In this video we Diagnose a battery drain / parasitic draw on a Mercedes GL500.
The owner needs to jumpstart the vehicle every morning.
I take you through the steps you’ll need to take, to locate a battery drain.
Can we find what’s causing the issue?
Let’s Diagnose it together!

Some of you might have already noticed but at 12:10 i must have accidently hit the multimeter button and changed the setting from DC to AC before starting to record my findings.
It doesn't change the Diag in any way but the multimeter should have been (and was off camera) in the right setting!
Hi Dan .I’m a big fan , if I purchase DDTSB would it work in Canada ?
thank you Sherlock Holmes! that SnapOn thermal imaging gun accuracy is insane. I must get on so I can play ( testing 🙂 ) all day around in the shop 🙂 best regards!
Great job, Dan !
Excellent as always, Dan.
Wanted to check the comment section to see if anyone mentioned this, but there were just too many: there are tables (lists) on the internet that show voltage drop across 12volt fuses.
Was there a fuse for that module, and did it show voltage drop or current?
Would the panel light have been on with the defective controller connected?
What's funny, is live power is at modules while the car is off. Engineers failed on the programming for the wakeup algorithm. I've reviewed the programming myself.
Could you possibly narrow down the current draw by first measuring the input to each fuse box?
Great job Dan I have learn a lot from watching your vedios you the greatest
Good video as usual mate, but I must say that realizing its a Japan spec car will make a difference in diagnosis. If you have and im sure you have used merc wis, you will notice in the wire diagrams that there are often differences between a Japan, US or rest of the world car normally noted such as code 456 Japan or the like. That will make a big difference in what fuse fuse does what. Keep up the good work buddy
Great video, Danny!
9:12, dam Dan, your fingers should be ice cold
He's got a woman's hand!
Love the bloopers 🙂 keep up the great work
Brilliant as always 🙂
Great video, I am so glad that YouTube notified me that you posted another video.
I love solving battery-drain problems. I’ve solved them twice; both times, it was caused by a faulty alternator.
I'm doing a similar job on a 2003 Range rover, but the power draw is 80mA and kills the battery within 2 weeks of dormancy. I'm going to use the voltage drop method, and the camera needs to be next on the line of tools!!
