It appears that you tested the pumps by connecting them directly to the battery 12 volt source. I am assuming that you disconnected the pumps' electrical connectors on the pumps' electrical connector pigtails. While you had the connectors apart, did you check the other end of the connectors to confirm that you are getting 12 volts to those connectors, when the pump switches are activated?
