Don't run a Model A generator for more than a few seconds if it's not connected to the battery, or it may burn itself up. If the cutout is faulty, then the generator isn't connected to the battery. In case of a faulty cutout, you can safely run the generator by jumping the output post to ground.

Tom, you were right on the money for my French-assembled 29 Tudor's side cutout Powerhouse generator about the polarization. Had a loose field coil that caused a break in the solid wire connection between two of them. Placed a crimp collar across the break and used a pencil soldering torch from Harbor Freight to run some solder down into the collar connecting and stabilizing the break. Motor test off and on the car were fine. No charge when started, however. Had left the back cover off and connected the jumper across the diode cutout I have installed. Some sparks came from the engine side of the back of the generator and I now have good charge level. Believe polarization was the problem. Another one for the mind file of tips and tricks. Thanks for posting here where we novices can find them.
