• 12 •

Green LED is 

flashing and the 

display shows 

BAD BATTERY. 

The battery is 

sulfated.

The battery is too 

large for the charger.

Reset the charger by 

briefly unplugging it.

You need a charger 

with a higher amp 

rate.

The display 

shows CONNECT 

CLAMPS.

The clamps are 

not making a good 

connection.

Check for poor 

connection at battery 

and frame.

• When a charging problem arises, make certain that the battery is capable of 

accepting a normal charge. Double check all connections, the AC outlet for 

a full 120 volts, the charger clamps for correct polarity and the quality of the 

connections from the cables to the clamps and from the clamps to the battery 

system. The clamps must be clean.

• When an UNKNOWN OPERATING PROBLEM arises, please read the 

complete manual and call the customer service number for information.  

This will usually eliminate the need for return.
