My apologies if this is too off the subject of this forum, but you all have answered many questions re my NAA so I thought I'd try. I have a Kohler engine (Craftsman lawn tractor) that will not turn over at all, no sound or anything. Jiggling the wire from Ignition switch to the solenoid? SOMETIMES makes it go something like a grunt. Is there a way to test the solenoid or ignition without replacing them first? The battery is brand new and tests at 12.68 volts and the starter is new.
