    Question Cultus Alternator/Generator Load Problem

    I have a Cultus VXR 2006 which i bought just 4-5 months back. The problem that I am facing is that when I turn on the AC at night with the headlights on, the alternator/generator doesn't take the load and stop charging. It works just fine when I use AC in afternoon without headlights. I have got it checked from an electrician and he is saying your generator is fine, but its not taking the load of AC+Headlights. He is saying that you can replace your generator with a heavy one of suzuki baleno and this problem will be solved. He is saying that its will cost me 4000 for the kabli baleno generator with the fitting and everything after taking my generator. So I have 2 questions:

    Is it ok to put a baleno generator in cultus?
    Is he asking the right price for the generator replacement?

    Please answer my questions asap.

    your electrician is a dumbass for saying "load nahi le raha" - check the grounding on the alternator and then test the voltage, ask him to full field it, the full field test confirms that the alternator, stator, rotor, carbon brushes and diode pack is good but the voltage regulator is bad, that can be replaced separately for a lower cost than the whole alternator.

    they don't know about the full field test...i asked one electrician and he pretended (failed badly) that he knew it

    Also the poster should check all grounds, the main ground etc. I am sure this is a problem of terminals or grounding. The car is not that old for the alternator to go bad.

    yes it is usually the grounds that go bad, our electricians love to replace parts, perfectly good parts.

    to test the alternator, you need to connect a voltmeter to battery terminals.

    it should be 14 +. even if lights and ac are on. if it drops, pull the throttle to increase rpm, if it increases back to normal, good, if not, check the grounding.

    for diagnosis, add a wire straight to alternator body from battery negative.

    to check charging wire, one probe of voltmeter on alternator positive terminal (it is the one where charging wire is bolted on). and the other probe on battery negative. if it shows more voltage this way, compared to both probes at battery terminal, then there is a bad connection somewhere.

    you only need to buy a multimeter that costs max 1000 rs

    full fielding the alternator is easy, all it requires is a small thin screwdriver and someone to read the voltmeter which you connected to the battery.

    there is a hole in the back case of the alternator, that hole aims straight to the mounting screw of the carbon brush pack where it connects to the regulator. If you take you screwdriver and touch that screw through the hole - you effectively dead ground the alternator, It will then start charging at maximum. You should see the voltage shoot to 15V or higher.

    If you do - then check the ground connections - if you find grounding good then replace the voltage regulator.

    The story of "load nahi le raha" is the oldest joke in the book. They use it to make extra money.

    thats real sad. Pretending to know is worse than not knowing.

    yep, imo it would be better to admit it and learn, i would do that.

    @siraj, full field means that the alternator voltage regulator gets bypassed, it produces as much as it can, at that rpm.
