You can ground pin 85 on relay K-3 and all works, if you look pin 85 is the ground and comes from the oil pressure sender, so if the light for oil pressure is on then check the engine oil pressure sender but if not then the wire 705 out of the power dist. board to were it hooks up with the 705 wire under the cab to the rightside connector that goes into the cab some place is bad. Ground 705 pin on the power dist. board and you should have lift/raise working, look at the first wire diagram to see this.
