Battery Inspection - Solar 1874 Mode D'emploi

SAFETY
• Carefully read all operating instructions before using the tester.
• Wear eye protection when working around batteries.
• Be sure each test is completed before removing load clamps to prevent arcing and potential explosion from battery
gasses. Never remove load clamps while testing. Keep sparks, flames, or cigarettes away from batteries.
• Keep hair, hands, and clothing as well as tester leads and cords away from moving blades and belts.
• Provide adequate ventilation to remove vehicle exhaust.
• In extremely cold temperatures, check for frozen electrolytic fluid before applying load. Do not attempt to load test or
charge a battery under 20˚F. Allow the battery to warm before testing or charging.
• Warning! Never attach the unit to a battery that is connected to any other tester or charging unit. Damage may result.
CAUSES OF BATTERY FAILURE
Incorrect Application: Wrong size battery may have inadequate cold cranking rating for original vehicle specifications.
Incorrect Installation: Loose battery hold-downs cause excessive vibration, which can result in damage to the plates.
Improper Maintenance: Low electrolytic fluid and corrosion on battery connections can greatly reduce battery life and
affect battery performance.
Age of Battery: If the date code on the battery indicates it is old, the failure may be due to natural causes.
Overcharging: Overcharging caused by a high voltage regulator setting or incorrect battery charging can cause
excessive gassing, heat and water loss.
Undercharging: Undercharging caused by a faulty charging system or low voltage regulation can cause lead sulfate to
gradually build up and crystallize on the plates, greatly reducing the battery's capacity and ability to be recharged.

BATTERY INSPECTION

Valid automotive electrical system testing depends on all the components being in good operating condition.
In addition, the battery MUST have sufficient charge for testing. Carefully perform the following before attempting
any electrical diagnosis.
• Inspect Battery for terminal corrosion, loose or broken posts, cracks in the case, loose holddowns, low electrolyte
level, moisture, and dirt around the terminal.
Note: A known defective battery must be replaced before proceeding with any test of the charging / starting system.
• Inspect Belts for cracks, glazed surface and fraying. Tighten loose belts. Inspect belt tensioner for proper alignment.
• Inspect Starting System. Check starter, solenoid, and alternator for loose connections, loose mounts and frayed or
cracked wires.
