Thank you for your reply, pizzaguy. I, too, have never known a main fuse to blow on ANY car I've owned. If that is indeed the problem, I assume it means that something on the car drew more than 200 amps! If the main fuse has blown, I'm reluctant to replace that fuse without first finding what caused the fault. Is it common for those fuses to just fail in time? The car is 12 years old, after all.
