I discovered this while on a mission to address my pitiful ignorance of all things car. It describes the structure, function and operation of the Zenith 36IV, then follows with some handy hints for the more common fault modes. I have found it useful.
The original doc was not easy to read, so I have OCR'd it into Word, altered the font and layout a bit and removed many Oxford commas, in good OLLR pedant style. Attached as a pdf.
