Hi I've just recently been given an Au3 wagon in excellent condition for the price. In process of getting roadworthy which I didn't think would take much at all. Only seems to have a hey wire instrument cluster( checked all earths and removed cluster and still tacho is off the clock, speedo works intermittently, temp and fuel off the dial too)! Now just noticed everytime I hit the horn it's popping the 15amp fuse straight away. Can anybody pls help me with both of these issues. Thanks in advance!!
