Another Beep, Beep, Beep question!

[bqtoot]

Yes, I've read many, many posts and the FAQs on the subject, but still have questions. Please bear with me.

Engine: '94 Mercury 115hp ELPTO
Mod.#: 1115412PD
S/N: 0G074890

Same problem as everyone else. Turn key on, beep, beep, beep. I know it's oil related (as opposed to steady, beeeep).
The oil tank is full, batteries are spankin' new and fully charged.
Here's what I've done:
Disconnected the 2 blue wires going to tank sensor. Turn key on, beeping stops. That leads me to believe the sensor's bad, but hold on! Jumped the 2 wires going to the sensor together, no beeps. But when I do an ohms (resistance) check on the same wires going to the sensor, I get 000 on my multimeter. If the sensor was bad, shouldn't I get resistance, or at least something other than 000?
Also when I do an ohms check on the warning module, the beeping starts again.
The prospect of ordering both the sensor AND the warning module just to troubleshoot is expensive. I suspect it's the sensor, but........can anyone help?

Re: Another Beep, Beep, Beep question!

If the alarm quits when both wires are disconected from the oil sensor then the sensor is the bad or one of the blue wires is going to another sensor that could be bad and you will need a diagram of the wireing for that motor to tell just where they go. Most service manuals will have that diagram in them and are a cheap investment if working on the motor youself.
