phenomenon phenomenon: a 2006 Honda Accord 2.4 L CM5 annual output of cars, mileage 80000 km. Users reflect the newly installed batteries often lose power, not the normal start the vehicle.
check Analysis: According to the author of a new battery is often reflected in the loss of electricity, indicating that the vehicle may exist leakage phenomenon. I decided to use the negative electrode of the battery series test lamp checking the leak location method, then the negative battery cable is removed, the test access between the negative terminal of the lamp and the negative line. In this case, I found that the test light just access line, several flashes extinguished, but after an interval of about 5 s, test lamp is lit and is no longer off again, the circuit described leakage phenomenon does exist.
may cause battery power loss include: ① After the installation of the vehicle anti-theft device, audio, navigation devices, parking sensor and causing the vehicle to drain; ② the alternator does not lead to battery power loss power; ③ original some car vehicle electrical component failure resulting in leakage, such as the original audio and car seat heater and the like.
has been determined that initial examination there is a leakage phenomenon of the vehicle, and therefore the possibility can be ruled out of the generator does not generate power. I carefully check the vehicle, after the installation of the device is not confirmed, the vehicle is then linked into the P range, and the ignition key is removed off all electrical equipment. Again the test lamp connected in series with the negative terminal of the battery negative line loop, to be tested after the lamp is lit, firstly disconnect the engine compartment fuse / relay box 22 fuse (100 A), pilot lights extinguished immediately, thereby determining the jurisdiction of the fuse 22 is present somewhere in the drain branch of the case.
Now the circuit diagram (FIG. 1) can be seen, the fuse 22 separated two branches, one branch destined for the alternator, the measurement, the generator output voltage is normal, indicating that the normal power generation of the alternator, this negative slip failure; other branch and separated plurality of branches, respectively, passed through a No. 4, No. 8, No. 10, No. 15, No. 19, No. 20 and No. 23 of the fuse power, so I turn the unplugged fuse, the fuse 20 when the disconnect, test lamp immediately extinguished, thereby determining the point of the drain line 20 after the fuse.
The circuit diagram shows that a total of 20 fuses to the power branch 6, respectively, through which six legs 12-17 numberFuse power. The fuse 20 I bit recovery means, followed by No. 12 to disconnect the fuse 17, fuse 17 when the disconnect (20 A), pilot lights extinguished immediately, thereby determining jurisdiction branch fuse 17 leakage.
Now continue a circuit diagram, I found that the fuse 17 provides power to the front passenger side of the power seat slide motor, upon inspection, the front and rear side of the front passenger seat movement motor switch cover in the advanced position switch jammed after the switch cover back into place pilot light goes out. I also tested several times repeated, the fault does not reappear, bringing the cause of the malfunction identified.
Troubleshooting: front right seat motor repair longitudinal movement switch, failure to completely eliminate.
