lower rear steering box on two cast bosses with tapped holes -see picture.
