Generator Test

[mwhetzler]

We have a '47 Chris Craft Special with an ACE engine. Our battery goes dead after a short while. We had the battery tested, and the results showed that the battery was good. We did a quick review of the wire connections and wiring condition and all looked good. We are wondering if it is the generator (or something else). Any suggestions? Is there a simple way to test the generator without having to uninstall it (it looks like the carburetor would have to be removed to provide sufficient clearance to remove the generator). Any suggestions would be appreciated. Thanks
