should be removed and both the box and battery cleaned by the following procedure:
a. Remove the box drain cap from the underside of the fuselage and drain off any
electrolyte that may have overflowed into the box.

solution of baking soda and water mixed to a consistency of thin cream. The application of
this mixture should be applied until all bubbling action has ceased.

NOTE
If a solderless terminal on an aluminum cable is loose, corroded
or otherwise unsatisfactory, it is recommended that the com-
plete cable assembly be replaced instead of replacing or repair-
ing the solderless terminal.
Should replacement of the complete assembly not be prac-
tical, it is permissible to replace the aluminum cable assembly
with a copper cable assembly which is two sizes smaller (ex.: An
AL-I aluminum cable assembly is replaced with an AN-3 cop-
per cable assembly).
The new cable should be installed in accordance with AC-43-
13-2A.
