Have recently purchased a 2006 Reed 37Z one of the issues I am having with it is, pump will engage and cycle till passunger diff cylinder reaches top of its stroke, then it pressures out without flipping the s-tube.  you can use the JOG switch to flip s-tube back and forth and pump.  It does this every day we use it , for 20,30 40 yards and then when it decices to it will take off and work correctly for a while or the rest of the day. I try to shut down and reboot after a few minutes if waiting on a truck. often once it takes off you can pump rest of day no problem. did two houses today. hand stroked the whole first moved it did fine for the second went to wash out and screwed up again..

   Have changed proximity switches.    Black box.  local reed shop looked at it and said A/B switch isn't working right and doesnt appear original but doesnt think the problem is there.

  Anyone seen this before.

Give REED a call directly, ask to speak to Duane Remus directly.  Mike Wickstrom may be able to help as well.
