ELECTRICAL SYSTEM

Battery

FIG. 3: The battery (1) is located under the engine hoodin front of the instrument panel. When battery removal,electrolyte inspection, or cable cleaning is required, openthe engine hood.

Keep top of battery clean and make sure cableconnections are clean and tight. Debris on battery cancause discharge of battery and possible fire.

mCAUTION: Batteries produce explosivehydrogen gas when charged. Keep allsparks and open flame away from battery.

When necessary to disconnect batterycables, always disconnect the grounded (-)cable first to prevent short circuits.

Batteries contain sulfuric acid electrolyte(fluid). Wear eye and face protection. Ifelectrolyte comes in contact with skin orclothes, wash immediately. Contactphysician if electrolyte is ingested or getsin eyes.

FIG. 4: If battery replacement is necessary, disconnectnegative (-) cable (1) first and then remove positive (+)cable (2). Loosen and remove battery securing clamp andcarefully remove battery from tractor.

When installing battery, connect cable (2) connected tostarter solenoid to positive (+) battery terminal first. Thenconnect cable (1) grounded to tractor frame to negative (-)battery terminal.

IMPORTANT: Do not reverse battery cable connectionsas severe electrical system damage will result.

NOTE: Make sure replacement battery is of the samesize and equal capacity.

NOTE: Water does not need to be added to battery. Thebattery is a maintenance-free type battery.

Never close or cover vent of battery.

FIG. 5: Battery indicator (1) color shows batterycondition. When checking battery, park machine on alevel surface and check the indicator at top of battery.

If indicator shows clear or light green color, tap batterybody to remove bubble inside indicator.

mWARNING: Never disassemble battery.Batteries contains sulfuric acid electrolyte(fluid). Keep away from sparks or flames,which could cause explosion.

When charging battery from an externalsource, set charging voltage below 16V. Setcharging ampere below 1/10 (one tenth) ofbattery capacity.

When connecting and disconnectingbattery cables, turn off power of batterycharger. If you have any questions aboutthe battery, consult your dealer.

If battery performance is low, remove battery and chargefrom an external supply following battery chargerinstructions. Repeated battery charging can be becauseof a defect in tractor charging system and/or a defectivebattery.

NOTE: When charging battery from an external supply,battery temperature must not be more than54 degrees C (125 degrees F). If batterybecomes too hot, charge rate must be reducedor stopped.

Wiring/Fuse Arrangement

mCAUTION: Keep all wiring connectionsclean and tight. Make sure wiring iscorrectly secured to prevent damage.

mCAUTION: DO NOT alter wiring by addinghome-made extensions or replacements.Doing so can eliminate fuse protectionand/or eliminate safety features of thesystem.

mCAUTION: Tractor is equipped withnegative (-) ground system. Tractor metalparts provide many electrical connections.For this reason, all positive (+) circuits mustbe insulated to prevent grounding or shortcircuits and prevent possible fire.

mCAUTION: DO NOT replace any fuse with afuse of higher amperage rating. DO NOTuse wire (or foil) to by-pass fuse protection.Fire can result.

If fuses blow repeatedly, examine electricalsystem for grounded or shorted circuits.

FIG. 6: Main fuse box (1) - Located on right-hand side atthe rear of the engine.

Slow blow fuses (2) are located above and to the right ofbattery. Slow blow fuses are inline fuses that protect acircuit by melting when sustained heavy electrical load orshort circuit is found. Slow blow fuses give a delayedaction to prevent current break when short surges arefound.

IMPORTANT: Fuses are of specific amperage for thecircuit. Do not replace fuses with unauthorizedparts.

NOTE: Failure of alternator circuit slow blow fuse isnormally caused from not correct polarity (suchas reversed cables when using a boosterbattery). A failed fuse will not let battery becharged during normal operation.

FIG. 7: Main fuse box components:

Slow blow fuses:

(6) A 40A slow blow fuse is green and protects the maincircuit.

(7) A 40A slow blow fuse is green and protects thealternator circuit.

Neutral Starting Switches

This tractor is equipped with a neutral-start systemconsisting of neutral switches and a relay. To start thetractor, ALL the following is required:

• Range shift lever must be in neutral position.

• PTO control lever must be OFF.

mWARNING: DO NOT bypass or modify theneutral switch. If the neutral start systemdoes not operate properly, consult yourDealer immediately.
