I am looking at an installation that uses LED's in place of the original incandescent warning lights. In this configuration I am thinking that using an LED as a direct replacement of the original Oil Light would act as a switch and power the fuel pump. So I am looking at using a mini relay to provide the voltage drop required to prevent the pump from running.
Does anyone know whether or not a relay would reduce the current to the pump enough to prevent it from running with a low oil pressure condition?
