Redbird,
After looking at some of your other posts, you seemed to previously indicate that your truck is currently running a 12 volt battery system.
When you had the "generator" rebuilt, did the rebuilder know you are running 12 volts and not 6 volts?
As others have noted, your '53 was originally a 6 volt system when new, but appears may have been modified to 12 volts (not uncommon) at some point afterwards.
You may want to confirm your generator is a 12 volt unit before going too much farther.
