Mich. Comp. Laws § 168.736
When an elector applying to vote shall not be challenged, or, having been challenged, if the answers to questions asked him while under oath as to his qualifications shall show that he is a qualified elector at that poll, he shall be permitted to vote. The inspector having charge of the ballots shall deliver to said elector 1 of each kind of said ballots to be voted at the election. All the ballots so given to an elector applying to vote shall bear the same number, beginning, for the first elector to whom ballots are given, with the lowest numbered ballots, the next higher number for the second such elector, and so on. On request of the elector, an inspector may give explanation of the manner of voting, and if by the board deemed necessary, an interpreter may be called, but the elector shall not be otherwise assisted in the marking of his ballot, except as provided in this act for assisted electors.
