Functional desription of NEPTUNE 5-51DE
Start the motor by shortly turning the key (5) into the start position. When you let go the key, the key
moves back to the ”ON” position.
When the key is turned to the start position, the start relay (13) is pulled, and the start motor is turn-
ing the motor.
Circuit board (A2) is monitoring the thermostat (E) on the high pressure pump, the motor oil switch
(D) and the oil level switch in the high pressure pump.
If the thermostat (E) on the pump is closing (failure) is input 8 connected to ground, which causes
the LED to light, and at the same time output 15 is connected to
ground

If the charging generator (I) is not charging, wire (Y) in the regulator (O) is getting 12V and also the
input 7 on A2 is then getting 12V, which makes the charging light lighten.
On this model it is important that the jumper on A2 (2A) is NOT mounted, for the charging system to
work properly.
