As I said in another post I don't have an ignition key to a 1975 85hp Evinrude. I saw a guy in YouTube bypass the ignition system by connecting jumper cables to the solenoid motor, and the solenoid rod pushed up and engaged the "cog" on top of the motor. When I did the same thing, nothing, but when I connected the cables to the solenoid unit, its "cog shaft" spinned quickly but did not go up to engage the "large cog." How do I use a multimeter to see if either or both units, especially the solenoid motor, are weak or need repair or need to be replaced?
