I've got an electrical issue. I can jump start it easily, but the battery isn't getting charged as the mower runs. If I charge the battery, it retains a charge. The last time I used it, it started without help, but an hour later when I stopped to fill the gas tank, it was dead and needed to be jumped. I don't know if I have a loose electrical cable somewhere, a short, or if the generator / alternator is faulty. I have been unable to locate the name, part number or location of the generator / alternator in a diagram, but I think I know the device on my tractor, just need confirmation. Are my symptoms familiar to anyone? Any suggestions for isolating the issue?
