Cranked motor as normal. Idled to boat dock killed motor. Now it will not even turn over. On a 2016 Ranger. Push start button, battery and lights go dim but nothing on motor. Batteries has full charge. Reads 13.1volts at starter checked everything all the way back to battery. Full charge. Is it the starter or key pad? Everything else works fine on key pad. Do not know which dealer to bring it too. Mercury mech does not sell ranger and ranger deal only sells Yamaha and does not have a good mercury mech. Any type of help would be greatly appreciated. Also tapped on starter and nothing.
