Abstract
The protection system includes an over-temperature warning lamp in addition to the usual charge indicator lamp. Both lamps light at ignition as a test, then both go out. If the alternator should fail, both lamps again light. If the alternator overheats, only the warning lamp is lighted and current to the field coil is removed.
