i have a 9760sts that when you engage the seperator, it will run for about 1 min then kick itself back off. no codes. checked alternator, appears to be ok. switched unload auger engage solenoid back on main engine gearcase with the seperator engage, still same thing. put auger engage solenoid on seperator engage valve, hit unload auger button, seperator will stay running then. appears my hydraulics are ok. any other suggestions. thanks
