In trying to figure out why my console ammeter doesn't work I noticed that the fuse in the orange wire is blown, can anyone tell me what this wire does and what these boxes are under the left front fender? the large gauge red wire in the first picture is taped off on the end and hanging freely. In the second picture does anyone know what the red and yellow wire are that attach to this junction block behind the brake booster? the car runs fine and seems to charge normally. thanks in advance!
