1J-2 Charging System:
• Green Dot:
Battery is sufficiently charged for testing.
• Dark:
Battery must be charged before testing.
If there is a cranking complaint, battery should be tested as described in “Battery Inspection: ”.
Charging and electrical systems should also be checked at this time.
• Clear or Light Yellow:
This means that fluid level is below the bottom of hydrometer. Its possible cause is excessive or prolonged
charging, a broken case, excessive tipping or normal battery deterioration.
When the battery is found in such condition, it is possible that high charging voltage is caused by the faulty charging
system and therefore, charging and electrical systems need to be checked. If there is a trouble in cranking and its
cause lies in the battery, it should be replaced.
