Battery Check

Charging System Schematic:

Check battery to see if it has the capacity and ability to accept and hold a charge. If battery is OK, then the charging system should be checked to see that it performs its function of keeping the battery charged.

The battery capacity, specific gravity, and cell comparison test (non-maintenance free batteries only), will determine the ability of a battery to accept and hold a charge. If the battery does not meet specification, replace it with a new, fully charged battery before further diagnosis of other areas of the electrical system.

If the battery meets required specifications, it should be fully charged before proceeding with the diagnosis of other electrical system components.
