Car battery dead other weird symptoms? related? PLEASE help!!!?

I'm with the consensus, it's the alternator. If the battery light came on it was because the alternator was failing. The radio, the weird things the engine did - are all likely due to low voltages going to the computer that controls all that stuff. It was probably making some irrational decisions (as when a person is suffering a lack of oxygen).

Charging the battery will be a temporary fix AND you run the risk of causing permanent problems with the computer. It's better to get the car fixed as soon as you can. Meanwhile, don't miss work because of it. Employers tend to look at excuses as sounding like excuses. Just make other arrangements to get to work for the rest of the week and change the alternator this next weekend. OR, if you can do it yourself now, remove the current alternator and take it to your local auto parts store. Many offer free testing of them. They'll tell you if it's really the problem. If so, you're in the right place to pick up a replacement alternator.

They're not that hard to change. First you loosen the belt off the alternator. Then you loosen the bolts holding the alternator on - usually just two, one big long one and one that connects to a bracket that allows adjustment of the tension of the belt (if your car doesn't have an automatic tensioner). And there's going to be a plug and one big wire attached with a nut. BUT BEFORE YOU BEGIN, disconnect the negative terminal of the battery. Even if it's dead, still, better safe than sorry. Once the battery is disconnected you can remove the alternator. Most common size bolts for that are 12 mm & either 13 or 14 mm (the bigger bolt).

Pull the plug off the alternator then disconnect the big red wire. Save the nuts, you might need them. But typically new or rebuilt alternators come with new nuts. Then remove the alternator. Putting everything back in is just the opposite of removal. Mount the alternator, hook up the red wire, plug in the plug, re-install the belt.

This is also a good time to take a good look at the belt. If it shows any signs of cracks in the ribs or shows strings along the edge then it's time to replace the belt. Best to do it at the same time. And it's not that expensive, so why not do it all at once and save yourself the hassle of having to disconnect things again.

Hope this helps.

Car Battery Dead Symptoms

The vehicle would not start. If it dies whilst running, it seems like an alternator crisis. If the alternator goes, it won't be able to recharge the battery while running, and accordingly, it'll die. You also could want to examine the wiring to ensure that all wires from the alternator to the battery are properly and entirely connected. While the auto is walking, the alternator must be recharging the battery. This absolutely isn't happening.

Your alternator is bad. Charging the battery will only work for a short time till it dies again.

yes sign of alternator gone not big job to fit new one expensive .one you have might only need new brushes so get it checked out if you have the time ,ok def alternator for sure .all the best .
