Battery charging problem

[amweath]

I have a Freedom 25 inverter/charger with the remote panel. Since I've
had this coach starting the generator has always initiated battery
charging. The remote graph would show carging at 70 or 80 amps at
14.5 volts. This rate would continue for at least an hour at which
time the charge rate would drop to about 40 amps. Later on the rate
would drop to 10 or 20 amps.

Now the initail charge rate is about 40 amps for about 5 min. Then the
rate drops to 20 amps. My batterys are not getting carged. They won't
start the coach.

Is my inverter charger faulty? I don't know. Any ideas would be welcome.
