I've got no hard evidence, but I believe that most AMM failures are due to corrosion on the circuit board. There is also a hybrid circuit on the board that may be the failure point. A hybrid circuit is a custom integrated circuit made up of parts of other ICs plus some discrete (resistors and capacitors) components. Not the sort of thing that even highly sophisticated home-brew electronics types are equipped to deal with.
If you felt like messing about, there really isn't a big downside. That's the idea of a hobby or a project - you'll spend more than it's worth, not counting the fun factor. But I agreee with Anders - if you want to get the car working, get a quality rebuilt and leave the electronics to others.
