Re: Oil Pressure Sensor for Volvo Penta 4.3GL
Only one wire sending unit. Owners manual doesn't have anything on wiring diagram or oil sending unit (probably need service manuals). I'll try the ground and see what it does. Thanks for the help. I have pulled the sensor off and cranked it over to see what happened and oil shot up and everywhere. I can also see oil running on top of the heads through the oil fill cap so I know there is some oil pressure. Also, no lifter noise. But I've had lots of problems with this boat so want to find the problem before it turns into something else...
