Is my battery dead?

To double check it may be worth charging it whilst disconnected from the bike; since some electrical problems on the bike could lead to a constant drain on the battery whilst the ignition is off. (i.e. leaky diodes in the charging circuit).

A faster test is to use a multi-meter between say the battery +, and the + cable (disconnected from the battery) and check there's no current flowing with the ignition off. Start with about 5A setting just in case, then work down to about 500mA (fsd).

Any current flowing over say 50mA (allowing for alarms/clock etc) suggests there may be an electrical problem other than the battery.
