Re: What breaks when an LB/ Toro coil fails?
The farmers when I was growing up who dealt with tractor coils told me that the copper windings with the thin insulation coating chaff due to thermal expansion and contraction. Once chaffed through after operating temps are reached the copper windings become shorted and at that point of expansion it is a “No-go”, bu let it cool and the coil windings contract and the “Short” goes away and thus the spark returns. With solid state modules there are even more components to fail.
