So when I hit the switch to raise my from end it will raise on and off. For example..... You'd hear the zrr zrr. Then the click from the solenoid. Then the zrr zrr again from the motor then click again. Then I would have to lower the back for it to lock out?????? Man wtf is wrong I just replaced one battery. I'm running 6. And I recently charged them too. Any ideas or something someone has experienced??
