Engine Off Battery
Current Draw
• Refer to vehicle service manual
for manufacturers specific 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 battery current drain, which could eventually lead to a “dead” battery.
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 specifications.
1. Turn Ignition Key and all accessories OFF.
Excessive Current Draw:
Make sure trunk, hood, and
dome lights are all OFF.
- Display reading in Step 8 is
well outside manufacturers
specifications.
(See Fig. 18)
- 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.

2. Insert BLACK test lead into
COM test lead jack.
- When source of excessive current drain is found, service as
necessary.
3. Insert RED test lead into "10A"
(or "mA") test lead jack.
4. Disconnect positive (+) battery
cable.
5. Connect RED test lead to positive (+) battery terminal.
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 10A DC (or 200 mA) position.
8. View reading on display.
• Typical current draw is 100mA.
(1mA = 0.001A)
