over posts and into top of jar, pressing them
down until they rest firmly on top of plate straps. See that covers
are perfectly level and that vent tubes are perpendicular and all at
same height above the plates.
8. Heat compound just hot enough so that it will flow. Pour first
layer about one quarter inch thick, being careful to cover entire jar
cover. Take a soft flame and seal compound around edges of jar and
onto posts.
9. Now proceed to burn on top connectors. Cell connectors need only be
cleaned in hole left by post, and top of each end.
10. While burning in cell connectors the first layer of compound will
have cooled sufficiently to permit the second layer to be applied.
This should be done immediately after burning on connectors and while
they are still hot. Also heat the terminal posts, as compound will
adhere to hot lead more readily than to cold.
Start second layer of compound by pouring it over cell connectors and
terminal posts, first filling in with sufficient compound to bring
level just above the tops of jars. Apply flame, sealing around edges
of wood case, being particularly careful to properly seal terminal
posts. Let this layer cool thoroughly before applying third layer.
11. The third layer of compound should be applied in the same way as
second layer, pouring on connectors and terminal posts first, and
filling in to the level of top of wood ease. The spaces between bars
of cell connectors will fill and flow over properly if second layer
has been allowed to cool and if cell connectors have not been burned
up too high. In sealing last layer with flame, care should be taken
not to play flame on compound too long as this hardens and burns the
compound. Burned compound has no flexibility and will crack readily in
service, thus causing the battery to become a "slopper." In pouring
compound be sure to have battery setting level so that compound will
come up even on all edges of case. Do not move battery after pouring
last layer until thoroughly cool.
Before installing battery on car be sure that no compound, etc., has
been allowed to get onto taper of terminal post, as this will make a
poor connection. If this has happened, clean with medium grade
sandpaper.
