LC120 leakage detection is a perfect solution

September 5, 2024

I rarely drive this car after the New Year, and I always lack electricity when I want to use it. The battery was replaced a few months ago. We can rule out a battery problem. If there is no problem with the battery, it means leakage. I have time today and I must solve the problem.

First find a universal watch, lock the car and remove the negative pole of the battery. Adjust the universal watch to the position of 10A DC, and change the red pin to the 10A jack. Then tie one pin to the negative pole of the battery, and the other pin to the removed negative pole cord.

Sure enough, there was a leak of electricity. The overbearing power consumption under normal hibernation was about 0.03 amps. The next step was to unplug the fuses and relays one by one and check the meter data.

The problem has been found. When the J/B50A insurance is dialed out, the value immediately drops to normal. That is to say, there is a problem with the circuit or electrical appliance under the insurance. It took a long time to find out that the insurance is for electric windows.

I plugged in the safety and got on the car and removed all four window panels. I found that the values had not dropped at all. I had to put them back on the same road and check other places. I was thinking that the most likely leak was the installed electrical appliances, so I removed the storage box. Observe, I found a green light flashing under the instrument panel
