1996 Mariner 200 MAGEFI

[TOTO1]

An intermittent Beep Alarm is going all the time. The manual states oil injection system is the problem. The oil injection system has 2 sensors; one in the oil reservoir on the motor (2 wires Blue and Black) and one sensor on oil pump (3 wires; Black, Blue with white tracer and White) both sensors go to the Black Brain Box which has 7 wires; black, blue with white tracer, white, purple, blue, green, tan blue tracer)

How do I determine what the problem is? The engine seems to run ok with plenty of injection oil.

Test the float in the oil tank to make sure it's not stuck. You might also check the Temp sensor. I believe it ties into the same module at a terminal block on the engine. Check your manual.

I tested the float sensor with an ohm meter and it is working fine. The temperature sensor is connected to a different black brain box (module) and the manual reads that the alarm would be a steady beep if it were temperature related mine is an intermittent beep. HELP
