I believe that my statement is still accurate in that the hydraulic pressure will fall to below 3000 psi below normal idle speed. I did not say how far below but for argument sake 1/2 or 1% is below normal idle speed and you are certainly not going to get 3000 psi at 1%. Your hydraulic "light" that you refer to is a low pressure light and therefore will go out as the pressure increases to or reduces past a certain level. That light would be set to trigger at BELOW the NORMAL hydraulic pressure. Once again, if the hydraulic pressure(normal) is 3000 psi at idle rpm then it must at some time reduce to less than 3000 psi as the engine goes BELOW the normal idle speed, which is what I said.
