Generator Regulators - BOSCH: Description

A two-unit regulator is used consisting of a voltage regulator and a cutout relay. The voltage regulator consists of a two stage unit operating on a double set of contacts. A regulating element of semi-conductive material, called a "variode", is incorporated in the unit. This variode senses temperature variations arising from the intensity of the charging current and ambient temperature.

To polarize generator, momentarily contact lead form positive post of battery to "D+" terminal on regulator (with belt removed). Never polarize by connecting terminal "B+" (on regulator) to terminal "D+" on regulator. Damage may result to regulator, cutout and generator.
