SERIES 60 ON-HIGHWAY ENGINE OPERATOR'S GUIDE Item 19 Oil Pressure Under normal operation, oil pressure is noted each time the engine is started. In the event the equipment has warning lights rather than pressure indicators, the pressure should be checked and recorded every 60,000 miles (96,000 km) for vehicle engines. Battery Explosion and Acid Burn To avoid injury from battery explosion or contact with battery acid, work in a well ventilated area, wear protective clothing, and avoid sparks or flames near the battery. If you come in contact with battery acid: Item 20 Battery-Charging Alternator Flush your skin with water. Precautions must be taken when working on or around the alternator.
The diodes and transistors in the alternator circuit are very sensitive and can be easily destroyed. Apply baking soda or lime to help neutralize the acid. Flush your eyes with water. To avoid equipment damage, pay attention to the following: Get medical attention immediately. Avoid grounding the output terminal. Grounding an alternator's output wire or terminal (which is always “hot,” regardless of whether or not the engine is running) and accidentally reversing the battery polarity will result in equipment damage. Never disconnect the battery while the alternator is operating. Disconnecting the battery can result in damage to the battery diodes.
In applications which have two (2) sets of batteries, switching from one set to the other while the engine is running will momentarily disconnect the batteries. Do not reverse battery connections. If a booster battery is to be used, batteries must be connected correctly (negative to negative, positive to positive). Never use a fast charger with the batteries connected or as a booster for battery output.
