The engine electrical system consists of a starting circuit, a battery charging circuit, and protective and monitoring devices. Electrical power for cranking the engine is supplied by two 12 volt, 100 amp-hour lead-acid type batteries connected in series. A slave receptacle facilitates external connection to the batteries. The starter assembly is a 24 volt, heavy duty unit consisting of a starting motor, a solenoid, and a drive assembly. The battery charging alternator with integral voltage regulator and diode rectifier recharges and maintains the batteries in a fully charged condition after starting. 3-2. BATTERIES.
