Datsun 280Z 1997 Electrical Starting System Schematic and Circuit Diagram

datsun picThe 280ZX was branded in the American and Australian markets as the Datsun 280ZX; and in the local Japanese market as the Fairlady Z. In the 1979 model year in the American market, it was co-branded Datsun by Nissan through the 1983 model year. These were considered transition years as Nissan began to phase in their new global brand under the Nissan name. The Japanese market got both 2.0 L and 2.8 L engines. The 2.0 L-engined Fairlady Z used the L20 engine common in Nissan family cars of the same era. Export markets all got the L28-powered version. The preference for 2.0 L engines in the Japanese market was a by-product of taxation laws. Two trim levels were offered in America, with a no-frills 2-seater and the Grand Luxury (GL) ZX carrying the full equipment list. Leather seats were optional, and an optional digital instrument cluster was introduced in 1982.

The 1977 Datsun 280Z starting system consists of battery, ignition switch, starting motor and solenoid. When the switch is turned on, the battery current flows coils of the solenoid and magnetizing the solenoid. The plungger is pulled into the solenoid so that it operates the shift lever to move the drive pinion into the flywheel ring gear. Closing of the solenoid switch contacts causes the motor to crank the engine and also cut out the “series” coil of the solenoid, the magnetic pull of the “shunt” coil being sufficient to hold the pinion in mesh after the shifting has been performed.

The following diagram shows electrical schematics of the 1977 Datsun 280Z starting system.
