Re: Yanmar Alternator question

Good news- 1) the alternator lives to be replaced another day. 2) Another mystery part identified (diode)

After troubleshooting- My alternator tested 14.2v well at the alternator posts but not at battery-  it turned out there is a confluence of wires at the starter post and this post nut was loose- tightened and all was good!
