Nissan Micra Distributor & Ignition Coil Specs - T4T83581B/T4T83582B (EL-37)

This document is a scanned page (EL-37) from a Nissan service manual covering the Ignition System — Distributor — Service Data and Specifications (S.D.S.). It provides a distributor specification table split between M/T (manual transmission) and A/T (automatic transmission) models. The M/T distributor type is T4T83581B and the A/T type is T4T83582B. Shared specs include a firing order of 1-3-4-2, counterclockwise rotation, an air gap described as 'close but not touching,' pick-up coil resistance of 970-1,170 ohms, cap and rotor head insulation resistance of more than 50 megohms, and cap carbon point length of more than 10 mm (0.39 in). Vacuum advance curves differ by transmission: M/T models range from 0°/9.3 kPa (70 mmHg) to 6.5°/22.7 kPa (170 mmHg); A/T models from 0°/14.0 kPa (105 mmHg) to 3.5°/24.0 kPa (180 mmHg). Centrifugal advance is 0°/600 rpm to 11°/1,900 rpm (M/T) and 0°/800 rpm to 9°/1,900 rpm (A/T). A second table covers ignition coil types CIT-130 and STC-130, listing primary resistance of 1.0-1.3 ohms and secondary resistance of 8.4-12.6 kilohms at 20°C (68°F). Useful for testing and diagnosing ignition components.
