OPERATING INSTRUCTIONS
GENERAL OPERATION
After the AC cord on the charger is plugged in and a battery is connected to the output cable correctly, the Yellow LED will turn
on. After 4 seconds the charger will begin charging the battery. The 4 second delay is added to allow the user to establish a
good connection before the charger output is turned on. This will help prevent unwanted sparks during battery connections.
NOTE: If a RED LED is on, reference the Troubleshooting Section of this manual to determine the reason and take the
necessary corrective action to remedy the situation. If you are unable to remedy the situation and need help, call the
Minn Kota Service Department at 1.800.227.6433 and a technical support representative will be happy to assist you.
