It sounds like you have a short, the best way to find a short is to take off one battery cable and connect a 12 volt test light betweem tje cab;e you removed and the post it goes on. make sure that hood light bulb is removed and nothing else is trying to draw power. If test light comes on you have a short. If you do have a short pull one fuse at a time until light goes out. Once you have pulled a fuse and light does go out the problem is in that curcuit. Make sure you put back each fuse after you have pulled it and determined that it isn't that cucuit. Also most radios will pull power for the clock when key is off. Rcently I fixed a dodge caravan that the hood lights werent shutting off because the holder for the switch was cracked and the switch would push down inside of the holder and not shut off. The fix was easy I just took a twisty from off of a bread package and stripped off the material and wrapped the bare wire around where it was cracked and twisted it. Then you pull up the switch higher than it needs to be and close the hood and it will adjust itself. If it doesnt work the first time pull it up higher. Good LuckIt sounds like you have an excessive "Parasitic draw" problem. It is called parasitic because when the car is not running, certain components feed off the battery, such as the computer, clock etc. When other components like a dome light is left on, it will take more energy then the battery can supply in a short time draining the battery. If you are sure that everything is off, including hood light, dome light, glove box light, trunk light, then your best to take it into an independent repair shop and have them troubleshoot it.

How do you know if your alternator is out in a 2004 Ford Freestar?

I just went through this with my Windstar - stopped by my favorite Autozone and they did a pretty thorough electrical test, including the alternator and battery. Most of the auto parts stores offer free testing. Easiest thing to do is remove the positive connection to your battery if you Freestar stalls....Alternator is no good(just happened to me)


Why does the battery light stay on even after the alternator has replaced?

Find a volt meter, check the battery voltage with the engine stopped, it should be a around 12 V. Now start the engine and the voltage should be around 13.5 V. If the alternator isn't putting out about 13.5 (+/- .5 V) the replacment alternator could be bad or you might have a bad connection somewhere.


What to do about battery light staying on after staring up your Ford Escape Just put in a new battery and no change?

Same thing happened to me. Replaced the battery & the light went out for a couple weeks; after which it was back on again. This time I took it to the shop & they said the alternator was about to go. I didn't want to "fix" something that was "about to go" so I drove it for about 10 more days before the alternator stopped putting out enough juice to keep the car running or battery charged. Took the car back in & paid to have the alternator replaced. Guess they were right b/c it has worked just fine since. Good luck. It sounds like your alternator is about to go.

2000 Saturn LS tensioner seized and serpentine belt broke replaced all and will still not run?

This happened to me as well. Don't forget to re-charge the battery as well. Since the belt broke you probably can assume that the alternator stopped charging the battery at least for a moment.
