1. Wire
The electrical devices on this model use 24V DC power supply. Audio and air conditioning are controlled by regulators, and the rated voltage of other electrical devices is 24V (DC). The power supply consists of two 12V storage batteries connected in series, which is equipped with a three-phase alternator with a rectifier. All wires connected to the circuit use insulated wires and can be identified by color.
The color and thickness of the wire No. 2 pre-color white black red grass green blue gray brown light green Example: R (there is a white wire on the red bottom) line color background color 0.85G (except for the insulation material core wire nominal name The cross-sectional area is 085mm2) Nominal cross-sectional area of the wire (mm2)
2, power supply device
The power supply device supplies power to various electrical appliances, including batteries, battery relays, start switches, relays, fuses, and fuse boxes. The negative pole of the battery is grounded to the car body. The start switch is in the OFF (OF) position, and power is supplied to the following devices through the battery → battery relay → fuse:
1) No. 1 terminal of indoor light, fuel pump and DCDC transformer
2) Start switch B terminal and air conditioning control panel No. 22 terminal.
3) The B terminal of the engine stop motor power supply.
When the start switch is in the preheating, running, and starting positions, the current flow is battery→fuse→start switch B terminal, BR terminal→battery relay BR terminal, so that the coil is excited and the relay contact is closed. When the battery relay contacts are closed, all electrical devices can operate.
