VALVE AS-DIGN 4538752 - Caterpillar

recommends a scheduled inspection of the battery charging alternator. Inspect the alternator for loose connections and proper battery charging. Inspect the ammeter (if equipped) during engine operation to ensure proper battery performance and/or proper performance of the electrical system. Make repairs, as required.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 not be allowed to get too cold, as temperature affects the cranking power. If the battery is too cold, the battery will not crank the engine. A battery that is too cold will not crank the engine, even if the engine is warm. When the engine is not run for long periods of time or runs only 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.
