ENGINE ARRANGEMENT 6N1148 - Caterpillar

Note: This engine is equipped with an alternator circuit breaker. Note the location of the alternator circuit breaker for your particular application. If the alternator circuit breaker trips, you will need to reset the breaker in order for the charging system to operate. Refer to the information that is provided by the OEM for more information.Caterpillar recommends a scheduled inspection of the alternator. Inspect the alternator for loose connections and proper battery charging. Inspect the ammeter (if equipped) during engine operation in order to ensure proper battery performance and/or proper performance of the electrical system. Make repairs, as required. Refer to the Service Manual.Check the alternator and the battery charger for proper operation. If the batteries are properly charged, the ammeter reading should be very near zero. All batteries should be kept charged. The batteries should be kept warm because temperature affects the cranking power. If the battery is too cold, the battery will not crank the engine. The battery will not crank the engine, even if the engine is warm. When the engine is not run for long periods of time or if the engine is run for short periods, the batteries may not fully charge. A battery with a low charge will freeze more easily than a battery with a full charge.
