One mode is : It does not do anything
One mode It never goes into "Bulk" or fast mode
One mode It never comes out of fast charge
one mode. it never switches to FLOAT
And that is ONE possible problem you have (The last fail mode not going to float)
IT is also possible the battery (one of the halves) has a shorted cell,
