Just got back from the mechanic with the bad news about what is causing our little car to sound like it has a an electric motor. The bearings of the alternator are shot. It must be replaced.  We looked at the cost of a new one and I needed to sit down.  It is over $500! Please pray that God will open up another option.  I really detest solid state.  It was so much easier when you could buy a kit and rebuild your alternator.
