ITEM TO BE INSPECTED
The 6TN and/or the 6TL batteries will perform properly in hot
weather as long as electrolyte levels are carefully monitored. If
the electrolyte expands and causes the level to rise, some fluid
must be removed.
If the level becomes too low due to
evaporation, distilled water may be used to obtain the proper
level. A good grade of drinking water (excluding mineral waters)
may be used if distilled water is not available.
Check battery cable connections and mounting for tightness (figure 3-10).
Check electrolyte level. Correct level is 3/8 inch (9.5 mm) above plates.
Check filler cap vent holes for obstructions.
Check electrolyte with hydrometer every week. Fully charged battery will
indicate specific gravity of 1.250 to 1.280 at 80 F (26.7 C). Remove any
corrosion from battery terminals and lubricate.
