2.16.9.4 Auxiliary Electrical Equipment
 The fuse box: has 15 fuses, total, 7 for normal use, and the others for spares. Fuses are used to protect
electrical equipment. Replace burned out fuses immediately. Each fuse’s rating should coincide with the
requirements on the electrical schematic. When a fuse burns out, it is necessary to troubleshoot the cause
immediately. Do not substitute a fuse with a higher or lower rating, as this can result in damage to the
electrical system.
 The ignition switch is used to turn on the electrical system and preheat and start the diesel engine. Put the
key into the ignition switch, turn the key clockwise to the ON position and switch on the electrical system.
Turn the key further clockwise to H and switch on the engine preheater. Turn the key still further clockwise
to ST engage the starter. After the diesel engine is started, release the key and it will return to the ON
position automatically. During normal operations the key is always in the ON position. When the tractor
will not be used for a long time the key should be removed from the ignition switch.
 Rear Trailer Socket: For powering the trailer taillights when the tractor is equipped with a trailer, the tractor
is equipped with a rear trailer electrical socket. For the socket wiring layout, please see Figure 2-42.
