I went ahead and stuck in a new alternator, battery, and alternator belts. Batt light goes on with the key and goes of instantly when the engine is started. However, the glow plug light was awfully dim and I'm getting 12.3V at the battery at idle. The brake wear indicator light is still not coming on. Now what? Ground issues?
