A lit charging light, dropping voltage at idle, or an alternator whining in the bearings are classic signs that the charging system needs a look. Which alternator fits is determined by the engine and version: early B18/B20 with a carburetor use one variant, while the fuel-injected B20E/F and B30E/F require a different alternator.
