I just serviced my circa 2004 GT235E tractor to start the season. I had to replace the battery. It wouldn't ttake a charge and the positive terminal was corroded beyond anything I have seen before. Started and ran fine with new battery. The wife mowed the lawn with the bagger as usual for the first mowing. I then completed oil change, converted deck to mulching mower, lubed, fluids, cleaned, etc. The mower ran fine without problems. The mower wouldn't start then nest time. With key in run position, the lights are sporadic. The battery light is not always on. I heard a loud click when trying to start several times. The mower then started several times.
Now back to same thing. Nothing when I turn the key. The green LED light is lit on the circuit board connected to the starter switch. I suspect this is a starter switch or ignition board problem? Any help with troubleshooting? I was unable to locate a wiring diagram to help.
