I have read a lot of the old post on precision blend topic and i think i have the process down. I have a yamaha 115ETLH which is an 87 engine. I have a problem where the switch on the remote tank under the center console will not turn off. I have checked the oil sensor on the motor in the main tank and the float moves back and forth fine, does not get stuck. The guage on the tach works where it changes colors through the whole movement of the float.
The color of the wires on the oil sensor are red, black, brown, and white. I have disconnected the sensor and jumped the white to black wire and turned the key to the on position. the switch continues to run and pump oil. I then grounded the white to the main negative block incase the black wasnt grounded and the switch still ran. I have looked over the whole harness and cannot see anywhere where the blue wire could be grounded. I followed it all the way to the motor and it is no where grounded and ends in the oil control unit. I read that if the black wire is connected to the blue or white wire on the sending unit then there is nothing wrong with the unit itself. According to the manual it should be a faulty oil control unit.
Am i missing anything or any other tests that could help before purchasing a part. Not sure if i need to be looking at the guages at all. Any more help would be great, thanks, if i need to add anything just let me know.
