Can anyone tell me if a 1985, 150hp,etlk oil module can be tested?
If so how to test.

what color wires are on the engine tank switch assy.
and is this the original design or a replacement since about 2000.

The wires going to the tank sensor are white, brown, red, and black.
The wires going to main connection are green,yellow with red stripe, white,green with tan stripe, black, purple, tan.

unplug the engine oil tank.
turn the key on.
jumper the black to brown on the harness side connector.
pump should run.
now jump black to white, pump should quit. now jump black to red, pump should run,audible should comer on.
what indicates are lit on your tach at key on power.

Thanks I will try this.
My problem is my oil continues to pump into sub tank on engine when key is on.
When engine is tilted it stops.
I have replaced sensor with new one.
Have not replaced oil module, wanted to test first.

check the key on voltage to the module also.
if below about 9 v the module will turn on the pump.
its a quirk but it will.
the module also has a mercury switch in it that shuts the transfer pump off when tilted.
later design used a signal from the pulser coil.
mercury being bad juju.
