Power Transistor (Frontier & XTERRA)

Power transistor is located in distributor. Turn ignition off. Disconnect distributor 2-pin and 6-pin harness connectors. Measure resistance between distributor 2-pin connector terminal No. 8 and distributor 6-pin connector terminal No. 2 (component side). See Fig 1. If resistance is zero ohms, replace distributor assembly. If resistance is not zero ohms, power transistor is okay.
