    Do you measure on the ignition switch off? Maybe the collection is greater than 10 Amp.

    Do not turn on the ignition.

    Power consumption higher than 10A and that's why the fuse is burning :P
    The second reason may be the ignition turned on, and when you try to start with the meter it is not at all :)

    At the moment of connecting the power supply, some components of the car are started and the momentary initial power consumption is considerable. So at the beginning of the test, connect the meter and connect the power supply, and then remove the jumper.

    I guess that it is out, but what is the reason the car normally fires, but aku unloads in a twenty-minute, I do not know what is the matter and how it will remove

    How can you disconnect the alternator and check then.

    Very valuable tip.
    If the current was above 10 A all the time, you would notice.

    When connecting the meter, make a jumper (green) as in the picture, then disconnect it and then it will show you what is the power consumption at rest. Because the devices need some energy when connecting the voltage source, eg capacitors must charge, on the radio and other devices

    c200 2004 alternator also disconnected may be the right meter in the meter

    maybe it's about the right meter measure

    We think so too.
    Do as in the picture above.

    It's a pity you did not write about this unloading at the beginning.
    This car is most likely equipped with an electric heater. If it discharges the battery in 20 minutes, nothing else will do it without making a fire in the car. The heater has its fuse under the hood. Damaged (compact) control system causes that it is at work immediately after connecting the battery. The controller is a fixed element of the heater.

    Hello, do not do anything yourself if you have no idea how to go about it, preferably from books if you already. :)

    Do not connect the meter directly. Use a measuring bypass, eg this one

    https://sklep.avt.pl/bocznik-pomiarowy-100a-60mv.html

    which you include in a series of klam. And with the meter you measure the voltage drop on the shunt. You know the value of the current from Ohm's law. When the current flows 100A, the meter will give you 60 mV voltage drop on the shunt. As 100A is too much (and little sensitivity), use a smaller one.

    Preheating the air here is supposedly not here. Sometimes the heater was installed in engines, but there is no need for CDI.
    Disconnect the candles. Controllers of glow plugs fell here, only then they did not heat at all. Maybe it's another case ;)

    Hello, I know the old thread, but I have one related question.

    And is it possible to connect with a meter instead of an unfastened negative clamp and a positive one?
    I think so, but I'd rather ask.

    Checking Power Consumption in Car: Fuse in Meter with Attached Picture Setup Explained


    I am asking because in my car, I have not seen a negative clamp yet :) it is hidden somewhere in the back.
    I will probably see it when I have to replace the battery and then I will have to disassemble it all.

    However, from the shore, I only have access to the plus one.

    This is what it looks like:

    Yes, of course, you can use a plus point.

    You can also use an appropriate meter for currents that flow in cars, i.e. the clamp.
    As a rule, you do not need to unfasten anything, connect, etc.
    And you can see the entire process of increasing and stabilizing the current after connecting the battery / turning the ignition switch.

Topic summary

The discussion revolves around measuring power consumption in a car using a meter connected with a fuse, as illustrated in an attached picture. Users suggest that the fuse may burn due to power consumption exceeding 10A, especially if the ignition is turned on during measurement. It is recommended to connect the meter after powering the system to avoid initial high current draw from components like capacitors. The conversation also touches on the potential issue of battery discharge, possibly caused by an electric heater or faulty control systems. Users advise using a measuring bypass for accurate current measurement and discuss the possibility of connecting the meter to the positive terminal if the negative is inaccessible.
