Figure 5-130. Battery Voltage Test
Check the battery voltage. Use a volt-ohmmeter.
Undo retainer strap and remove battery box cover.
Connect the positive (+) meter lead to the positive (+) battery terminal and the negative (-) meter
lead to the negative (-) battery terminal.
If the meter reads between 11.5 and 12 volts, the battery is ok. Go to Step 8.
If the meter reads less than 11.5 volts, go to Step 9c.
Check the electrolyte in the battery. Use a hydrometer to check the specific gravity.
The electrolyte level must be kept above the plates in the battery.
DO NOT overfill the battery. The electrolyte should not overflow onto the battery cover when the
cell covers are placed over the cells.
