Lin -
It's very normal for the terminals on the battery to get corrosion on them
and form an insulation layer to the cable. Take the cables off and run a
battery terminal cleaner over the terminals and in the cable hole. I am
pretty sure that will be your problem. If not also disconnect and reconnect
all ground straps and solenoid / battery switch connections. If that
doesn't fix it than it is quite likely your battery switch has gone on the
fritz and needs to be replaced. Bypass the battery switch in the boot and
see if that makes a difference.
