Multimeter isn't the most useful tool to check a generator, you really want an ammeter in line with the output to check, one that goes to atleast 35 amps. Old Motors and other manuals describe good proceedures.

About all you can check with a multimeter is for a voltage increase at the battery as engine rpm increase. For example for 6 volt, the battery at rest should be about 6.6 volts; at about 1500 engine rpm with a load on (put on the headlights) you should get at least 7.2 to 7.6 volts. If you take the generator apart, you can use a multimeter to check for grounded fields or a shorted armature segment.
