    Default Fluctuating voltage when steering

    TOday I got my alternator back from the repair shop. It was another faulty regulator, after only 2 months since it was replaced. The problem was (again) the fluctuating voltage, from 12.3 to 13.6 V maximum.

    I discovered that it behaved almost the same as before it was changed: when the car is still, A/C is on, the voltage is stable from 14.1 to 14.2 V. Immediately after I start steering (the car is still), the voltage fluctuates from 12.7 to 14.0 V

    This only happens when the car is still. If the car is rolling, the voltage is above 14.0 V.

    I attached the following videoclip for you to see what happens when I steer.

    http://www.youtube.com/watch?v=1BhHM95du0o

    Please tell me if you experience this issue. A testing on your own cars would be best.

    I used the hidden menu to see the voltages.

    for the last seconds of the clip you can see 14.1 V. That's when I stopped moving the steering wheel.

    Common issue unfortunately. Some are worse than others. I think on one model, the 1.9, there was a specific issue with the alternator that required it to be replaced under warranty.

    EDIT: I see that you have that engine so maybe you have that issue. There's info elsewhere on the forum as to what year/VIN no it affected.

    i have noticed my headlights dim when steering whilst stationary, but i understand it is due to the electro-hydraulic power steering. as i understand it, the power steering pump only activates when you steer & is not engine driven like some cars, so the drop in voltage is most likely due to the power steering pump working.

    hope that helps a bit.

    Yep it's an electric motor that draws a fair current.
    Now I need a turbo to keep up!

    I seem to get fluctuations purely on the centre screen. Never noticed the headlights dimming when standing still.

    I know it's an electric motor that steers the wheels, but is it normal to consume so much voltage?

    Duncan, I read the topic. According to it, my VIN number is well after the last number written over there in the GM bulletin. Theoretically my car's alternator should be without worries.

    Tomorrow night I'll be seeing an electrician to check my electrical system. If I find something wrong, I'll post it here. Until then, if any of you have the time, please check your voltages the way I did and write the results here.

    Okay, that's good then. In that case it's probably just normal then. I've never really noticed it on my car, but (many) others have reported quite a dimming of lights when turning the wheels when stationery - so it may be something that you just have to live with. As long as when you're driving it's not dimming that's the main thing!

    All I'm trying to do is look for a reason why my alternator's regulator broke twice in the last 2 months.

    Probably from the same batch of faulty units?
