CLEANING TOWER INSERT
battery hold-down bolts properly tightened. Particu­
lar care should be taken to see that the top of the
battery is kept clean of acid film and dirt. When
cleaning batteries, wash first with a dilute ammonia
or soda solution to neutralize any acid present and
then flush off with clean water. Keep vent plugs tight
so that the neutralizing solution does not enter the
cell. The hold down bolts should be kept tight
enough to prevent the battery from shaking around
in its holder, but they should not be tightened to the
point where the battery case will be placed under a
severe strain.
To insure good contact, the battery cables should be
tight on the battery. If the battery cable terminals
are corroded, the cables should be cleaned
separately with a soda solution and wire brush.
If the battery has remained undercharged, check for
loose or defective fan belt, defective Delcotron, high
resistance in the charging circuit, oxidized regulator
contact points, or a low voltage setting.
If the battery has been using too much water, the
voltage output is too high.
