The engine has been turning over slowly and this morning it will not turn over at all. Replaced the battery thinking it was bad but not the case. Checked to see if sufficient voltage was going to through the solenoid to the starter and it is 12+ volts. So I am guessing it is the starter, but before I replace it I would like to be as sure as possible that is it. Is there an electrical test I can perform on the starter to be sure such as an ohm reading?
