The slightest bit of looseness results in arcing and oxidation of the contacting surfaces causing voltage drop which the regulator senses so it increases the field voltage to up the alternator output. Eventually at the peak of one of the up/down swings of the voltage, it will spike causing the field breaker to trip via the crowbar OV protection circuit.
