If the operator attempts to stop the engine incorrectly it may destroy the alternator diodes and the battery. A protective circuit is disclosed which keeps the alternator field connected to the battery until a signal such as the engine-oil pressure reports that the engine has stopped. The protective circuit is small and connects to existing engine control panels; it may also test itself without any risk of damaging the alternator or the battery.
