I was installing new gauges in my u diesel and there is a two wire oil pressure switch attached to the oil pressure gauge behind the panel. Any one know what this switch is used for as all the wiring has been removed from this tractor. Thanks
 
All U diesels I have seen whether UTSD-M, UTSd or UBD have a hourmeter. 12v is applied to oil pressure switch. When oil pressure achieved switch closes applying 12v to hourmeter. Also used on UB gas models. Remember there is no way to connect hourmeter to distributor on a diesel. 10A2296.
