54A-BATTERY TEST

BATTERY TEST

BATTERY TESTING PROCEDURE

STEP 1. Check the battery cables.

(1) Remove the negative cable, then the positive cable.

(2) Check for dirty or corroded connections.

Are the battery cables dirty or have corroded connections?

Clean the battery cables. Then go to Step 2

Go to Step 2

STEP 2. Check the battery posts.

Check for loose battery post.

Are the battery posts loose?

Replace the battery.

Go to Step 3

STEP 3. Check the battery case and cover.

(1) Remove the hold-downs and shields.

(2) Check for broken/cracked case or cover.

Is the battery case or cover faulty?

Replace the battery.

Go to Step 4

STEP 4. Check the open circuit voltage.

(1) Turn headlights on for 15 seconds.

(2) Turn headlights off for two minutes to allow battery positive voltage to stabilize.

(3) Disconnect the battery cables.

(4) Read open circuit voltage.

Is open circuit voltage 12.4 volts or more?

Go to Step 6

Go to Step 5

STEP 5. Battery charging

Charge the battery. (See CHARGE RATE CHART

)

Is open circuit voltage 12.4 volts or more?

Go to Step 6

Replace the battery.

STEP 6. Check the load test.

(1) Connect a load tester to the battery.

(2) Load the battery at the recommended discharge rate (See LOAD TEST RATE CHART) for 15 seconds.

(3) Read voltage after 15 seconds, then remove load.

(4) Compare the measured value with the minimum voltage. (See LOAD TEST CHART.)

Is the voltage higher than minimum voltage?

The battery is normal.

Replace the battery.
