I hooked up the flow divider 1 line in 2 lines out to synchronize 2 rams. When I push the control block, the rams won't move & act like they are fighting each other. We changed the flow dividers, the control box, the pumps, everything I can think of with no new results. This is a very simple system and use the same type system on another machine & it works great. Any ideas as to what the problem is and what I should do next?
