Great Planes Triton Jr. Charger - GPMM3152 - Manual (Page 22)

PROBLEM: Display does not work when unit. Check power supply for proper power. Check input connections for proper contact.
PROBLEM: Charger doesn’t recognize battery. Make sure battery is not connected backwards. Check for faulty connection
or wiring. Perhaps there is a defective cell in the pack, in which case the pack should be replaced.
PROBLEM: Does not automatically stop charge after 1.5 hours for NiCd/MH batteries, or 2 hours for LiPo/Ion batteries.
Internal problem might exist. Disconnect battery IMMEDIATELY and contact Hobby Services.
PROBLEM: Battery voltage low after charge is completed. Make sure charge current setting isn’t too low. Battery might be defective
and require replacement. Check to see if the backup safety timer expired before full charge was reached. For lithium batteries, make
sure the battery capacity value entered in the programming matches the rated capacity of the battery.
PROBLEM: Will not lock into discharge mode. An improper discharge voltage was entered for the battery. Adjust the battery
voltage in the discharge screen to match the number of cells in the pack. Tx might have a diode in charge circuit, in which
case it’s best to connect the battery to the charger directly (outside of the Tx). Battery might be defective and require
replacement. Battery might already be discharged.
PROBLEM: Low mAh readings after discharge. Batteries might not have been fully charged prior to discharge. Batteries
might have been old or unused for an extended period of time, which may require additional cycles to see if capacity
improves. Battery might be defective and require replacement. Discharge current setting might be too high, and should be
lowered. An improper discharge voltage was entered for the battery. Adjust the battery voltage to the proper value for the
battery. Battery might already be discharged.
PROBLEM: LCD and/ or controls do not function properly. Input power might be connected backwards, and require re-
connection. Input fuse might be blown and require replacement.
