Yanmar Wiring Diagram. Yanmar code 128271 77200 alternator model lr160 741 hitachi ic regulator model sa a hitachi battery voltage 12 v nominal output 12 v 60a earth polarity negative earth direction of rotation viewed from pulley end clockwise weight 42 kg 92 lb rated speed 5000 rpm operating speed 1050 18000 rpm speed for 135 v at 20c 68f 5000 rpm. I can see that when the main isolator and key switch are closed on the buzzer is energised and returns to earth along the yw wire via a diode to the oil pressure switch which i assume is closed until there is some oil pressure to open it.
To make a connection the diagram should show a dot and to not make a connection the wire should show a half circle at the intersection. Ive seen a couple of photocopied owners manuals. Feel free to contact me at sheaftractor at or 815 284 3226.
