Batteries do not fully charge.
If the batteries are charged overnight, make sure the
AC supply is not being switched off at night with other
building items. Check battery condition and for dead
cells or reduced capacity. Replace charger only if other
problems are not found.
The AC line circuit breaker or fuse is blown.
A defective circuit breaker or fuse, an overloaded
circuit, or a charger problem can cause this condition.
Try connecting the charger to a different AC outlet
(on a different circuit) in the building. If the AC supply
checks good, the charger should be replaced.
