I have a walker mower with an electrical problem I cant figure out. I was hoping some one might have some advice for me before I have to pay someone to fix it. The problem Im having is that it doesnt seem to be charging the battery. I spent a good part of today trouble shooting, but got nowhere. It was a new engine this spring, so at this point Im thinking that the magneto and such are in working order. I replaced the battery, it was really old anyway. I redid all of the questionable connectors I saw. I even replaced the ignition switch and electric PTO switch, because they had been finicky a few times this year. So now I can charge the battery, and get about 15 minutes of mowing before the battery gets so low that the electric clutch disengages. Any ideas? It is a single cylinder Kohler Magnum 16 HP.
