Ignition Coil With Power Transistor DISTRIBUTORLESS Ignition System
Turn ignition off. Disconnect suspect ignition coil 3-pin harness connector. Measure resistance between specified terminals. See CHECKING IGNITION COIL RESISTANCE (ALTIMA & SENTRA 2.5L) table, CHECKING IGNITION COIL RESISTANCE (MAXIMA, PATHFINDER) table or CHECKING IGNITION COIL RESISTANCE (SENTRA 1.8L) table. See Figure.
