A friend hooked up the battery reversing the correct polarities, and now the starter motor does not work. I am told there is a spare fuse stored in the engine, but I cannot find the original fuse or the spare so that I can replace the broken fuse and use the electric starter again. The motor is fine, i.e. the pull cord works, and the battery is fine, too. Thanks for any assistance in locating the fuses. Why doesn't the manual that comes with the motor have a map of the motor in it?
