Most likely a bad motorcycle battery. Remove the fuse so the battery is connected to nothing (or disconnect one battery connection). Check the battery voltage. Connect your charger and check the battery voltage. If with the charger attached it climbs to almost 14 volts after a while that check is good. Disconnect the charger. If the voltage is not at least 12.6 volts, assuming your meter is good, replace the battery. To double check, do the check across the battery of your car with it running and not running - the motorcycle reading and car readings should be nearly the same.

Standard Digital voltmeters are about worthless for automotive and definity worthless for old motorcycles. A cheap analog meter is much better, unfortunatley all seem to have 10 and 50 dcv ranges when you would like ot have a 20 dcv range. I use this one because it's big enough that battery and charge voltages can be "close enough" read: [MEDIA=amazon]B000O02YRI[/MEDIA]

The battery in a multimeter is only involved when measuring resistance - has nothing to do with dcv, acv, or current.
