@Chuggs , I did get an immediate “excess slope” warning on the screen as mentioned in the OP. That is why the the 3000psi switch is in consideration. So, which psi switch is the most likely culprit if it is one of the two?There is also a 50 psi switch on ours. The 50 psi switch closes a signal to ground when 50 psi is reached. It must signal at least 50 psi for valves to open during extension. If your pumps run...but none of the jacks extend...I would start with testing the 50 psi switch. The 3000 psi switch is for excessive slope.
