the black lead goes from under the engine from other electrical wires to the (+) sign. (this lead is in a plastic casing)
is this normal??
This is normal. The (-) sign on the battery connected to the chassis means that the car is negative earth. The colour means nothing! though it would make more sense if Red indicated Positive and Black negative. It's like assuming that just cos the other driver is indicating left, (s)he is going to turn left - it just proves that the bulb hasn't blown!
