Been in the shop for 2 days - battery is good. Got up this am and the battery was dead again. Something is draining the battery. They dealership said the scraped paint off of a connector and thought it would fix the problem - IT DID NOT!

Help - any suggestions - it is a hybrid.

Are the Hybrids baterries 10 year 100,000 mile warranteed? Hybrids are dangerous to work on if you dont have the technical training, Fire depts, get traind to cut certain cable so their men dont get electrocuted, Probably not the answer you want, but I recommend you let Ford find the "Parasitic drain" A short can be ANYWHERE in the electrical system, or even inside the battery. Here's how to find the circuit involved. Get an analog voltmeter remove the negative battery cable, attach the Black lead to the battery post, Red lead to cable end, then pull fuses one at a time, make sure there are no accessories or lights in the on position, Key off! Close the door have someone in the car, pull fuses one at a time after each fuse check meter, when you pull the fuse for the bad curcuit, the meter will drop to 1 volt or so. Check all fuses, even under the hood. If meter does not drop, remove the battery connection from the alternator, if it drops now, the diodes are bad in the alternator. Put the fuse back in were it goes as you go so you don't forget which fuse goes were! Wait several minutes after hooking up the meter before pulling fuses, test with a good battery!
