[QUOTE="Richard Johns, post: 1039957, member: 68192"] Bad alternator diodes may be the most likely cause. As an example, my Sport Trac has a high output alternator and if three diodes are bad, the alternator light most likely illuminate and your battery will most likely lose its charge overnight. Bad diodes allow battery drain through the altenator; in other words, the diodes are to only allow electrical flow one way - to charge the battery - not both. However, if only two or one is bad, your alternator light may not illuminate and a volt meter may also reflect it to be charging, but in fact the two or one faulty diodes will cause the battery to drain and go dead over a few days time. Repeated cycling allowing AC to enter the battery - what the diodes prevent - will kill the battery cells. I've had four batteries over the past couple years - it was illuminating discovery! [/QUOTE]
