See your authorized dealer.

Battery Uses Too Much Water

Cracked battery case

Replace battery.

High ambient temperature

Refill with water.

Shorted cell

Check if one or more cells take more water than the others. Check specific gravity. (See Checking Electrolyte Specific Gravity in Maintenance.)

Cracked Battery Case

No battery hold-down clamp

Replace battery and install hold-down clamp.

Loose battery hold-down clamp

Replace battery and install hold-down clamp.

Symptom Problem Solution

Low Battery Output

Low water level

Add water.

Dirty or wet battery top, causing discharge

Clean and wipe battery top dry.

Corroded or loose battery cables

Clean and tighten battery cables.

Broken battery post

Wiggle battery post by hand. If post wiggles or turns, replace battery.

Low battery voltage

Measure "stabilized" battery voltage. Stabilize voltage by actuating horn for 30 seconds. If stabilized voltage is below 12 volts, charge battery.

Battery cell

Measure specific gravity of each cell. If more than 50 points between cells, replace battery. (See Checking Electrolyte Specific Gravity in Maintenance.)

Symptom Problem Solution

Starter Does Not Work or Turns Slowly

Hydraulic load

Turn steering wheel back and forth to relieve hydraulic pressure while engine is turning.

Excessive electrical load

Remove excessive load or install larger alternator. See your authorized dealer.

Loose or corroded connections

Clean and tighten.

Low battery power

Check specific gravity of electrolyte. (See Checking Electrolyte Specific Gravity in Maintenance.)

Wrong viscosity engine oil

Inspect engine oil. (See Fuels and Lubricants chapter.) Change oil. (See Change Engine Oil and Replace Filter in Maintenance-Every 250 Hours.)

Blown starter and park start fuse

Replace fuse F2.

Corroded, loose, or broken battery post

Wiggle battery post by hand. If post wiggles or turns, replace battery.

Low battery voltage

See Low Battery Output.

Starter Solenoid Chatters

Poor or corroded connections at battery, battery ground strap, or starter

Inspect, clean, and tighten if necessary.

Low battery voltage

See Low Battery Output.

Engine Alternator Voltage Indicator is ON

Loose or glazed alternator belt

Check belt. Replace if glazed, tighten if loose. (See Inspect Serpentine Belt in Maintenance-As Required.)

Engine rpm low

Raise engine rpm above 1000 rpm. If indicator remains on, see your authorized dealer.
