The minus is connected to weight

Current giving to the consumer is carried out on a wire which more or less difficult way always can be tracked to the accumulator as it and is visible on electric schemes in this chapter.

The feedback is provided with current-carrying metal details of a body or the engine. At the expense of it it is saved большее quantity of copper wires. In certain cases, despite it, the short piece of a wire is necessary for feedback maintenance when the consumer does not take places directly on metal. These wires connected to weight, always conduct to one of so-called points of weight which are scattered on a body and on which eyes for fastening of wires are screwed.

Minus the accumulator pole, certainly, too is connected with a body – "weight" as the autoelectrician will tell. Remember: a minus to weight.
