Another riding lawn mower what did i break on it question....

Should be a simple trace of the wires continuity test. There's not a lot of wires on those things. My grandfather had a dozen probably I was just riding one of his old ones last month or so. Hes long since passed, '05...but his mowers he loved live on. Now I think I might take in my grandma's cat since she just passed away. Got to fix they're old 66 Lincoln and sell off some of the other cars that have been yard ornaments for 10 years or so.
You might just buy a spool of wire and start bypassing some things cut it out of the loop and make a direct route. Good luck
