Brian,
First I would check the voltage of the battery itself. You should get about
10 volts. If not you either have a bad battery or a problem with your
charger. If the battery checks out, next I would check the poly-switch fuse.
As a matter of fact, if this fuse is blown you won't be able to charge the
battery either so that is the first thing I would check.
