Premier L4-150 2.5L (1988)
FIGURE 2
BUILT-IN TEST INDICATOR (STATE OF CHARGE)
One of three conditions can be observed from the test indicator. They are as follows:
1.
Green dot (Figure 2 - State of Charge - Chart 1). Any green appearance is interpreted as above 75% state of charge. This indicates that the battery
is adequately charged for testing. On rare occasions following prolonged cranking, the green dot may still be visible. Should this occur, charge the
battery as described in "Battery Charging Procedures".
2.
A dark or black dot (Figure 2 - State of Charge - Chart 1). A dark or black dot indication is a result of the battery being partially discharged below
a 75% state of charge level. The battery should be checked as described in "Battery Charging Procedures" until Green Dot is visible prior to
performing any other tests.
3.
Bright or Yellow Dot.
WARNING:
ON RARE OCCASIONS, TEST INDICATOR MAY TURN LIGHT YELLOW OR BRIGHT IN COLOR. THIS INDICATES
LOW ELECTROLYTE LEVEL. IN THIS CASE, THE VEHICLE CHARGING SYSTEM SHOULD BE THOROUGHLY
CHECKED FOR BATTERY OVERCHARGED CONDITION AS COVERED IN APPLICABLE SECTION OF THE SERVICE
MANUAL. ALTHOUGH BATTERY MAY APPEAR SERVICEABLE, REPLACE THE BATTERY. DO NOT ATTEMPT TO
CHARGE, TEST, OR JUMP START THE VEHICLE.
IGNITION OFF BATTERY DRAIN
Vehicle batteries have a normal small continuous drain with ignition switch turned off. A 20-35 milliampere drain is common. This is due to digital
clocks and solid state devices, that operate while the ignition is off. In addition, there may be other conditions in the electrical system that causes
excessive Electrical Drain on a battery. Shorted or pinched wires, misadjusted switches, faulty components and other conditions may cause battery to
discharge at a very fast rate even when all accessories are turned off. To check for electrical drain refer to "Ignition Off Drain Test".
FIGURE 3
IGNITION OFF DRAIN TESTS
To test for excessive ignition off drain, verify that all electrical accessories are OFF. Turn off all lights, remove ignition key, and close all doors and
decklid. If the vehicle is equipped with electronic accessories (illuminated entry, automatic load leveler, body computer, or highline radio), allow the
systems to automatically shut off (time out), up to 3 minutes.
1.
Raise the hood and disconnect both battery cables, negative first.
2.
Reconnect the negative cable and connect a typical 12-volt test light between the positive cable clamp and the positive battery post (Figure 3).
