Ford Lehman 120

I have been trying to locate the tachometer sensor on my Ford Lehman 120 with no success. One mechanic mentioned that some tachs have a magnetic sensor on the flywheel. Another source mentioned that it typically is attached to the alternator.

Also I have discovered a wire near the alternator that comes off the port side engine block off of some type of sensor. I assumed this was originally attached to the alternator post but when I connected it there it overrode my engine kill switch at the helm. Any ideas as to what this wire is and where it should be attached. I am attaching a picture showing the alternator, the wire and the sensor below on the engine block.

Any suggestions will be much appreciated.

Re: Ford Lehman 120

Google American Diesel Corp in Va. The owner of the place, Bob Smith, is the grand daddy of the marinized Ford Lehman. He knows more about the engine than the next top 5 diesel mechanics put together. When it comes to the Lehman, he can diagnose problems over the phone better than most mechanics can sitting in your engine room.
