GENERAL INFORMATION
Parasitic Load Explanation & Test Procedures
* PLEASE READ THIS FIRST *
This article is provided for general information only. Not
all procedures apply to all makes and models.
GENERAL INFORMATION
The term Parasitic Load refers to electrical devices that
continue to use or draw current after the ignition switch is turned to
OFF position. This small amount of continuous battery draw is
expressed in milliamps (mA). On Ford Motor Co. and General Motors
vehicles produced after 1980, a typical Parasitic Load should be no
more than 50 milliamps (0.050 amps).
Vehicles produced since 1980 have memory devices that draw
current with ignition off for as long as 20 minutes before shutting
down the Parasitic Drain. When Parasitic Load exceeds normal
specifications, the vehicle may exhibit dead battery and no-start
condition.
Follow test procedure for checking Parasitic Loads to
completion. A brief overview of a suggested test procedure is included
along with some typical Parasitic Load specifications. Refer to the
GENERAL MOTORS PARASITIC LOAD TABLE chart.
TESTING FOR PARASITIC LOAD
INTRODUCTION
CAUTION: Always turn ignition off when connecting or disconnecting
battery cables, battery chargers or jumper cables. DO NOT
turn test switch to OFF position (which causes current to run
through ammeter or vehicle electrical system).
NOTE: Memory functions of various accessories must be reset after
the battery is reconnected.
The battery circuit must be opened to connect test switch
(shunt) and ammeter into the circuit. When a battery cable is removed,\
timer circuits within the vehicle computer are interrupted and
immediately begin to discharge. If in doubt about the condition of the
ammeter fuse, test it with an ohmmeter prior to beginning test. An
open fuse will show the same reading (00.00) as no parasitic drain.
Begin test sequence with the meter installed and on the 10-amp scale.
Select lower scale to read parasitic draw.
TEST PROCEDURE USING TEST SWITCH
1) Turn ignition off. Remove negative battery terminal cable.
Install Disconnect Tool (J-38758) test switch male end to negative
battery cable. Turn test switch knob to OFF position (current through
meter). Install negative battery cable to the female end of test
switch.
2) Turn test switch knob to ON position (current through
switch). Road test vehicle with vehicle accessories on (radio, air
conditioner, etc.). After road test, turn ignition switch to LOCKED
position and remove key. Connect ammeter terminals to test switch

DISTRIBUTOR
Removal (Dakota 2.5L)
1) Disconnect negative battery cable. Remove air inlet duct
between throttle body and air cleaner assembly. Remove distributor
cap. Disconnect electrical connector for distributor.
2) Remove spark plug from cylinder No. 1 at timing chain end
of engine. Rotate crankshaft clockwise (viewed from front of engine)
until cylinder No. 1 is at Top Dead Center (TDC) on compression stroke\
and timing mark on vibration damper aligns with "0" degree timing mark
on timing chain cover. DO NOT rotate crankshaft counterclockwise to
align timing marks.
3) Remove distributor hold-down bolt and hold-down clamp.
Remove distributor with gasket from cylinder block.

block. Install distributor so distributor shaft engages with slot in
oil pump drive gear. It may be necessary to slightly rotate
distributor during installation.
6) When distributor is fully seated, the distributor rotor
should be at 3 o'clock position and center of hold-down bolt area on
distributor housing should align with distributor hold-down bolt area
on cylinder block.
7) Install hold-down clamp and distributor hold-down bolt.
Tighten distributor hold-down bolt to specification. See TORQUE
SPECIFICATIONS.
8) If installing a factory replacement distributor, remove
plastic alignment pin from distributor housing. If installing original
or used distributor, remove drift from distributor housing and
reinstall camshaft position sensor. On all applications, install
distributor cap and remaining components. Base ignition timing is
nonadjustable, as ignition timing and timing advance are controlled by
the Powertrain Control Module (PCM).
Removal (Dakota 3.9L, 5.2L & 5.9L, Durango, Ram Pickup 3.9L,
5.2L & 5.9L, Ram Van & Ram Wagon)
1) Disconnect negative battery cable. On Ram Van and Ram
Wagon, remove engine cover. On all models, remove air cleaner
assembly. Remove distributor cap. Disconnect electrical connector for
distributor.
2) Rotate crankshaft clockwise (viewed from front of engine)\
until cylinder No. 1 is at Top Dead Center (TDC) on compression stroke\
and timing mark on vibration damper aligns with TDC timing mark on
timing chain cover. Cylinder No. 1 is the front cylinder on driver's
side of engine.
3) Ensure distributor rotor aligns with cylinder No. 1
alignment mark on camshaft position sensor. See Fig. 23. If
distributor rotor is not properly aligned, rotate crankshaft clockwise
one full revolution. Ensure distributor rotor aligns with terminal for
cylinder No. 1 on distributor cap.
4) Scribe a mark on distributor and adjacent component to
indicate rotor and distributor housing position for installation
reference. Remove distributor hold-down bolt and hold-down clamp.
Remove distributor with "O" ring from cylinder block.
