CURRENT DRAW FROM THE BATTERY
Model: All Models
Bulletin No.: 017/88
Date: 7/27/88
Category: 5
DESCRIPTION
In order to maintain the memory of the electrical equipment such as
radio, clock, and several other control units, a small amount of
current is drawn from the battery even though the vehicle is not in
use. Although the actual current may vary according to the electrical
equipment in each vehicle, the following specification can be used to
determine if the current draw of the vehicle in question is normal or
not.
CURRENT DRAW AMPERAGE
All Vehicles: 15 to 25 mA (Ignition key is removed or in the lock
position).
NOTE:
If the ignition key is in the ACC position, up to 250 mA is drawn from
the battery. This current draw is large enough to discharge the
battery in a few days.
TEST PROCEDURES
1. Turn the ignition switch off and remove the key from the cylinder.
2. Turn off all electrical loads. Make sure all doors and the trunk
lid are completely closed.
3. Open the hood and disconnect the negative battery terminal.
NOTE:
If the vehicle is equipped with theft-deterrent system, disconnect the
coupler from the hood switch so that the warning light of the theft-
deterrent system is not operable.
4. Set the circuit tester to the "DC mA" range, to at least 100 mA
range and check the current as follows:
Positive lead from tester to Negative Battery Cable
Negative lead from tester to Negative Battery Post.
CAUTION:
Do not open the door while checking the current, as the tester will be
