2012 exmark quest will not start. battery is strong. I cleaned all terminals on battery and on solenoid. When I turn the key I get a strong click coming directly from the solenoid. I tried to cross the posts on the solenoid but it does not spark or turn the starter, As if there is no electricity coming from one post to the other. I do not have an amp meter but I do have a multi-tester. I get 12 volts from battery to post on battery side of the solenoid. I get 12 volts from solenoid on starter side when the key is turned. I am not a real mechanic. I know just enough to get me in trouble. but good enough to follow directions and fix it when I know exactly what is wrong. Please help
