Replaced the brush and realized the the insulator wasn't Insulating. So with the help of a drinking straw I fix the insulator. However, when I turn the wheel there is a spot that will sound the horn. I am guessing that it is the Horn bearing that has a short in it. How do I know or test this before ordering a new one.
Thanks for all your replies

Before doing anything more drastic, I would strongly recommend replacing the insulator. The proper insulator is designed with a specific shoulder that keeps it from contacting the bearing. Using a makeshift fix like a straw likely won't be up to that task and will probably lead to the same issue recurring.
Replacing the bearing is not an easy task as they are usually stuck after being installed for seventy years or so.
