Oil Warning Module

[wkos]

I've reviewed previous posts but haven't been able to find an answer so I'll try again. <br /><br />1988 Mercury 175hp V6 with oil injection.<br /><br />Is there any way to determine if the oil warning module is bad? I do not get the 3 beeps when I turn the key. I have 12v on the purple at the buzzer. If I ground the tan/blue from overheat sensor, I get a buzz.<br /><br />Should I just replace the module or is there somethng I'm overlooking?<br /><br />Thanks

make sure all the other wires are attached to the module and that the module has a good ground and 12v power on the purple wire to the module. if all checks out odds are its the module.

I removed my oil injection and did away with buzzer.Premix and don't have to worry with any of that mess.

I've got 12v on the purple at the module and a good ground.... guess I have to bite the bullet and buy a new module..... ouch!<br /><br />Thanks for the info.
