Abstract
A hydraulic system associated with an engine may include a hydraulic pump, a hydraulic tank, a hydraulic starter and a second pump. The hydraulic system may include a relief valve that allows hydraulic fluid to pass through the relief valve when pressure at the relief valve meets a predetermined pressure. As well, the hydraulic system may include a first solenoid valve and a second solenoid valve. The first solenoid valve may be coupled between the hydraulic pump and the second pump to thereby control fluid flow to the second pump. Additionally, the second solenoid valve may be coupled between the hydraulic pump and the hydraulic starter to thereby control fluid flow to the hydraulic starter.
