Battery Drain Diagnosis and Repair

Diagnosing a battery parasitic drain can become a real challenge with today's late model vehicles with so many electronics. In this video, I will run you step by step to measure the amperage and to isolate the circuit, causing the battery drain. I used a couple of tools to measure the amperage, such as a meter with an amp clamp and an oscilloscope. I used a multimeter to perform a voltage drop test on fuses to find the source of the fault and also a thermal imaging gun. #voltagedrop #batterydrain Timeline: 0:00 Intro 0:07 Battery parasitic drain 0:16 Setting up the tools 1:55 Zeroing the meter 2:45 Amperage measurement 3:39 Scope setup 4:20 Scope amperage measurement 5:40 Setting a different multimeter 6:15 Zeroing 2nd meter 10:45 Voltage Drop Test 15:30 Thermal Image Testing 17:06 Passenger compartment tests 18:10 Bus Network Waiking up 18:45 Left side of dash voltage drop test 21:58 Identity faulty circuit 22:30 Second fuse box thermal image test 24:35 Removing to identify fault 24:55 Fuse Voltage Drop Chart 27:00 Analyzing Electrical Circuit 29:11 Checking glove box lamp 29:42 Checking trunk lamp 31:31 Identity source of fault 32:30 System description and operation 33:17 Repair confirmed Disclaimer: The content of this video is available for informational and educational purposes only.
