Good Battery
If a battery has tested good and continues to discharge in service, the following
are possible causes to the problem:
• | Vehicle accessories left On. |
• | Conditions in charging system such as slipping belt, high wiring resistance,
faulty generator/charging system. |
• | Blown fusible link between starter and generator. |
• | Vehicle electrical load exceeding capacity of generator. |
• | Extended low speed driving with many electrical accessories turned On. |
• | Conditions in vehicle electrical system such as shorted wired or high
parasitic current loads. |
| Notice: Do not check for battery terminal tightness by rotating the cable while attached
to the battery. This could cause the battery lug face to be damaged and result in
a poor electrical connection.
|
• | Loose cable connection, loose hold downs or
improper charging of a previously run down battery. |
• | Corroded or loose cable connections or other cranking system condition. |
• | Long periods of vehicle storage without disconnecting the battery. Parasitic
loads can discharge a battery in a 4 to 6 weeks. |
| Important: A dead battery is usually a symptom of another problem. Fix the problem, don't
just charge battery.
