automatically detects the voltage

connection.

SOLUTION
No problem; this is normal.
The Green LED will be solid
when the charger is checking
the condition of the battery. This
is normal.
Reset the charger by briefly
unplugging it.
You need a charger with a higher
amp rate.
Check for poor connection at
battery and frame.
Replace the in-line fuse for the
ring connector.
