#
Check that the

connected. (If the battery is in a good condition it
would probably pass the test without being fully
charged)

(Before replacing the battery, measure the charging voltage
on the battery leads with the battery disconnected. It must be
between 13.6V and 13.8V, if not, replace the charger.)

Check for badly running gate, or something
obstructing the gate.
