As Ken posted, there should be 12 volts (battery voltage) on the K1 terminal, not 8. This is a common positive relay and the relay action is activated by a switched ground. What happens when you remove the grounding wire? Why is there only 8 volts on the power feed? Measure the resistance to ground on that ground trigger wire after it starts and then you remove it. If removing it does not stop the starter, then there is a ground leak right there at the relay. If the starter stops, check that wire and circuit for a ground leak with your multimeter or test light. If you have 8 volts on THAT wire, then it must be the difference between 8 and 12 that is keeping the relay triggered.
