ELECTRICAL SYSTEM • Battery acid that may spill during charging should be washed off with a solution of warm water and baking soda to neutralize the acid. If you accidentally get acid in your eyes or on your skin, immediately rinse with cold water for several minutes and call a doctor. • Do not charge a frozen battery; allow it to thaw out first. And always allow the battery to thaw gradually— do not apply direct heat. Gas trapped in the ice may cause an explosion. • Never use a fast charger as a booster to start the engine. This can seriously damage sensitive electronic components such as relays, radio, etc., as well as the battery charger. Fast charging a battery is dangerous and should only be attempted by a competent mechanic with the proper equipment. Slow Battery Charging NOTE: Follow the instructions that come with your battery charger. • It is not necessary to remove the battery from the compartment. PREVENTIVE MAINTENANCE WARNING! Charger cables must be connected positive to positive (+ to +) and negative to negative (– to –). If connected improperly, batteries could explode causing death or serious personal injury. • Always make sure the battery charger is OFF before connecting or disconnecting the cable clamps. To reduce the danger of explosions and resulting death or serious personal injury, do not connect or disconnect charger cables while the charger is operating. 1. Make sure the electrolyte level in each cell is between the “MIN” and “MAX” marks. If the fluid level is below the “MIN” mark, correct the condition. 2. Disconnect the battery cables. 3. Connect charger cables. 4. Start charging the battery at a rate not over 6 amperes. Normally, a battery should be charged at no more than 10 percent of its rated capacity. 5. After charging, turn OFF charger and disconnect charger cables. – 222 – Y53-6033 Regional Haul (R05/10)

Electrical and Alternator Precautions<br />

Take the following precautions to avoid burning out alternator<br />

diodes:<br />

• Do not start the engine with alternator disconnected<br />

(connections removed) from the circuit.<br />

• Before welding, disconnect all electronic connections<br />

to the vehicle batteries.<br />

• Remove battery power cable and insulate it from the<br />

vehicle.<br />

• Do not run the engine with the batteries disconnected.<br />

• Do not disconnect the battery cables or alternator<br />

connection cables with the engine running.<br />

• Never turn the ignition switch to the IGN & START<br />

position with the engine running.<br />

• When charging the battery (installed in the vehicle)<br />

disconnect the battery cables.<br />

• Do not reverse the cables of the alternator, starter<br />

motor, or battery.<br />

• Do not polarize the alternator. The alternator should<br />

not be polarized like a generator. To ensure correct<br />

polarity, use a test lamp or a voltmeter.<br />
