    Hello Rich: Thank you again for another superb diagnostic video. How many times ea have I mentioned how amazed I always become with your capabilities. At keast you had a newer Benz where the modules go to sleep. I have an older Benz and the modules are not designed to go to sleep so I must keep a Noco battery maintainer hooked up while not in use. When I had my businesses wether it was a BMW , BENZ, etc we would always find these types of vehicles with a high parasitic draw caused by faulty modules. The thing is that the European car makers have stuck it to us all. They will sell you a new module but it must be recorded with their OEM SOFTWARE. You can have all of the aftermarket programmers ever made but if you don't have the latest OEM programmers it will not operate. Again, God Bless & my best to your family, TMP from N.J.

    good find Rich, as an IT diagnostics guy retired, searching for what's really wrong is not always easy. You can spend hours eliminating "what is not the problem". I just finished up today, eliminating a Parasitic Draw of 1 amp on an '02 7.3L Ford Excursion. a prior mechanic had bypassed the Ignition Switch "ON" wiring and hooked the Alternator 'I' terminal direct to the output Stud post.... Overnight, it would start. Leave it several days, and it would NOT start.

    Parasitic Draw is third on my diagnostic tree for drained batteries. 1. How old is the battery, after charging what is the CCA? 2.What's the alternator output under load? if all of these are good then 3. What's draining the battery? Basic diagnostics go a long way. Great video Rich👍

    One time, I was looking for a parasitic draw on a friend's car. I had the meter hooked up and was starting to pull fuses when I heard a click from under the driver's seat, and the draw disappeared. I checked and the motor was too hot to touch. It turned out that the control switch had gotten mashed downward and stuck. I popped it loose, and everything was fine. I advised him to be careful of the switch when getting in and out of the car.

      Good afternoon sir: Yes there are 2 batteries for the E500, S500, & the S 600. The main battery is in the trunk ( large ) & there is a small battery mounted on the p/s firewall. The small battery is for an emergency voltage supply for the electric brakes. Usually the small battery goes dead cause most mechanics ignore any maintenance or testing thereby a light comes on in the dash cluster & tells you that you are in deep S it. TMP from N.J.

    Nice. My car has the same issue. Did mine by trial and error. With driver’s seat module connected, battery died. Went out of town for 3 days with passenger side connected, came back and car started without needing to jump it. Since I need only the driver’s side to work all the time due to having multiple drivers, gonna swap them and wire the passenger side so it’s operable with key on by connecting the Acc and 12v together. This way the module gets power with key on. Since mine is a C320, it can be done without removing seats.

    Another huge issue with many Mercedes Benz vehicles from this time period is the actual wiring, find many got a plastic soy based wiring harness insulation & it literally becomes brittle & peels off or rodents snack on it ,,also in the headlamps it really comes apart from the light,heat & breaks down ,i just replaced a OEM Mercedes headlamp assembly the other day due to a physical hard short that fried the HID ballast & had smoke in the inside, that light wasn't cheap & was almost $1000 for it & the module, seen many perfect looking Mercedes end up in the scrapyard because of electrical issues

  • @alouisschafer7212
    @alouisschafer7212 Год назад +2

    Pretty sure they don't do this dual battery stuff anymore I can't think of any regular Benz that has two batteries except the Hybrids of course.
    This car is from a time when Mercedes still made really good cars.
    Id love to have a mint early mid 2000s C or E Class preferably with the Diesel and 5G Geartronic automatic that's a million mile drivetrain right there.
    Mercedes also makes Wagon Versions of their cars called
    "T Modell" I'd like to have one of those.
    Saw a mint 1998 (I think) E Class T Modell Turbodiesel in Blue recently posted for 1500€. MPG ain't the best on a stone age Diesel like that I mean it was special to have a Turbocharged Diesel in a car back then 😅
    Old mercs are just interesting cars I think. Especially because they made great Diesels and thats kinda unique.

    • @FordBossMe
      @FordBossMe  Год назад +6

      So what you need to do is you need to open your doors that you're going to have open that you're going to be working in but then you're going to want to take a screwdriver and close all your latches so it thinks that the doors are closed but on the 2003 Mercedes-Benz on this one it has a actually push button for the light so you put a little clamp over the button and secure it into the closed position and open the trunk and close the latch on the trunk while it's open so it thinks that the trunk is still closed then remove your negative cable from the battery put your meter and your amp draw a setting but one side to the cable and one side to the Post and then wait about 20 to 30 minutes so all the modules shut down and when you see your amp reading you shouldn't be anything more than .050 amps theoretically we don't want any more than 0.030 amps
      Once you have given about a half hour time for all the modules to go to sleep you start pulling one fuse at a time and checking your meter to see where your amp draw stops or drops down

I think Mercedes DID have an E460 (or E450?) during the early 00’s…(?). By the way, can you work on my Mercedes to troubleshoot and diagnose future electrical issues ? Nice “detective” work 👍

      I've got this exact same vehicle, 2003 Mercedes E500, it's a 5.0L engine. I as well dealt with this parasitic drain problem for a year and a half (also being my daily) and went to the extremes of making a "kill switch" for the negative terminal of the main battery since I had gone through 3 batteries already. I did all the same diagnostics as he did in the video with no luck. What my drain was actually coming from was the 039 fuse I believe, next to steering column which is the "lower control unit / Switch off relay". Ended up realizing that these models and year range create parasitic drains due to "short circuits to ground" over time. Only realized this because the extensive research I've done with others having same problems but a lot of them coming from other electrical areas. Wasn't ever consistent with cause. It's really nice though too be able to use the vehicle the way it was intended instead of constantly killing the battery every time I got out of the vehicle lol.

      This is not easy to explain in a text so I'm going to do it one time and then I'm moving on
      You remove the negative cable from the battery and you take your meter and you put it over in your amp selection like on 20 or 40 whatever your meter is and then you hook your positive lead up to the negative cable the part you disconnected and you hook the positive lead up to the battery post and you'll start getting an amp reading it should be less than .5 ideal less than .3

I checked for any fuse that would give off a charge even when the car is off but even after removing those fuses the problem still doesn’t go away, my temporary solution was to add a switch to the main battery so every night I flip the switch to completely disconnect the battery from the car. It’s not a huge hassle but I wish I didn’t have to keep doing that.

      -If you don't run them in Winter and don't put a ton of miles on them they are great cars. Also new cars/trucks are $50k+ which this car was just under when new. $1k-$2k is not too bad for service per year, plus if someone steals your 20yr+ car (Chicago) you don't feel so bad.
