HITACHI Electronic Ignition - DATSUN/NISSAN: Description

Two different basic ignition systems are used, with additional minor variations between Datsun/Nissan models. However the principle of operation on all systems is the same. Both systems use an electronic distributor, an IC ignition unit, ignition coil(s), battery and wiring harness. See Fig 1 through Figure.

This design is used on 200SX, Pickup, & Stanza models. 

The ignition system for 210, 280ZX, 310, Maxima, and Sentra models uses one ignition coil with a single spark plug for each engine cylinder.

The second system, used on 200SX, Pickup, and Stanza 4-cylinder models, uses 8 spark plugs. These models use special distributor caps, having 8 spark plug wire outlet terminals and 2 coil wire inlet terminals.

These models also use 2 ignition coils, one for the spark plugs on the exhaust side of the engine and one for the spark plugs on the intake side.

This design is used on 310 & Sentra models. 

On 200SX, 310, Pickup, Sentra, and Stanza models, the IC ignition unit is located inside the distributor. The stator and magnet assembly also has a different shape than those of other models.

Depending upon the distributor used, the IC ignition unit may have a 2-pin connector (210, 280ZX, 310, Maxima, and Sentra), a 3-pin connector (Pickup), or a 4-pin connector (200SX and Stanza). The IC ignition unit internal circuits also vary from model to model.

On 210, 280ZX, and Maxima models, the IC ignition unit is mounted externally on the distributor housing. The unit is connected with 2 wires to a pick-up coil located inside distributor. These models also have a fusible link between battery and ignition switch.

The 280ZX and Maxima models, which have 6-cylinder engines, feature reluctors and stators with 6 teeth. Other models have 4-cylinder engines with 4-tooth reluctors and either 2-tooth or 4-tooth stators.

This design is used on 210, 280ZX, & Maxima models.
