I was mowing my lawn the other day and I began to smell burning plastic about 30 mins into my mow. I immediately shut the tractor off and popped the hood, and saw smoke coming out from under the flywheel. After removing the flywheel This is what I saw (See pics below!). Has anyone ever heard of this happening, and what might even cause it? Upon close inspection, the black wire did have a tiny sliver of rubber missing, and very small amount of metal exposed. I'm talking less than 1/8 inch. Wondering if it was possibly shorting out as a result? What else could cause such a catastrophic failure? Ive already ordered a new part, but I dont want to install it if something else other than the defect in the cable would cause this. Thanks for your help guys!
