Having problems with your 2003 Ford Windstar ?
2003 Ford Windstar won't start
\015 Vehicle had odd flickering interior lights since we bought it a year ago, was annoying but nothing big. Now the battery keeps draining (brand new battery) and the van won't start without a jump. It will stay running but if you let it sit for more than an hour it won't start again.\015
Either your battery has failed or the alternator/ regulator/rectifier has. With the engine running, check the DC voltage at the battery terminals it should be above 13 volts but below 15. If it is outside this range then your alternator or regulator has failed. This is the most likely. If it is in this range then you need a new battery. As you have changed the battery it may need changing again if the rectifier has failed. but hope it is the alternator giving no output.
