One thing that can make relays and solenoids "chatter" and make a jackhammer sound is not having enough current available to operate them properly. A weak/discharged battery or a poor connection or ground or a corroded switch contact could cause it. In some cases, where a relay operates a motor or other high current device, if the power supply is inadequate, the relay will close, sending power to the device it operates, which then loads the circuit such that the relay starves for current and releases. When it releases, current demand drops and it closes again, repeating the cycle over and over, producing the stuttering or chattering sound. This may have nothing to do with your issue, but it's something to consider.
