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

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.

mine is doing the same thing, sometimes it charges and then it will stop or go to like 10 volts.i have changed the part behind the flywheel and it didn't help.

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!

My 1990 520H is not charging the battery but operates great in all other aspects. The fuses are good that I can locate. The operators manual does show them but is not much help otherwise. Are you able to share the manual ? I am located in eastern OK County. Thanks Dennis
