Battery
Every 10,000 miles check the electrolyte level of each cell and the general condition of the battery. Maintain the electrolyte level to the base of each vent well. The make-up water must be one of the following (in order of preference):1. Distilled water.2. Odorless, tasteless drinking water.3. Iron free water.4. Any available water.
Never add acid or electrolyte.
CLEANING BATTERY: Mix a weak solution of baking soda and water. Apply the solution with a soft bristle brush. Be careful not to get cleaning solution into the battery.Thoroughly rinse the battery and battery tray with clean water. Apply grease to the battery cable clamps and terminals and to all threads.
CLEANING BATTERY TERMINALSTESTING THE ELECTROLYTE SOLUTION: The general condition of a battery can be determined by measuring the specific gravity of the electrolyte solution and adjusting the reading to 80°F (27°C). If the electrolyte level is too low to allow taking a hydrometer reading, add make-up water to the correct level and then charge the battery 2 to 4 hours before taking a reading.
TESTING ELECTROLYTE SOLUTION1. Insert the hydrometer into a cell. Fill the hydrometer barrel while holding it vertically. The float must not drag on the wall of the barrel.2. Read the hydrometer: 1.250 or above - fully charged battery cell1.250-1.225 - full to half charged battery cell1.225-1.150 - half to low charged battery cellBelow 1.150 - dead cell1.000 - water3. Test each cell in the same manner.4. If there is more than .050 (50 gravity points) variation between the highest and lowest reading, the battery should be replaced.5. Adjust the readings to 80°F (27°C). a. For every 10F° (5,5C°) the electrolyte temperature is above 80°F (27°C), add .004 (4 gravity points) to the specific gravity readings.b. For every 10F° (5,5C°) the electrolyte temperature is below 80°F (27°C), subtract .004 (4 gravity points) from the specific gravity reading.The corrected reading is of most importance during cold weather when the hydrometer reading is always corrected to a lower specific gravity reading. A low reading signifies the battery has less available power to crank the engine and that booster batteries may be required.VOLTAGE TEST (AFTER LOAD): A load test should be made on a battery that discharges very rapidly when in use. To do this apply a resistance of three times the ampere/hour rating of the battery across the battery main terminals. Allow the resistance to discharge the battery for 15 seconds and immediately test the battery voltage. A 6 volt battery in good condition will test 4.5 volts; a 12 volt battery in good condition will test 9 volts and a 24 volt battery will test 18 volts.Starting System
Use a D.C. voltmeter to locate starting system components which do not function.Turn the key switch ON. Turn the HEAT-START switch to the START position. Starting motor solenoid operation is audible as the starter motor pinion engages with the ring gear on the engine flywheel. The solenoid operation should also close the electric circuit to the starting motor. Attach one voltmeter lead to the
