I need some advice. I have a 2000 Yamaha HDPI. The on-engine oil tank overfills and dumps oil. I can't get the auxillary tank to stop pumping. I tried disconnecting the wiring harness on the sensor of the on-engine tank and the oil just keeps coming. Thanks

Re: Oil pump won't shut off

Since you disconnected the harness at the engine, the pump is getting grounded some other way. Probably a chafed wire in between the engine and the pump. Carefully check the entire length of the harness from the engine to the auxillary tank(especially in and around the engine as this is the most likely ground source). The most likely area is around the inlet for all of the cables and lines in front of the engine. Good luck hunting.
