The spring that separates the contacts in a relay is very weak. It seems to me that the spring that returns an ignition switch from the "start" to the "run" position is considerably stronger. Then there is also the option of turning it back manually if needed. In a pick-n-pull yard recently, I removed a starter relay from a Eurovan. I looks a lot like the traditional Ford relay that Dennis advocates. Does anyone know if this was a factory installed improvement or something an owner added? Larry A.
