OPERATION AND SERVICE INFORMATION
Page 24
Owner’s Manual and Service Guide
Read all of Manual to become thoroughly familiar with this vehicle. Pay particular attention to all Notes, Cautions and Warnings
when the battery set is fully charged. Always refer to the
instructions of the specific charger used.
Before charging, the following should be observed:
Do not overfill batteries. The charging cycle will expel
electrolyte and result in component damage.
•
The electrolyte level in all cells must be at the rec-
ommended level and cover the plates.
•
The charging must take place in an area that is
well ventilated and capable of removing the hydro-
gen gas that is generated by the charging pro-
cess. A minimum of five air exchanges per hour
is recommended.
•
The charging plug and cord are in good condition
and the ground pin is in place.
AC Voltage
Battery charger output is directly related to the input volt-
age. If multiple vehicles are receiving an incomplete
charge in a normally adequate time period, low AC volt-
age could be the cause and the power company should
be consulted.
Troubleshooting
In general, troubleshooting will be done for two distinct
reasons. First, a battery that performs poorly and is out-
side of the manufacturers specification should be identi-
fied in order to replace it under the terms of the
manufacturer’s warranty. Different manufacturers have
different requirements. Consult the battery manufacturer
or a manufacturer representative for specific require-
ments.
cle does not perform adequately. Performance problems
may result in a vehicle that runs slowly or in a vehicle that
is unable to operate for the time required.
A new battery must
mature before it will develop its max-
imum capacity. Maturing may take up to 100 charge/dis-
charge cycles. After the maturing phase, the older a
battery gets, the lower the capacity. The only way to
determine the capacity of a battery is to perform a load
test using a discharge machine following manufacturer’s
recommendations.
A cost effective way to identify a poorly performing bat-
tery is to use a hydrometer to identify a battery in a set
with a lower than normal specific gravity. Once the partic-
ular cell or cells that are the problem are identified, the
suspect battery can be removed and replaced. At this
point there is nothing that can be done to salvage the
battery; however, the individual battery should be
replaced with a good battery of the same brand, type and
approximate age.

Hydrometer
A hydrometer (P/N 50900-G1) is used to test the state of
charge of a battery cell (Ref Fig. 29 on page 24). This is
performed by measuring the density of the electrolyte,
which is accomplished by measuring the specific gravity
of the electrolyte. The greater the concentration of sulfu-
ric acid, the more dense the electrolyte becomes. The
higher the density, the higher the sate of charge.
