Battery and Cables
Before working on any part of the electri-
cal system, disconnect the battery ground
cable at the battery negative (-) terminal. See
lllust.17. Do not reconnect this cable until all
work has been completed. This will prevent
shorting and damage to any of the electrical
units. Examine the electrical cables occasion-
ally to be sure they are not being frayed by
contact with adjacent parts.
When replacing a battery, make certain the
ground cable is connected to the negative (-)
terminal on the battery. Be sure the rubber
boot is properly positioned over the positive
(+) terminal on the battery. Note: Both cables
must be assembled with the nuts to the inside
of the terminals to prevent shorting against
the pedestal.
Cleaning and Servicing the Battery
Occasionally remove the battery cables and
brighten the terminal contact surfaces with
wire wool, and reassemble them. Apply a
light coat of vaseline or chassis lubricant. Be
sure the terminals are clamped tightly and
that the battery is fastened securely in the bat-
tery box. Replace unserviceable cable. Keep
the vent holes in the battery filler caps open.

Keeping the battery fully charged not only
adds to its life but makes it available for instant
use when needed.
Liquid Level
Check the battery at least once a month for
water level.
The electrolyte (acid and water) in each
cell should be at ring level at all times to pre-
vent battery failure. When the electrolyte is
below this level, add pure, distilled water.
Acid or electrolyte should never be added
except by a skilled battery man. Under no
circumstances add any special battery "dopes, "
solutions or powders.
Caution! Electric storage batteries give off
highly inflammable hydrogen gas when charg-
ing and continue to do so for some time after
receiving a steady charge.
Caution! Do not under any circumstances
allow an electric spark or an open flame near
the battery. Do not lay tools across battery
terminals as this may result in a spark or
short circuit which may cause an explosion.
Be careful to avoid spilling any electrolyte
on hands or clothing.
