Ok, So I bought a 1991 164L and am very happy with it. I bought it knowing that I would need to spend some serious time figuring out Alfa problems. I know Alfa's are known for oil leaks and electrical issues. Overall my car is in awesome shape, but I have one issue I can't figure out. The "anti lock" light is lit on the dashboard, and I have no clue where to look for the fault. Some possibilities that I came up with 1. the car came with 15inch rims, the previous owner put 17 inch rims on. 2. the brake fluid reservoir has one wire that is broken. 3. The steering rack was replaced, and in the process broke the odometer gear so odometer does not work. Can someone please tell me if any of these are real possibilities for causing the light to come on. If not, where should I look to diagnose the fault. This seems to be a rather pesky issue, and I am out of ideas. Any help would be appreciated. Thanks
