Electric Stop Of The Engine - Valtra 6000 Workshop Manual

35. Autocontrol IV

Electric stop of the engine

E ---models have not a stop control knob but the engine stops
when the ignition switch is turned to the 0 ---position. The fuel
injection pump is moved to the stop position by a solenoid
spring when the current to the solenoid is cut---off.

When the ignition switch is in the ON ---position, the solenoid
is energised and the magnet keeps the pump in the running
position.
The solenoid earth wire (white) has been fastened under the
bolt of the injection pump potentiometer fixing plate. The sole-
noid supply wire (171/Black) has connector X32 and the wire
goes via the socket X19 on the front wall of the cab. The elec-
tric stop requires a different ignition switch compared with the
normal stop system. From date 9403 all Mezzo---tractors have
an ignition switch no 325 53200 which can control the electric
stop.
If the engine stops during driving, the solenoid magnet can be
damaged or there can be poor wire contacts. When current is
switched on to the solenoid, a click sound can be heard.
Note! On later E ---Models, the automatic stop control is a
standard equipment, see pages 312/1 and 312/4 and wiring
diagrams on pages 350/12 ---17.
