ENGINE ELECTRICAL 6D1-3
Diagnosis 1. Visual Inspection Inspect the battery for obvious physical damage, such as a
2. Hydrometer Check
3. Fluid Level Check The fluid level should be between the upper level line (2) and a. CORRECT FLUID LEVEL - Charge the battery. b. BELOW LOWER LEVEL - Replace battery.
4. Voltage Check 1. Put voltmeter test leads to battery terminals. a. VOLTAGE IS 12.4V OR ABOVE - Go to Step 5. b. VOLTAGE IS UNDER 12.4V - Go to procedure (2) below. 2. Determine fast charge amperage from specification. (See Main Data and Specifications in this section). Fast charge battery for 30 minutes at amperage rate no higher than specified value. Take voltage and amperage readings after charge. a. VOLTAGE IS ABOVE 16V AT BELOW 1/3 OF AMPERAGE RATE - Replace battery. b. VOLTAGE IS ABOVE 16V AT ABOVE 1/3 OF AMPERAGE RATE - Drop charging voltage to 15V and charge for 10 - 15 hours. Then go to Step 5. c. VOLTAGE IS BETWEEN 12V AND 16V - Continue charging at the same rate for an additional 3-1/2 hours. Then go to Step 5. d. VOLTAGE BELOW 12V - Replace Battery.
