Chronic consumption of the car battery power shortage, resulting in the vehicle can not start, often bring great inconvenience to the owner.mobile power plant

Modern automotive circuit complexity, power equipment and more, such as audio, security, central locking, electric windows and doors. These electrical equipment, the ignition switch is closed, there is still power supply, therefore, find the vehicle power consumption, should first figure out which electrical power switch after the ignition switch, and then one by one excluded. Automotive emergency start power expert advice:

Turn off the engine, audio, air conditioning, pull the handbrake, close all doors, front nacelle cover, trunk lid, observe the instrument panel with or without indicator light, if there is no indicator light, battery positive terminal in series with a multimeter measuring current, should normally display 0.00 ma, when useful electrical work, the current between 0.03ma to 0.6ma display.

1. Check the lighting system, small lights, brake lights, handbrake lights, gear lights and interior lights, door lights are closed.

2 car cabin cover lights, trunk lights, etc. are closed.

3. Anti-theft check, remove the alarm to observe the current.

4. Check the air conditioning system, blowers, air conditioning switches, electric fans, etc. are closed.

5. Use electrical power cord grounding, when a certain electrical appliances appear broken wire, ground, do not work with electrical, one by one should be ruled out the point of failure.

Car power consumption of many factors in the maintenance process, one by one for the power equipment should be excluded.
