I forgot... Take a look at your build sheet. Don't look at the last and the line before it, they are just build codes for the assembly line. Take a look at the upper lines, you can see that there are boxes that have a description and below them, a number. For example, take a look in the center where the line reads FLEET ITEMS, you will see below a printed number : "2". Look over it, you can see a numbers which says "62", add the printed "2" as a text, so it says : 622 ("62" plus the printed "2"). Look over the option code list and you can see that your came with a 48 amp battery from factory, doesn't that line over the "62" read battery ?
