MAINTENANCE
Read all of this manual to become thoroughly familiar with this vehicle. Pay particular attention to all Notices, Cautions, Warnings, and Dangers.

Aerosol containers of battery terminal protectant must be used with extreme care. Insulate the metal con-
tainer to prevent the can from contacting the battery terminals.
Battery Replacement
Before any electrical service is performed on TruCourse technology model vehicles, the Run-Tow/Maintenance
switch must be placed in the ‘Tow/Maintenance’ position.
If a power wire (battery, motor or controller) is disconnected for any reason, the Run-Tow/Maintenance switch must
be left in the ‘Tow/Maintenance’ position for at least 30 seconds after the circuit is restored.
Remove battery hold downs and cables. Lift out batteries with a commercially available lifting device.
If the batteries have been cleaned and any acid in the battery rack area neutralized as recommended, no corrosion
to the battery racks or surrounding area should be present. Any corrosion found should be immediately removed with
a putty knife and a wire brush. The area should be washed with a solution of sodium bicarbonate (baking soda) and
water and thoroughly dried before priming and painting with a corrosion resistant paint.
The batteries should be placed into the battery racks and the battery hold downs tightened to 45 - 55 in. lbs. (5 - 6
Nm) torque, to prevent movement but not tight enough to cause distortion of the battery cases.
Inspect all wires and terminals. Clean any corrosion from the battery terminals or the wire terminals with a solution of
sodium bicarbonate (baking soda) and brush clean if required.
To prevent battery explosion that could result in severe personal injury or death, extreme care
must be used with aerosol containers of battery terminal protectant. Insulate the metal container
to prevent the metal can from contacting battery terminals which could result in an explosion.
Use care to connect the battery wires as shown.
Tighten the battery post hardware to 90 - 100 in. lbs. (6 -8
Nm) torque
.
Do not over-torque the terminal stud nut, this
will cause a “mushroom” effect on the battery post which
will prevent the terminal nut from being properly tight-
ened.Protect the battery terminals and battery wire termi-
nals with a commercially available coating.
Protect the battery terminals and battery wire terminals
with a commercially available coating.
Prolonged Storage
Battery charger, controller and other electronic devices
need to be disconnected since they will contribute to the
premature discharge of batteries.
The ’RUN-TOW/MAINTENANCE/STORAGE’ switch, located under the passenger seat is set to ‘TOW/MAINTENANCE/STOR-
AGE’ position for long term storage of the vehicle to avoid draining of the batteries.
During periods of storage, the batteries will need attention to keep them maintained and prevent discharge. In high tem-
peratures 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
