    Hello, so my alternator pooped itself, was a fun time getting it home. New alternator is $600+, 1. is getting it rebuilt a bad option? I assume I would still need to buy a new voltage regulator regardless. 2. Can I pop the car on ramps and remove it from the underside, or is through the top...

    New to the forum. Third owner of this fun 450SL. I have to replace the alternator. I believe the OEM was Bosch but not sure. Is Bosch a recommended/preferred replacement or is there another manufacturer preferred. Thanks.
  9. W210 E-Class
    I have a 2000 E430 that randomly doesn't start. Sometimes the lights will come on, sometimes it will look completely dead. I just went to a car battery specialist, and he says both my battery and alternator are in great condition. If I jump my car with an electric jump starter (one I plug into...

    First of, it is a 2002 CLK320 (W208) with 99,000 miles. I started getting the alternator/battery light to come on then go clear. I decided to do the obvious and order a regulator. I pulled the alternator and checked the brushes. They were good, but I noticed a very slight whir when I spun...

    Does anyone have experience replacing the alternator cable? I can't find a good diagram or part number and it looks like it it runs with the engine harness. Also there are no aftermarket parts for it. Any help would be appreciated.

    Hey guys, So yesterday my car had a little hiccup. The whining noise from the engine bay comes out and it follows the rpm, so if I give it gas the frequency of the whining noise also goes up. Also, my car shut off while I was driving it really hard. Maybe I pushed it to its limits? Here's the...

  17. X204 GLK-Class
    Hello- I recently had to replace my alternator in my 2011 GLK350. The odd thing at the time was it was saying the 'Aux battery' was low, which this vehicle does not have. I tore half of it apart looking as well as scoured the internet looking for this, only to come to the conclusion the...

    Hello all, I am writing this post in a concern about a bat/alt light in my 2004 C320 4matic. The car came with a 120amp Valeo alternator, and just recently it stopped charging the battery. We changed the brushes and regulator, and to no avail, it failed the test at oreillys and autozone, so it...
