i have a 2002 QX4 110,000 miles, does not turnover at all, there is a clicking sound when you turn on the overhead map light, and the light is very dim and flutters. the positive cable that connects to the battery had almost completely disentegrated, however i made it work(about a month ago)- but now the car does not start again- my guess is the battery is ok ..but just not getting a good connection...does anyone know of the right replacement for this positive cable, and why does this bluish, greenish stuff build up around the positive terminal...is that a sign that the battery is bad or something else? THanks for your replies.
