Hydrometer Calibration, Continued:
Most hydrometers are calibrated to read correctly at 80°F. The readings obtained as described above must
be corrected for temperature. For each 10°F above 80°F, add .004 to the reading. For each 10°F below 80°F,
subtract .004 from the reading.
Interpreting Results of the Hydrometer Test
The approximate state of charge can be determined from the following table:
If the difference between the cells is .020 or more, the low cell should be suspected. It may require a catch-
up charge or it may be a weak cell. When the variations between cells reach .050 or more, the battery should
be replaced (See Caution on page 129).
VOLTAGE TEST
See Testing the Battery, Page 87.
Load Test
1. Using a 160 ampere load tester, connect the load tester to the battery posts.
2. Read the battery voltage after the load tester has been on the battery for 15 seconds. Compare the
battery’s voltage reading with the table below. Make sure you have the correct ambient temperature.
REMOVING THE BATTERY
1. Remove the seat from the rear body.
2. Disconnect the air hose that is clamped to the carburetor. Remove the retention strap and lift the intake
expansion chamber out of the vehicle. Make sure the O-ring is kept with the intake expansion chamber.
3. Disconnect the battery wires as shown (Figure 12-1, Page 82).
4. Remove the two locknuts and washers and lift the hold-down off of the battery.
5. Use a battery strap to lift the battery out of the vehicle (See DANGER and WARNING on Page 131).
