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

IC REGULATOR CHECKING PROCEDURE

Models          All Models
Bulletin No.    058/83
Category        5
Date            11/9/83

DESCRIPTION

   Checking procedure for the built-in IC regulator has been
established to pin point the alternator problem. Basically, the
alternator should be replaced as a unit through the exchange program.
However, in case of a shortage of refurbished alternators, you may
replace the IC regulator to minimize inconvenience of customers (see
Fig. 1).

PARTS INFORMATION

         Regulator       N221 24 520

CHECKING PROCEDURE

   1. Make sure the battery is fully charged.
   2. Turn ignition key on to "Ig" position. If the alternator warning
      light is "off", the problem is likely to be caused by regulator.
      Leave the key in "Ig" position and take the following step to
      assure the cause.
   3. Insert volt meter between "F" terminal and nearest ground point
      (Fig. 2).
   4. Do not ground to the body of the alternator while positive probe
      of voltmeter is inserted through the hole for "F" terminal.
