Starter Switch

Unknown

Hello. I have been working on my 1929 Hudson Sedan this fall. I

went to start it yesterday and the engine will not turn over. It

appears to have a problem with the starter switch, which is located

under the starter. If I push the starter rod side to side, it will

make contact. How does the rod make contact with the positive lead

and the starter lead? I can see a brass ring on the rod. Can it be

replaced?

Thanks for your help,

Rick
