ELECTRICAL SYSTEM
A typical engine electrical system generally consists of a starting motor, a battery-charging generator (alternator), a
transistor combination voltage regulator, current regulator and cutout relay to protect the electrical system, a storage
battery and the necessary wiring.
Additional equipment such as an engine protective system may also be included.
Detailed information on maintenance and repair of the specific types of electrical equipment can be found in the service
manuals and bulletins issued by the equipment manufacturer. Information regarding equipment manufactured by the
Delco-Remy Division of General Motors Corporation may be obtained from their electrical equipment operation and
maintenance manuals. The manuals may be obtained from United Delco Division, or from the Technical Literature
Section, Delco-Remy Division of General Motors Corporation, Anderson, Indiana.
In most instances, repairs and overhaul work on electrical equipment should be referred to an authorized repair station of
the manufacturer of the equipment. Replacement parts for electrical equipment should be ordered through the
equipment manufacturer's outlets, since these parts are not normally stocked by Detroit Diesel Allison. For electrical
equipment manufactured by Delco-Remy Division, repair service and parts are available through United Delco Division
branches and repair stations.
