Hello Nick, Welcome to the ORG. Are you testing the voltage on the supply side of the relay? The one that has voltage all the time? If so you have a bad connection somewhere. Either at the relay or where the power wirr come from. If it has a good 12 volts on the supply side and you are only getting 6 out then yea the relay is bad. You say you are in Mansield.. Is this Texas? If so me too. JJ
