Sorry for the lack of info. I was in a hurry when I started this thread.
It's a 1997 Craftsman riding tractor (unsure of model) with a Kohler Command 15 HP (M# CV15S) engine in it.
I know for a fact that the solenoid went to hell because when I turn the key it makes a buzzing/ticking noise. I already checked the battery, it is fully charged.
Did you try jumper cables on the battery?
I know you said the battery is good.
Most times when it buzzes or clicks multiple times it is a weak battery or a loose connection. Check and make sure everything is tight and clean.
