Figure 5-290. Battery Voltage Test
(2) Test the battery with a volt-ohmmeter.
(a) Connect the positive (+) meter lead to the positive (+) battery pole.
(b) Connect the negative (-) meter lead to the negative (-) battery pole and set the meter on volts.
(c) If the meter reads 11.5 to 12 volts the battery is ok.
(d) If the meter reads less than 11.5 volts, check the specific gravity of the electrolyte.
Figure 5-291. Specific Gravity Test
(3) Test the specific gravity of the electrolyte in the battery. Use a hydrometer.
CAUTION
The electrolyte level must be kept above the top of the battery plates.
DO NOT overfill the battery. The electrolyte should not overflow onto the battery when the cell
caps are set in the battery.
