2. Insert BLACK test lead into

COM test lead jack.

3. Insert RED test lead into "10A"

(or "mA") test lead jack.

4. Disconnect positive (+) battery

cable.

5. Connect RED test lead to posi-

tive (+) battery terminal.

6. Connect BLACK test lead to

positive (+) battery cable.

NOTE: Do not start vehicle dur-
ing this test, because multimeter
damage may result.

7. Turn multimeter rotary switch

to 10A DC (or 200 mA) posi-
tion.

8. View reading on display.

• Typical current draw is 100mA.

(1mA = 0.001A)

• Refer to vehicle service manual

for manufacturers specific En-
gine Off Battery Current 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 manu-
facturers specifications.

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 lo-
cated.

- Non-Fused circuits such as

headlights, relays, and sole-
noids should also be checked
as possible current drains on
battery.

- When source of excessive cur-

rent drain is found, service as
necessary.

Engine Off Battery
Current Draw

This test measures the amount of
current being drawn from the battery
when the ignition key and engine are
both off. This test helps to identify
possible sources of excessive bat-
tery current drain, which could even-
tually lead to a “dead” battery.

1. Turn Ignition Key and all ac-

cessories OFF.

Make sure trunk, hood, and
dome lights are all OFF.
