Accord failed to resolve leakage Vehicle: 06 Honda Accord 2.4L

Accord failed to resolve leakage Vehicle: 06 Honda Accord 2.4L
Mileage: 80000KM
Symptom:
2006 Honda Accord 2.4LCM5 produce a car, mileage 80,000 km. Users often reflect the newly installed battery power loss, does not start the vehicle.
According to the author of the new battery is often reflected in the case of power loss, then the vehicle may have leakage phenomenon. I decided to use the test lamp in series with the negative battery leakage location method of inspection, so the negative battery cable removed, access to the test lamp between the negative terminal and the negative line. At this point, I found that the test light just turns on the line, the flash went out a few times, but the interval of about 5s after the pilot light is lit again and no longer goes off, the circuit leakage phenomenon does exist.
Resulting in loss of battery power may cause include: ① the vehicle after the installation of equipment such as alarm, sound, radar and navigation equipment as a result of vehicle leakage; ② battery alternator does not cause loss of power generation; ③ some of the original vehicle electrical component failure lead to leakage of vehicles, such as the original car stereo and seat heaters.
The initial inspection of vehicles have been identified there is leakage, so basically you can rule out the possibility of generating electricity is not. I carefully examined the vehicle to confirm no later installation of equipment, vehicles, and then linked into the P block, pull out the ignition key and turn off all electrical equipment. Again test light in series with the cathode in the negative battery terminal wire loop until the test light lit, first unplug the engine compartment fuse / relay box 22 fuse (100A), pilot light goes out immediately, thus determine the fuse 22 under the jurisdiction of each branch there is leakage somewhere in the case.
Access circuit diagram shows, 22 separate the two branches fuse, alternator slip go by measurements, the generator output voltage is normal, indicating normal alternator power generation, excluding the branch fault; another branch and separation of multiple branches, respectively, by 4, 8, 10, 15, 19, 20 and 23 fuse power supply, so I remove these in turn fuse, fuse 20 when the disconnect wire, test light goes out immediately, which determine the leakage point in the 20th after the line fuse.
According to the schematic shows, 20, a total of six branches fuse to power, the six branches, respectively, by 12 to 17 fuse power. I installed fuse will recover 20 bits, followed by 12 to 17 fuse disconnect, unplug the 17 when the fuse (20A), the pilot light goes out immediately, which fuse 17 under the jurisdiction to determine the leakage branch .
Continue to have access circuit, I found that fuse 17 for the front passenger side power seat slide motor provides the power, upon inspection, the front passenger side seat motor switch back and forth catching the switch cover in the forward position, the switch cover to back After the pilot lights go out in situ. The author has repeatedly tested several times, the fault does not occur again, bringing the cause of the failure to identify.
Troubleshooting:
Repair the right front seat motor switch back and forth, failed completely ruled out.
