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
and replaced with a good battery of the same brand, type
and approximate age.
BATTERY CHARGER MAINTENANCE
Plug charger into vehicle receptacle and wait for relay to
turn on. Check to see if charger turns off by moving plug
back and forth in receptacle. If charger does turn off,
check plug for a broken red wire in DC cord.
PROLONGED STORAGE
Battery charger, controller and other
electronic devices need to be discon-
nected since they will contribute to the premature discharge of
batteries.
During periods of storage, the batteries will need atten-
tion to keep them maintained and prevent discharge.
In high temperatures the chemical reaction is faster,
while low temperatures cause the chemical reaction to
slow down. A vehicle that is stored at 90° F (32° C) will
lose .002 of specific gravity each day. If a fully charged
battery has a specific gravity of 1.275, and the battery is
allowed to sit unused, it will become partially discharged.
When it reaches 1.240, which it will do in less than
twenty days, it should be recharged. If a battery is left in
a discharged state, sulfating takes place on and within
the plates. This condition is not reversible and will cause
permanent damage to the battery. In order to prevent
damage, the battery should be recharged. A hydrometer
can be used to determine the specific gravity and there-
fore the state of charge of a battery.
In winter conditions, the battery must be fully charged to
prevent the possibility of freezing (Ref. Fig. 33 on page
25). A fully charged battery will not freeze in tempera-
tures above -75° F (-60° C). Although the chemical reac-
tion is slowed in cold temperatures, the battery must be
stored fully charged, and disconnected from any circuit
that could discharge the battery. For portable chargers,
disconnect the charging plug from the vehicle receptacle.
For on-board chargers, disconnect the charging harness
from the batteries. The batteries must be cleaned and all
deposits neutralized and removed from the battery case
to prevent self discharge. The batteries should be tested
or recharged at thirty day minimum intervals.
