    Default 520 Wheel Horse not charging

    Hello my neighbors 12 yr old son bought a 520 Wheel horse to mow lawns and make money but nfortunatly it is not charging the battery. I checked and the voltage at the battery is not increasing when the engine is running. Im thinking it is either the voltage regulator or the coils.

    Does anyone know where the voltage regulator is?

    Any idea what typically breaks on this model to cause the battery to not be charged?

    Thanks

    ~ Phil

    What engine is in that? I have a 25Hp Kohler engine that there was a fuse in. I replaced that and it blew out again. Underneath the flywheel was the alternator charging system. One of the magnets had come off and turned into shrapnel under the flywheel I had to replace the coil and flywheel.

    I think mine is charging because It seems to be keeping my battery charged but the gauge never moves to show what's going on. I'll take you up on your offer and PM you. I have some information on the electrical system but you can never have enough info on one of these machines. Thanks!
