Disconnect the negative cable and connect (insert) an ammeter between the battery and the battery cable. Remove the fuses one by one and see which causes the current draw to drop.

What can cause the alternator cable drawing current from the battery on a 2003 beetle. the alternator has already been changed.?

Disconnect the cable from the alternator and see if that stops the draw. If it does, the alternator may be defective. Otherwise there may be something else drawing current.

Why wont your battery light go off when you changed your alternator and battery in your 99 mercury cougar?

Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alternator belt. If the battery and alt test ok than check the connections to the alternator and battery. You may also have a battery drain (something that is staying on and killing the battery)

Why does automatic car stop running when battery is disconnected?

Why are you disconnecting the battery with the engine running? Never mind, you've probably already figured this out by now, but there's a good chance your alternator is fried and your spark plugs are running on battery power. Get your alternator checked out. New ones aren't that expensive (approx. $50) and can be changed by anyone handy with tools.

I just changed the battery in my car and put the battery cables on backwards now the battery won't charge I tried a different battery and still wont work. Could I have damaged the alternator?

when you reverse connect a battery there is a good chance you will blow the main fuse this will protect the car from more damage but usually stops the battery for been charged as well... check and change the main fuse or fuseable link The alternator probably already was bad before you put the battery in.

When you drive your 2000 elantra you notice that smoke comes out of the battery top vent you changed the battery and this is still going on does anyone know what could be the problem?

The alternator is probably over-charging the battery. Replace the alternator if the voltage at the battery terminals is over 15V when the engine is running.

Why did your new battery die after you changed the starter It started once ran for ten mins Went to start it an hour later battery was dead for your 98 Grand Prix SE?

Your alternator is not charging the battery like it's suppossed to or the battery cables might be corroded and may need to be changed or cleaned, but the good news is autozone can recharge your new battery back up for free. Also make sure after you change the alternator and clean the battery cables and put the battery back in have the guy at auto zone test the new alternator before you buy it to make sure it works properly.


How do you change an alternator on a 1995 Volvo 960?

The alternator on a 1995 Volvo 960 is changed by disconnecting the negative battery post, removing the alternator wiring harness, loosening the retaining bolts, and taking the belt off. The alternator can then be completely unbolted and a new alternator put in its place.


Whats wrong changed starter and alternator on 1998 Bonneville still won't start?

Did you replace the battery? I am trying to determine why you changed out the alternator which charges the battery, and the starter which only starts the car. The 2 are only related through the battery. One system does not rely on the other. As you drive the alternator puts a charge out to recharge and maintain your battery. Your starter only engages when you turn the key to start the car and this draws a lot of voltage from your battery. Try to explain in better detail: Like the car will try to start, it will start but won't keep running or the car won't even turn over, or I am getting a clicking sound. The better you describe the situation the easier it is to get you pointed in the right direction


You changed alternator 3x this year what else could the problem be?

Get the battery load tested. A bad battery will quickly destroy a new alternator. Also check for a bad ground from the battery minus pole to the chassis and then to the transmission, then to the engine, then to the alternator body. Use a DVOM and measure resistance in the preceding steps to determine if any segment has greater than 0.001 ohms of resistance. Some techs like to use voltage drop as a test, I am partial to resistance readings. In the end they accomplish the same thing.


Why does my diesel Nissan Terrano always die so every time i have to jump start.?

Your battery is not charging. It is either due to a faulty battery or a faulty alternator. Get it changed.


Changed starter in 96 cavalier why is battery losing charge when car is driven?

Most likely, your starter isn't the problem. You may have a bad alternator. Usually when your battery doesn't recharge properly it's an issue with the alternator. Have a mechanic inspect the alternator if you're not comfortable doing it yourself. If it is an issue with the alternator, it's a pretty cheap fix.
