Replaced battery in craftsman lawnmower 42" deck rider model 247203744.
Started up fine. Rode it for about 20 minutes... boom caught on fire under the seat by battery. I am thinking the positive cable caught on fire and spread. Now I have two charred cables and no idea what caused this.
I have replaced maybe 100 batteries in my life. This is pretty basic... I did not look for any issues with the cables, as they looked fine and didn't see anything.
The lawnmower's only other issue is that it sputters. It runs and then after 10-15 mins will just die and need to restart. Sometimes it picks back up on its own. And sometimes runs fine the whole time.
Do I need to test something before putting new cables in? Can they be "repaired"? And how do you get to the positive cable connector without taking the whole thing apart?
