Ignition System - HITACHI Electronic: Description
The ignition system for Maxima, Pulsar, Sentra, and 280ZX models uses one ignition coil with a single spark plug for each engine cylinder.
Depending upon the distributor used, the IC ignition unit may have a 2-pin connector, a 3-pin connector, or a 4-pin connector. The IC ignition unit internal circuits also vary from model to model.
On Maxima and 280ZX 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 Maxima and 280ZX models, which have 6-cylinder engines, feature reluctors and stators with 6 teeth. Other models have 4-cylinder engines with 4-tooth reluctors and 2-tooth stators.
