    Bro this video is well explained.
    06:38 i have a problem with fuse 52 for starting the car, it keeps breaking and my car won't start and i have to constantly replace it.
    I see number is 20 on yours, mine is 15.
    Do you have any idea why mine keeps breaking?
    Thanks

    • @kiwiwifi
      @kiwiwifi 2 года назад +1

      Change the fuse to 20Amps fuse. Your current fuse is constantly blowing because your starter relay has a damaged resistor. Replace the relay with one from Mercedes’ Benz. More expensive to buy from Benz; but best practice in this situation.

    CORRECTION: In the video around 3 min you talk about the fuel pump and the fuses. You state that one side of the FUSE is connected to the ECU and the other side is connected directly to the fuel pump. Incorrect. The fuse gets +12V directly from the PREFUSE BLOCK, the other side of the fuse is connected to 1 RELAY contact, the other relay CONTACT ties directly to the FUEL PUMP. In short the relay is getting controlled by the COMPUTER via the low voltage of the relay COIL. The POWER side of the relay is separate from the computer if that makes sense. My comments are intended helpful, NOT to be critical. Thank You for shooting the video - I know that is a lot of work.

    Hey there ... great videos .... here is my odd problem ... it is a long story. Maybe you can help me, I know what caused my problem. I have a 2006 C-230 Mercedes Sport with 63,000 miles. I had been looking at my fuses to try to disable the car alarm that kept going off randomly. I did not even touch the fuses as I figured I would later that day and my big mistake was leaving the fuse cover off since I knew I would be back later on. The problem is I went for gas and figured why not get a car wash. I did and as I came out of the wash I heard the radiator fan louder than usual. I pulled off to the side of the car wash and turned off the engine and then the fan came back on .... I pulled out the key and it still stayed on. Then I opened the hood and I saw that I had left the fuse box cover off and looked closer and I saw some small drops of water on the fuses. Murphy's Law. I had left the cover off and then got a car wash and water had somehow sprayed under the bonnet. A bad coincidence. I dried it off as best I could. The fan stayed on. I drove it home and it stayed on even without the key. Right now I have the negative terminal off the battery to stop the fan. I will readdress the problem in the daylight tomorrow. Any thoughts ?
