3.2 Wiring Precautions
▪
When wiring, first confirm the position of the threading holes, and route the wiring
harnesses that need to be arranged outside the cabling out of the threading holes in order.
When wiring, first arrange the wiring harnesses outside the cabling, and then arrange the
wiring harnesses in the cab;
▪
When wiring, pay attention to avoid high temperature, oily, scratch-prone areas, fans,
exhaust pipes and other nearby areas;
▪
When wiring, keep a certain length to avoid over-tightening and loosening; the wiring
harness layout should be smooth and natural and cannot be twisted into a twist;
▪
The GA-Sensor host will rotate along with the rotating shaft. When wiring, leave enough
length and try to kill the left and right directions after installation.
▪
After the wiring harness is arranged, cut off the excess length of cable ties. After the
installation is completed, the removed original tractor accessories are properly stored and
the garbage generated from loading is cleaned up.
3.3 Electrical connection method and precautions
▪
In the process of connecting the power cord to the battery, first connect to the positive
electrode and then to the negative electrode;
▪
Before starting the wiring work, you should connect the power supply. After the power
cord is connected, you can connect the controller, monitor, and steering wheel power
harness connector to avoid damage caused by direct power-on or multiple power-offs;
▪
In the process of connecting the power cord to the battery, first connect to the positive
electrode and then to the negative electrode;
▪
Pay attention to the use of the wrench when connecting the positive electrode, and it is
strictly forbidden to bonding; (when the wrench contacts the positive electrode of the
battery, the other end of the wrench is strictly prohibited from touching any conductive
items, especially the metal parts of the original tractor)
▪
12V / 24V battery, when the positive of original tractor battery is cut off or the original
