I have a new to me 31 Model 42 and am in the process of sorting things out. I have discovered that the battery is installed where the negative goes to ground and the positive goes to the starter. I believe that these cars are positive ground cars. I have tested the coil by putting the negative lead on the negative post at the coil and the positive lead on the engine block. when i do that (and crank the engine), i get a positive deflection. I believe this confirms that coil is a positive ground coil. The engine runs fine both cold and warm, but the starter seems a bit lethargic especially on a restart when hot. Therefore i believe i need to reverse the battery cables. What should i do to check to see if generator has been damaged? Is there anything else i need to check? Thanks in advance for your inputs.
