4.6 Electrical Equipment
Electrical equipment system is single-wire, negative terminal of power sources and con-
sumers is connected to truck earth. Negative terminal of the storage battery is connected with
truck earth via remote switch.
Power sources are two storage batteries connected in series, and the alternator. Electrical
equipment tools and devices are connected by wires with polyvinylchloride insulation of various
sections. Wires in bundles are marked according to the electrical equipment scheme to simplify
their finding and mounting. Wires are marked on the nipples places on both ends of a wire.
Wire interconnection and their connection to devices is done through plugs.
For safe operation of the devices and systems follow the condition of fuses, installed in
the blocks. Do not use fabricated fuses such as crimped wires, bolts, washers, because in case of
network short circuit it will immediately destroy items based on electronics. Blown fuse should be
replaced by another one having the same operational current, if the fuse is blown for the second
time find and delete the failure.
