AGS-10
UnclassifiedElectrical
What This Code Means
Red LED stays on for more than 24 hours; Red and green LEDs stay on for more than 24 hours; Green LED stays on when the battery is known to be below (normal charge level); Neither of the LEDs turn on when the AC power is applied; Green LED is off and there is no output voltage
Possible Causes
- •One or more inoperative or damaged cells
- •Battery charger has reduced its output voltage below the normal level due to a DC overload or a DC short
- •Onboard DC systems are drawing more current than the battery charger can replace
- •Onboard DC systems are drawing between 1.5 and 5 amps
- •Extremely low AC voltage at the battery charger
- •Open DC output fuse (AGS-10)
- •Faulty or contaminated terminal connections
- •No AC power available at the battery charger
- •Component failure
- •No power to the battery charger
- •Check the upstream circuit breakers and fuses
- •Check fuse FS (1A-T) inside the battery charger
Suggested Actions
- 1Load test the battery and replace, if necessary
- 2Remove the source of the overload or short. Disconnect the battery charger’s black (NEGATIVE) ring terminal from the battery. Reapply AC power and the green LED only should now light.
- 3Turn off all DC equipment while charging.
- 4Load test the battery and replace, if necessary.
- 5Apply a higher AC voltage source or reduce the length of the extension cord.
- 6Replace AGS-10 fuse.
- 7Clean and tighten or repair all terminal connections.
- 8Connect AC power or reset the AC breaker on the main panel.
- 9Replace battery charger.
- 10Check the power supply to the charger.
- 11Check the upstream circuit breakers and fuses.
- 12Check fuse FS (1A-T) inside the battery charger.
