I just hooked a pressure gauge up and it stays constant at 43 psi. It ran longer this time and the oil pressure light came on and then went off but did eventually come back on and kill the motor again.

Does anyone know what the resistance should read on the sending unit while the motor is running or have any more ideas.

I have read they should read between 35 and 50ohms so I was considering buying a 40ohm resistor and seeing if the lift will stay running
