I own cub cadet mower ad the charging system went out. This I know because after it would not start, I cecked voltage with it running (jumped i off) and had 9.5v-10v. I am familiar with electronics, but I need a schematic or just a ruogh idea. It is a cub 2165 which has a 2 cylinder briggs. Here goes the assumption part. I assume it has a coil around the flywheel and the coil needs power to it to excite it, thus causing it to produce power to keep the battery charged. The part I do not have a grasp on is how it is regulated. Bottom line is this. I do not want to spend 50-100 dollars on a coil, if it is something else. What else do I need to check? Thanks all
