3. BASIC INSPECTION

1) Battery Terminal

Make sure the terminal connections are

securely tightened. If the terminals are

corroded, clean them or replace the battery.

-

* Cleaning

Remove the corrosion or dirt with a wire brush

or sand paper, and then wash out with

lukewarm soapy water.

2) Measuring the Voltage Drop

Measuring at battery terminal

▶

Measure the voltage between battery

terminal (+. -) and wiring clamp.

-

Specified value

below 0.3V

If the terminals are corroded, clean and

retightening them. If the specified tightening

torque cannot be kept, replace the clamp.

Terminal (+)

Terminal (-)

Terminal (+): 4 ~ 5 Nm
Terminal (-): 6 ± 1Nm

14-6

Measuring at (-) wiring

▶

Measure the voltage between battery wiring

and body ground.

-

Specified value

below 0.3V

If the voltage is out of the specified value,

check the wiring mounting bolt for corrosion

and looseness. If there is a poor contact due

to corrosion or paint, wipe out the contact area

and retighten it.

Wiring mounting bolt to body

ground (-): 17 Nm

Measuring the battery voltage

▶

Stop the engine and wait for 20 minutes.

Measure the voltage between terminal (+)

and terminal (-) with the ignition switch OFF

and all electric devices OFF.

-

Specified value

over 12V

14-7

0000-00

Measuring the voltage drop between lines

▶

Measure the voltage drop between alternator B+ and battery B+.

-

Specified value

below 0.3V

If the value is out of the specified value, check the terminal and clamp for looseness.

Checking the charge warning lamp

▶

Turn off all electric devices and put the ignition switch “ON” (Pre-warning).

Check if the charge warning lamp goes out.

If the charge warning lamp does not go off, inspect the electric circuit.

Start the engine and check if the charge warning lamp keeps off.
