The "headphone" symbol is for OHMS and is correct to use. A continuity check position on the meter will also work, it might have a little speaker, and a symbol of a diode on it. The meter is auto-ranging, this means it will read with the correct scale as needed. The volt position will do nothing (you were reading stray voltage from the leads and induction from near by wires, not the part, it has no volts to measure unless connected to something with volts in it. When reading the little M probably went away. and you are reading 1.5 ohms. When reading the other way, nothing would mean either it is open in that direction, non conducting, or has no resistance, full conducting. If the meter stayed with the same reading it had not connected, it was open (good), if it went to Zero through some numbers, it might not be a good diode. If it was a resistor, it would read the same both ways, and about 3 ohms or so (assuming it might be a ballast resistor for the coil).
Try it in the #1 terminal wire with the non conducting end toward the alternator terminal. Check it like this: Use the red lead of the meter as positive (it is) when it is showing nothing on the meter (in the Ohms position like you had it) with the black lead on the other end, mark that end for being towards the alternator. If it still keeps running turn it around, you cant hurt it, if it still keeps running, it is not a diode (at least it isn"t much of one). replace it with a 3amp 500 piv diode from radio shack, put the band end to the alternator.

Today's Featured Article - Experimental Tractors Article - by Danny Bowes (Dsl). Tractor technology appears to have nearly hit it's pinnacle of development. If you agreed with the subtitle, you are rather mistaken. Quite, actually. As a matter of fact, some of the technology experimented with over 40 years ago makes today's tractor technology seem absolutely stale by comparison. Experimentation, from the most complex assembly to the most simple and mundane component, is as an integral a part of any farm tractor's development
