Trying to get enough motion on a ratchet wrench inserted through the change drawer opening to take off the nut on the Main Relay was, for me, impossible. For $29.95, Home Depot sold me a Husky 3/8 ratchet that also rotates the socket by twisting the handle. Just put it over the nut and crank. 6 degree ratcheting, also. Pricey but sweet.
