    Gentlemen, I have a quick question for experts on the subject. I have a VW Bora 1.9 TDI 90HP, what is the correct current consumption in amps at the starter by the starter. Lately, something does not start and it turns hard, maybe the battery is worn out, I will be measuring tomorrow at start up and at rest. But I would like to know before the measurements, and nowhere I can find it. Some write 150 and others with 600Ah, and according to the factory I can not find.

    Inrush current is not constant. On a cold engine in summer it is different than warm and just as winter in -30 in the morning as warmed up.
    It can be 50A and it can be 200A.

    A colleague is right, it depends on several components (temperature, engine condition, etc.)
    However, 50 And this is probably a slight exaggeration, I would be inclined to 200-300A

    Since it turns hard, you need to be interested in the state of the starter - once in 20 years you should replace the sleeves, brushes, grease and then wonder what to do next. As for the current - it depends on what power you have the starter, the diesel was probably 2kW - divide yourself by 12V and you will roughly have a value. Often "heavy" turning is a damaged rotor. Anyway, it is enough to measure the voltage on the clamps during filming - drop below 10.5V - battery discharged or sulphated.

    Gentlemen, thanks for the info, I have already bought a new Varta 74Ah 680 boot battery, but I wanted to make sure that the starter is not whacked. The old battery had 12.50v clamps, when it was filmed in the morning it went well below 10v, and barely turned the starter, and there was no talk about starting. Today my son came back from college and said that when he stood 2-3 days, the alarm mermaid sounded less trumpet, I think it is probably a battery, though I will check the consumption tomorrow, as I wrote at the start and stop. I will plug the meter into the circuit and wait 30 minutes for all devices to go to sleep.

    Just don't think about checking the starting current with a simple meter plugged in!

    Normally around 200A. Like a carrion starter it will 400-500A.

    I know how to measure the consumption current at rest, but I have a small problem. I have the DT-266 clamp meter in my hand and I do not quite understand where to set the measurement of the consumed current, because I can see that it has 200 and 1000A but alternating current. to what range to set, whether only variable measurement can be on this meter.

    Unfortunately, this meter is only suitable for measuring alternating current.

    Thanks, I thought so, although I'm not an electrician. I installed a new battery before measuring the power consumption at rest, after connecting the meter and waiting about 20 minutes for the car to sleep, the consumption on the meter varies between 0.01 and 0.02A, the meter is set to 10A, I think everything is fine with consumption, probably a scrap battery .

Topic summary

The discussion revolves around the starting current of the VW Bora 1.9 TDI starter. Users note that the inrush current can vary significantly based on factors such as engine temperature and condition, with estimates ranging from 200A to 600A for a diesel starter. A user experiencing difficulty starting their vehicle suspects a worn battery, which was confirmed by low voltage readings during attempts to start. After replacing the battery with a Varta 74Ah 680, the user measured a resting current consumption of 0.01 to 0.02A, indicating normal consumption levels. Concerns about the starter's condition were also raised, suggesting that maintenance may be necessary if starting issues persist.
