Question about 2001 Mercedes-Benz C-Class

1 Answer

While driving this afternoon, my 2001 C-320 displayed that my battery/alternator needed immediate repair (or something to this effect). Within minutes, it started to overheat, reaching 120 degrees Celcius within a matter of minutes. I pulled over and let the car cool down for about 30 minutes. When I restarted the car and pulled off the highway into a parking lot, the same message about the battery/alternator came on and the power steering was gone. I popped open the hood and discovered that a rather large rubber belt (serpentinebelt I think) was no longer attached to the engine. Now it is sitting in my front seat! Help! What do I do next??

You need to get the belt back on. You can't drive the car without it. Also you need to find out if the belt was just old and broke or if a part went bad, like an idler pulley or a tensioner , and replace it as well so the new belt will stay on.

    Thank you for your advice! The belt is still in tact (I didn't examine it too closely but it is still in one piece) so I'll have to check the other possible culprits you mentioned. Any idea how difficult it is to repair? Or how much I should expect to pay for someone else to do it?
    Thanks again!!

    Not sure how easy it is to put back on, on that model. As far as how much, not much to put the belt back on, maybe 35 dollars. But if something broke that made the belt come off, I don't know how much it is unless I know what went bad.

I would stop using the car immediately. You don't provide details of what the "popping" sound sounds like (mini explosions? sparking?) but from the fact the battery (warning) light is on, there is something wrong with the charging system, perhaps a failed capacitor in the alternator. The popping sound could be from arching within the alternator circuit, and the high currents involved could cause a fire.

My 2009 Chevy Malibu just had a new battery put in within the last 60 days. Then I needed a new transmission. Got it fixed. Today my battery light comes on and stays on. What is this?

The light means that your battery is not being charged properly. It could be that when the transmission was replaced, they alternator belt was not put in properly or tight enough. I'd do the following:
1. Check battery connections to make sure they are clean and tight.
2. Check the drive belt to the alternator. It should be tight and not slipping.
3. If neither of the above is the problem, fully charge the battery with a battery charger so you can drive it for a while. Don't drive it without charging or you may get stranded. Don't let the battery run all the way down either or it may ruin it.
3. Check alternator output by driving to a nearby auto store or the place you had it repaired. They usually can check your charging system for free. The alternator could have decided to malfunction, although it's pretty new.
Good luck...

I have a 2003 ford focus wagon second hand. My battery died out and I thought the alternator was the problem. Brought my car to an alternator repair shop and they said the alternator is still good. I ended...

Lead acid batteries don't like being discharged flat, and it could now be damaged and unable to hold a charge. It does sound as though the voltage regulator part of the alternator is allowing discharge to ground when it should not. You would seem to have a good warranty claim on the battery given they did check the alternator and pronounce it OK.

Indicator symbol for battery lighted up twice for a few seconds

Sounds like your alternator is going out. Here is a simple test: Turn your car on. With engine running, disconnect the positive side of the battery, making sure it does not touch anything metal. Keep wipers, radio, lights, etc off. If the car dies within about 3 minutes, then your alternator is bad. Reconnect the battery and head to the shop using as little as possible from the battery, or you may end up on the side of the road.

First check the alternator drive/serpentine belt and make sure it is tight and not worn out. Replace it if it is cracked or glazed. Clean the battery cables and battery posts. With a voltmeter check the voltage at the battery with the engine running. If you have less than 13.5 volts the alternator needs replacing.

It turned out the ground wire to the battery was loose, Evidently, it loosened up when driving so mimiced the earlier symptoms because it connection was sporadic. I hooked up to a computer to verify after connection tightened and it came away with no errors or problems.

Tricky ... Was the alternator replaced with a 2nd hand one or a new one?

A defective alternator can allow the battery to discharge within a few minutes (the diodes in the rear of the alternator can burn out and cause the problem. The diode pack can be replaced). When this happens recharging the battery only replaces the power in the battery - which drains straight back to earth via the alternator, flattening the battery again - often within a couple of minutes or less.

Does the battery lose its charge when the car is standing or just when the engine is fired up?
If the battery loses its charge overnight, try disconnecting the wiring from the rear of the alternator (also look at the electrical connector that fits into the back of the alternator - look for melting/burning marks which suggest something may be amiss inside the alternator).

Let the car stand overnight with the alternator wires disconnected. Will it start up ok and drive (with the alternator wires still disconnected) the next morning?

You could also try just disconnecting the alternator wires, firing up the car and then driving it -
If the car drives ok without dying out and gets further down the street than it usually does, then it probably is the alternator at fault. The car should drive until the battery drains and has insufficient power to trigger the ignition. You certainly would get further down the street with a charged battery and disconnected alternator than you currently do.

It does sound as though you've had an alternator fault to begin with. If it has been replaced with a 2nd hand unit that unit may also be faulty. Rather than replace parts in desperation, visit an auto electrician's - within a few minutes they will be able to test the battery/alternator output and also identify where the lost current is going. It will be cheaper in the long run to have an auto electrician look at the charging system. It only takes a few minutes.
