My '95 Yukon XL has super low miles & is in excellent shape, except the brand-new battery keeps going dead on me. Have had it towed to multiple shops. They say the alternator is in great shape. We've cut off all superfluous electricity drainers, like car phone & vanlty mirror lights. The latest mechanic seems absolutely stumped. I love my Yukon & don't want to get rid of it! Any suggestions?
