Warning
• Wear safety glasses when working near batteries.
• Keep batteries out of the reach of children.
• Never wear rings, metal watch bands or other items that may ground a live circuit.
• All lead-acid batteries generate hydrogen gas which is highly explosive and flammable. If ignited by a
spark or flame, the gas may explode violently causing spraying of acid, fragmentation of the battery,
and possible severe personal injuries, particularly to the eyes.
• Never cause sparks to occur or smoke near batteries that are charging or have been recently
charged. Keep sparks, flame and smoking materials away. Ventilate when charging or using in
enclosed area. Always shield eyes when working near a battery.
• Avoid battery acid. Batteries contain sulfuric acid. Antidote: EXTERNAL—In case of contact with acid,
flush immediately with water. INTERNAL—drink large quantities of water or milk. Follow with milk of
magnesia, beaten egg, or vegetable oil. Call physician immediately. DO NOT give fluids that would
induce vomiting. EYES—Flush with water for 15 minutes and get prompt medical attention.
• Never use booster batteries to start the engine or try to charge the battery if the electrolyte in the
battery is frozen.
• Charge batteries only in a well-ventilated area. Always be sure battery chargers are OFF when
connecting to or disconnecting from batteries.
• See Delco Remy Service Bulletin 1B115 and 1B-116 for additional safety information and procedures.
IMPORTANT: The diodes in the alternator function as one-way valves and the transistors in the voltage
regulator operate as fast switches. Both are accurate and sensitive. They do not wear out and cannot be
adjusted, but because they are sensitive to voltage changes and high temperature, the following precautions
are vital to prevent them from being destroyed:
• Disconnect the ground cable first when you disconnect the battery cables from the battery; connect
the ground cable last when you connect the battery cables to the battery.
• Always connect POSITIVE TO POSITIVE, NEGATIVE TO NEGATIVE.
• DO NOT disconnect the battery while the engine is running. This will cause a voltage surge in the
alternator charging system that will immediately ruin the diodes or transistors.
• DO NOT disconnect a lead without first stopping the engine and turning all electrical switches to the
OFF position.
• DO NOT cause a short circuit by connecting leads to incorrect terminals. Always identify a lead to its
correct terminal. A short circuit or wrong connection giving reverse polarity will immediately and
permanently ruin transistors and diodes.
• DO NOT connect a battery into the system without checking for correct polarity and voltage.
• DO NOT “flash” connections to check for current flow. No matter how brief the contact the transistors
may be ruined.
• If a battery-caused cranking complaint exists with a clear or light yellow indication, replace the
battery. In this case the charging system should be checked; refer to charging system instructions in
this manual. Excessive over-charging, broken case or tipping the battery over 45° on its side will
result in loss of electrolyte level.
