When the vehicle power supply fails during driving, it is often necessary to take some temporary measures for first aid. The first aid methods for several common power failures are described below. Shanghai Lianjie Electric Co., Ltd. teaches you how to correctly judge the wiring rules of the power system terminals.
1. The domestic silicon rectifier generator has a mark or name next to the terminal, and “ten†or “B ten†is the “armature†terminal. This terminal should be connected to the “10†pole of the ammeter or battery; “F†It is a "magnetic field" terminal that is connected to the "magnetic field" terminal of the regulator; "E" is a "grounding" terminal that should be connected to the "grounding" terminal of the regulator.
2. The generator is connected in parallel with the battery, and the negative pole of the battery must be grounded. The positive pole of the battery is connected to the positive pole of the motor through the ammeter (or directly). The static electromotive force of the battery is often 11.5V~13.5V, and the output voltage of the generator is often limited to 13.8V~15V (24V electric system 28V~30V). When the generator is working, the normal voltage is 0.3~3.5V higher than the battery voltage. This is mainly to overcome the line voltage drop, so that the battery can be fully charged when it is charged, and it will not be overcharged.
3. The field coil of the alternator with external regulator is grounded by two types: one is that the magnetic field coil is directly grounded inside the generator, such as the generator of the domestic Dongfeng EQ1092BJ2020 car; the other is that the magnetic field coil is no longer The inside of the generator is grounded, but it is grounded by a regulator, such as an AC generator that liberates the CA1092.

Iroko (Milicia excelsa) grows in tropical Africa as 50 - 60 meter high straight and often branchless tree, with an 1upto 2.5 meter wide trunk.
The wood sources from this tree various from butter yellow to golden brown, from soft pearly green to brownish red. The grain is often straight, but can have a slight wave. It contains a substance that dissolves in organic solvents which increases the drying time of varnishes/lacquers finishes.
