1.Low light and low volume
Fault phenomenon: the light is weak, the horn buzzes, the volume is insufficient, the horn volume is normal after the engine is running; When the throttle is slammed, the brightness of the light increases instantaneously. Idle running horn volume change little, light is still weak. Cause analysis: Battery deficit point, electrolytic liquid pair density may be reduced to 1.15. Electrolyte containing metal debris or dirt, plate on the active substance.

Cause analysis: Battery deficit point, electrolytic liquid pair density may be reduced to 1.15. Electrolyte contains metal debris or dirt, the plate on the active substance off more. Battery terminal piles are too dirty or have poor contact, loose screws, and poor bonding.
Check whether the circuit has leakage, short circuit or poor contact phenomenon.
Elimination method: thoroughly check and clean the battery, add or replace the electrolyte and supplement the charge and other maintenance operations. The density of the liquid phase in each cell should be consistent. Check whether each cell electrolyte is clean and whether the active substance falls off seriously. If necessary, the electrolyte should be replaced, and the battery plate should be cleaned and recharged. After confirming that there is no obvious effect after charging, replace the battery in time. New battery electrolytic liquid phase pair density 1.28.
2.After the engine starts, the charging indicator is not put out
Fault phenomenon: the charging indicator lights up or does not go out after the engine starts. Cause analysis: 1. The battery wires are connected in opposite directions, and the positive and negative terminals are connected incorrectly. 2. The generator does not generate electricity. Brush too short, adjust out of control, control platinum contact ablation. Dc motor copper head (rotor rectifier) too dirty, short circuit phenomenon. 3. Ac generator output conductor terminal cable.
Fault phenomenon: the charging indicator lights up or does not go out after the engine starts.
Reason analysis:
1. The battery wires are connected in opposite directions, and the positive and negative terminals are connected incorrectly.
2. The generator does not generate electricity. Brush too short, adjust out of control, control platinum contact ablation. Dc motor copper head (rotor rectifier) too dirty, short circuit phenomenon.
3 alternator output wire end loose or fall off, transistor loss or breakdown, power generation is obviously insufficient.
Elimination method:
1. Connect the battery conductor and the bonding cable according to the instructions of the vehicle.
2. The DC generator should replace the brush once when the vehicle runs for 10,000 km, polish the platinum contacts with platinum sand bars, check the regulator, and clean the copper head of the rotor. If necessary, replace the damaged parts and measure the power generation.
3. Check whether the conductor of the alternator is firm, disassemble and replace the brush or damaged parts if necessary, and measure the power generation.
3.The electrolyte was boiling and bubbling
Fault phenomenon: the charging indicator lights up or does not go out after the engine starts. Cause analysis: 1. The battery wires are connected in opposite directions, and the positive and negative terminals are connected incorrectly. 2. The generator does not generate electricity. Brush too short, adjust out of control, control platinum contact ablation. Dc motor copper head (rotor rectifier) too dirty, short circuit phenomenon. 3. Ac generator output conductor terminal cable
