    I saved a 2005 from the repo yard, it had been sitting about a year so I got it at a good price, I got her going but the dash had the red triangle so I pulled the battery pack..all the cells but one tested between 7.6 and 7.8, one was 6.54 so I replaced it and it seems to be running OK now, no warning lights on the dash...all the negitive terminals have a lot of corosion on them that I cleaned off and the thick negtive cable is black on the ends....Im guessing Ill need a new harness soon or is this normal?
    Thanks :cool:

    Cleaning them in a mild acid solution such as vinegar or phosphoric acid (alloy wheel cleaner) the same for the terminals reassemble and apply a thin coat of sealer.
