Take the cover off of the aquastat and remove one of the wires on the T terminals. That is the wire from the thermostat. If the relay drops out and the pump stops, you have a pinched thermostat wire and need to run a new one or find the short. If the relay doesn't drop out post back and let us know what does happen.
