Electrical System Description/Operation
The electrical system basically consists of the starting motor and the alternator.
The injection pump uses an electrical fuel shutoff valve. The function of the valve was discussed in the fuel system
section.
The engine should have temperature and oil pressure sensors connected to indicators or wired for automatic shutdown.
The engine may also be fitted with a block heater or an oil pan heater.
