We have a Excel that ran great when it was driven everyday, but now that I bought my wife a new Santa Fe, the Excel does not get driven. When it was driven as a primary car we had great luck with it, but now I can not keep a charge on the battery, bought a new battery and I try to keep the engine running by driving it a couple time a month for a few miles, but the battery continue going dead so now I think it may be a short, but I can find it, doe anyone have a similar problem that they have been successful it correcting?
