YC1, I suppose if a manufacturer switched to a thermally conductive potting it would help a lot. But for years it was "over the left shoulder and into the dumpster for burned contact failure" and "Over the right shoulder for burned out coil failures".
I got so tired of addressing this I pushed for using a remote rectifier. End of problems forever. No bird circuits, no contacts, no voltage drop, happier campers.
I agree there is a degree of failure but it is a simple and inexpensive item to diagnose and repair.
