Section 6: Maintenance

Common circuit failures can be from “shorts”, corroded or dirty terminals, loose connections, defective wire insulation or broken wires. Switches, solenoids and ignition components can also not function, causing a short or open circuit.

Before attempting any fault diagnosis of the electrical system, use a test light or voltmeter to check the battery voltage. If the battery voltage is satisfactory, check the cleanliness and tightness of the terminals and ground connections. A general understanding of electrical servicing and use of basic test equipment is necessary for troubleshooting and repair.

Major overhaul or repair of the starting motor or alternator should be performed by trained technicians only.


The battery is located in the engine compartment. It may be either a maintenance-free sealed battery or a maintenance-free battery with removable vent caps. Inspect your battery and know which battery your have. Water can not be added to sealed batteries as the vent caps are not removable.


Do not overfill battery with water. Electrolytes may overflow and damage paint, wiring or structure. Use soap and water to clean the battery. Be careful not to get soap and water into the battery. Use baking soda mixed in water to clean corrosion off the terminals.


Acid can cause serious injury to skin and eyes. Avoid skin contact with battery acid and always wear eye protection when checking the battery. Flush area with clean water and call a physician immediately. Acid will also damage clothing.


Incorrect battery cable connections can damage vehicle’s electrical system and cause battery cables to spark. Sparks around a battery can result in a battery gas explosion and personal injury.

  • Always disconnect negative (black) battery cable before disconnecting positive (red) cable.

  • Always reconnect positive (red) battery cable to the positive (+) post before reconnecting negative (black) cable to the negative (-) post.


Sparks can cause a battery gas explosion which will result in personal injury. Keep battery terminals from touching any metal parts when removing or installing the battery. Do not allow metal tools to short between battery terminals and metal vehicle parts.


Do not allow an open flame near the battery when charging. Hydrogen gas forms inside the battery. This gas is both toxic and flammable and may cause an explosion if exposed to a flame.

Check water level once a year. The water level in each cell should be up to the level indicator. If not, add water. Distilled water should be used to fill each cell in the battery. However, tap water may be used if tap water is not hard or does not have high mineral or alkali content. Do not overfill. Have the charging system checked by your local Land Pride dealer if the battery requires water every few months.

Land Pride recommends a maintenance-free battery size BCI group U1/U1R. The battery should also have a minimum of 300 cold cranking AMP’s and 375 cranking AMP’s at 32oF. Always follow the manufacturer’s maintenance, safety, storing and charging specifications.

Jump Starting the Battery

Refer to Figure 6-3

The battery will discharge if the lights or any other electrical equipment is left on after the engine has stopped running. Also, the battery will discharge if the lights or power plug outlet is used over a prolong period while the engine is idling.

The engine can be jump-started with a booster battery. Follow procedures listed below when jump-starting.

Prepare Vehicle to Jump-Start

  • 1.

    Use only a 12-volt battery to jump-start the ATR. Higher voltages can damage the starter motor and other electrical components. Do not use a 24 volt battery or two 12-volt batteries connected in series.

  • 2.

    Do not disconnect the vehicle’s battery that needs a jump-start. Disconnecting the battery can damage the vehicle’s electrical system.

  • 3.

    Park the live vehicle close to the vehicle needing a boost without touching the two vehicles together. Set parking brake on both vehicles.

  • 4.

    Turn off all ignition switches, electric switches, light switches and set parking brakes on both vehicles.
