if you replaced the motor and your noid is clicking you either got a bad ground or bad noids...check your grounds and connections....then check your noids....if you use the cheapo noids its best to just replace them with new ones since you got a new motor
If the noids are clicking and no power to ur motor. then i would start check the batteries sounds like a bad battery. if u wanna see if its teh noids. take the cable from the workin pump and put it on the other pump motor and see if it will raise then. if not then its not the noids its a battery or batteries. unless u have seperate banks of batteries then u wouldnt be able to see if it was a noid or battery.
to test if its a bad noid. just get a jumper cable and go from the battery post directly to the pump motor. if it does nothing then u have a bad battery and its not the noids
to test for a bad battery, just take one battery out and reconnect the setup, if u nothing happends then put it back in and take the next one out and so forth down the line, just dont forget to keep ur switch power on 24v
