I have a '27 11b Franklin and since becoming the owner I've had nothing but problems. The engine was completely rebuilt and the carburetor wasn't even though I was charged for it. After having it rebuilt the car can't start and after over cranking it I melted the inside of the starter. That's rebuilt now and now have no power to the electric fuel pump. I don't know how the particular part that I think maybe bad can be tested. Its under the dash behind all the switches and is a black box.
