2. Insert BLACK test lead into COM test

lead jack.

3. Insert RED test lead into "15A" test lead

jack.

4. Disconnect positive (+) battery cable.

5. Connect RED test lead to positive (+)

battery terminal.

This test measures the amount of current

being drawn from the battery when the igni-

tion key and engine are both off. This test

helps to identify possible sources of exces-

sive battery current drain, which could even-

tually lead to a “dead” battery.

1. Turn Ignition Key and all accessories

OFF.

Make sure trunk, hood, and dome lights

are all OFF.

(See Fig. 19)

6. Connect BLACK test lead to positive (+)

battery cable.

NOTE: Do not start vehicle during this test,

because multimeter damage may result.

7. Turn multimeter rotary switch to 15A

DC position.

8. View reading on display.

• Typical current draw is 100mA. (1mA =

0.001A)

• Refer to vehicle service manual for manu-

facturers specific Engine Off Battery Cur-

rent Draw.

NOTE: Radio station presets and clocks

are accounted for in the 100mA typical

current draw.

9. Test Results.

Normal Current Draw:

Display reading in

Step 8 is within manufacturers specifica-

tions.

Excessive Current Draw:

- Display reading in Step 8 is well outside

manufacturers specifications.

- Remove Fuses from fuse box one at a

time until source of excessive current

draw is located.

- Non-Fused circuits such as headlights,

relays, and solenoids should also be

checked as possible current drains on

battery.

- When source of excessive current drain

is found, service as necessary.
