Another riding lawn mower what did i break on it question....
My 2004 Craftsman 17 HP Kohler single popped the starter relay about 5 years ago.
Super easy fix. Part was cheap. Kind of looks like a "standard/Mopar" relay.
Trace the wires, but mine was mounted on the body near the gas tank, under the hood.
Can't remember if I had to take the gas tank out to replace it.
10-15 minute job.
