i had them burn out on the back of mine - the copper had gone all black and fooked on the two main ones that go from the battery pos lug to the main fusebox - had to chop them back, and solder new tails on them both of about 100mm to get back to decent copper - i think someonw at some point had had the battery on cgarge left on the car and the acid had bubbled all over the top of the battery, cos thhose wires were manky as were the inside of the main cooling fans relay right next to the battery.
