Schumacher 520A-PE Troubleshooting Guide
The battery charger is designed to work automatically. However, if a problem does occur, check the following:
PROBLEM POSSIBLE CAUSE SOLUTION
No meter reading Charger is not plugged in. Plug the charger in.
Connections are reversed. With charger unplugged, reverse clips and reconnect (rock back and forth to bite in).
Poor electrical connection Clean clips and battery poles and reconnect (roll back and forth to bite in).
AC outlet is dead. Plug in a known working lamp to check for voltage.
Battery is defective (will not accept charge). Have battery checked.
Charger will not turn on (when properly connected to power). battery recently used in vehicle and is fully charged. Battery does not need charging.
(If battery is in vehidle turning on headlights will lower battery voltage in a few seconds and charger should turn on.)
Battery has less than 0.7 volts set to manual and retry
Charger will not turn OFF. Battery has problem and will not take full charge. Have battery checked. (if in MANUAL, switch to AUTOMATIC)
Ammeter needle pulses (fluctuates) every few seconds AFTER THREE HOURS without slowing down. Two or more batteries connected in parallel. Requires more time to charge: continue charging.
Battery of 200 ampere hours or larger Requires more time to charge: continue charging.
Battery is connected to application that draws a small current (such as an auto dome light). Requires more time to charge: continue charging.
Charging current is less than full output rating of charger. Battery is partially charged. Continue charging.
Battery is defective (battery plates are crusted) and will not accept a full charge. Have checked and replace battery.
AC power supply is low Plug charger into another grounded AC outlet.
Ammeter needle moves to extreme right, remains a short time, then returns to zero, accompanied by a clicking sound. Severely discharged battery (but otherwise good battery). Allow charging to continue until battery has recovered suffieiently to take a charge (Circuit breaker will dontinue to cycle and needle will swing side to side until battery has recovered).
In MANUAL with battery connections reversed. Unplug charger and change to correct connections.
Battery is defective (will not accept charge). Have battery checked.
Charger is cycling after circuit breaker overload. Wait until charger automatically resets itself.

Schumacher User Manual Link


When a charging problem arises, make certain that the battery is capable of accepting a normal charge. Double check all connections, AC outlet for a full 120-volts, charger clips for correct polarity and the quality of the connections from the cables to the clips and from the clips to the battery system. The clips must be clean.

When a battery is very cold, partially charged or sulfated, it will not draw the full rated amperes from the charger. It is both dangerous and damaging to a battery to force higher amperage into it than it can effectively use in recharging.
