Battery Testing & Inspection

Follow these instructions in order to avoid an incorrect diagnosis because of connections:

CAUTION: Before servicing any electrical component, the ignition key must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise. If a tool or equipment could easily come in contact with a live exposed electrical terminal, disconnect negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or it's components.
NOTE: Before testing battery, lightly tap eye of hydrometer to ensure that gas bubbles have not lodged themselves in hydrometer. If battery needs replacement, check charging system for proper operation. DO NOT charge a battery with a clear or Yellow indicator. See BATTERY CONDITION INDICATOR  .
