rag wet with gasoline.

2. Drilling Off the Connectors and Terminals. When you have cleaned
the outside of the battery as thoroughly as possible, set the battery
on the floor near your work bench. Make a sketch of the top of the
battery, showing the exact arrangement of the terminals and
connectors. This sketch should be made on the tag which is tied to the
battery. Tic this tag on the handle near the negative terminal of the
battery or tack it to the ease. Then drill down over the Center of the
posts. For this you will need a large brace with a heavy chuck, a
drill the same size as the post (the part that goes down into the
battery), a large screw driver, a center punch, and a hammer.

[Fig. 191 Drilling post and cell connector]

With the center punch, mark the exact centers of the tops of the posts
and connectors. Then drill down about half way through the connectors
and terminals until you cut through the part of the connector which is
welded to the post. When you can see a seam between the post and
connector you have drilled through the welded part. See Figs. 191 and
192.

Now pry off the connectors with the screw driver, as shown in Fig.
193. Lay a flat tool such as a chisel or file on the top edge of the
ease to avoid damaging the ease when prying off the connectors.

If any connector is still tight, and you cannot pry it off with a
reasonable effort, drill down a little deeper, and it will come off
easily, provided that the hole which you are drilling is exactly over
the center of the post and as large as the post. There are five things
to remember in drilling the connectors and posts:

[Fig. 192 Connector drilled to correct depth]

(a) Be sure that the hole is exactly over the center of the post.

(b) Do not drill too deep. Make each hole just deep enough so that the
connector will come off easily. Fig. 192 shows a cross section of a
post and connector drilled to the proper depth. Notice that you need
not drill down the whole depth of the connector, because the bottom
part is not burned to the post.

(c) Be sure that the drill makes the right sized hole to permit the
connectors and terminals to be removed easily when drilled half way
through. An electric drill will do the work much faster than a hand
brace.

(d) Protect the edge of the battery box when you pry up the connectors
with a screw driver.

(e) Remove your drill after the hole is well started and see whether
the hole is in the center o
