6.View the Meter Display (D) and read the battery condition. Refer to the “Battery Condition Analysis” section below.
7.Release the Toggle Switch (C) and remove the Cable Clamps from the battery.
Testing the Charging System
Note: The engine should be at normal operating temperature during this test.
1.Connect the Cable Clamps (A, B) to the battery as previously described.
2.Outside, or in a well ventilated area, start the vehicle engine and run at fast idle speed. Never start and run the vehicle’s engine in a closed garage.
WARNING! Avoid Carbon Monoxide poisoning.This gas comes from the vehicle exhaust and is colorless and odorless. It can cause serious injury or death if inhaled. Never run the vehicle’s engine inside a garage or any other enclosed space.
3.View the Meter Display (D) and read the charging system condition (far right on the gauge). Refer to the “Battery Condition Analysis” section below.
CAUTION! DO NOT press the Toggle Switch (C) during this test.
Battery Condition Analysis
LOAD TEST / 5 Sec. (Display Reading)
BATTERY CONDITION
OK | Battery capacity is good. May or may not be fully charged. Check the charge state by testing the | |
Specific Gravity (SG) with a Hydrometer. If SG is less than full charge, check for possible charging | ||
(green area) | ||
system trouble. Recharge to full level. | ||
| ||
|
| |
| If the Display Meter needle is steady, the battery capacity is not good. Battery may be defective or | |
WEAK | partly discharged. Check SG. If over 1.225, the battery is defective. If below 1.225, recharge battery | |
and | ||
(yellow area) | ||
be damaged. If charging does not bring SG to full charge level, then battery is either sulfated, or | ||
| ||
| has lost its active material. | |
|
| |
BAD | If the Display Meter needle is falling, the battery is defective or has a bad cell. For a quick check, | |
release the load Toggle Switch and note Display Meter reaction. If voltage recovers to its full | ||
(red area) | potential after only a few seconds, the battery is probably defective. If the voltage recovers slowly, | |
| the battery may only be run down. Check SG, recharge, and | |
|
| |
CHARGING SYSTEM | If the Display Meter needle reads OK, charging system is functional. If it falls on the low red or high | |
(white area) | red areas, charging system may be malfunctioning. | |
