Use of the multimeter I have purchased recently is all new to me. I need to find if a automatic choke on a subaru carberator has voltage or not. It has only one wire going to it. I presume the correct way to check voltage here is to put pos. probe on wire leading to auto. choke and the neg. to a ground such as the engine block. Is this correct?

Your assumption is correct. You will reference your measurement to ground - chassis or engine block in this case.
