Abstract
To provide a positive indication that a battery has been reversely connected to a self-contained electrical network, for example a vehicular or boat network, a diode (24) of low current carrying capacity is connected across the terminals (25, 26) of the network, poled in blocking direction. Upon erroneous or reverse connection of the battery (13) with reverse terminals, the diode will immediately burn out, thus providing positive identification of such a reverse connection, even if only of such short time duration that the main rectifier diodes were not yet damaged. To prevent spurious replacement of the diode and thus elimination of the indication, the diode (24) can be molded into or cemented into a depression or groove formed in the insulating support plate (28) supporting the rectifier element.
