October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Ignition Coil/Power Transistor Resistance

Disconnect ignition coil/power transistor harness connector. Measure resistance between terminals No. 3 (Red wire on Altima, Maxima, Murano, Pathfinder and Sentra 2.5L, Green/White wire on Sentra 1.8L and White/Blue wire on 350Z) and No. 2 (Black wire). If resistance is zero ohms, replace ignition coil/power transistor.
