Understanding Advanced Diagnostics.
Advanced Diagnostics displays charging errors by flashing Error LED and Standby LED flashing back and forth. The number of flashes between
each pulse denotes the potential Error Condition (except reverse polarity and low-voltage battery).
Error Reason/Solution

Double Flash

Triple Flash
Battery voltage is too high. Check the battery voltage and charge mode.
Error LED Solid Red Reverse battery connections.
Standby Solid Orange Battery voltage is too low to detect the battery. Jump start the battery to raise the battery voltage.
Explanation
The Charge LED will slowly pulse "on" and "off" when the battery is less than 75% fully charged.
The Charge LED will slowly pulse "on" and "off" when the battery is less than 90% charged.
When the battery is 100% charged, the Charge LED will be solid green.
During maintenance charging, the 100% Charge LED will pulse "on" and "off" slowly. When the
battery is topped off and fully charged again, the 100% Charge LED will turn solid green. The
charger can be left connected to the battery indefinitely.
