    Check your series-parallel switch. It might be stuck. Try and give it a smack with a rubber mallet. See if that helps.

    Then when you figure out that is your problem, which it surly is, buy a new 12V starter. Through all that 12-24V stuff in the trash. It is a good update for about the same money.
