I have a question about my Nissan 1988 NS40C outboard. I lost spark on both cylinders and I did a checkout of what could be wrong on the electrical side. The brown and black wires were disconnected and still no spark. So I checked the exciter coil and had 318 ohms. Looks like it is in specs. Pulsar coil read 21 ohms. Now I checked out two different web sites and got different specs. One said 30-46 ohms and one said 18-22 ohms. Does anyone no for sure what is the correct pulsar reading for my engine. It has the internal ignition coil cdi unit.
