(4) Intermittent electrical failure of most circuits and maintenance of automotive circuit intermittent fault detection and maintenance is caused by faulty electrical connectors and poor contact between inter -wire interval between wires, and may also be caused by components or relays. Check the following items before deciding whether to scrap for a component or wire component.
① Whether the insertifier is tightly installed.
②The terminal stretch or launch.
③ Whether the terminal on the wire component is completely inserted into the plug/component and locked the position.
④ Whether there are dirt or rust on the terminal. Rust and dirt may cause intermittent circuit intermittent faults.
⑤ The damage of the interpreter/component skin is exposed to dirt and moisture.
⑥ The wiring insulation layer grinding causes short circuits on the ground.
⑦ Some or all the internal insulation of the wires are damaged.
 Whether the internal insulation of the wire is damaged.
(5) Find short-circuit circuit
Find short-circuit circuits
① Remove the fuse of the fuse and break all the loads of the fuse.
② Connect the test light at the position of the fuse.
③ Test the lights on the following circumstances:
[A] -Open the ignition switch;
[B] —— Open the ignition switch and SW 1;
[C] —The ignition switch, SW 1, relay open (connected to relay) and SW 2 off (disconnect SW 2).
④ When viewing the test light, disconnect and connect the connector. The test light is still short -circuited between the connector that is still lit and the test light goes out.
⑤ Lightly shake the fault wire along the body to accurately find the short -circuit part.
9.5 Parasitic leak search
Parasitic current is a typical static current. It means that after the power switch and other electrical switches are turned off, some electrical or circuits continue to consume the discharge current of the battery. Its unit is "MA".
Take cars as an example. After the automotive power switch and other electrical switches are turned off, the operating information of the vehicle needs to be stored in the memory unit (ECU) memory. Electronic quartz watches and electronic tuning radio equipment such as electronics are required. These electrical appliances save related data in a low -power consumption mode. According to the amount of automotive appliances and the level of intelligence, the power switch is closed for 5 to 30 minutes into the dormant state. In normal conditions, the current during sleep is only about 30mA, so the battery output is normal. On the other hand, many electrical equipment on the automobiles have inevitable, trace power consumption after the automotive power switch is turned off. These discharge currents are referred to as parasitic current.
The special tool for checking parasitic currents.
