Worst case you might need to go through the entire loom totally randomly would hint to me at an earthing problem, BUT what else might fire that buzzer? (as mentioned low oil if it is an automixer).

I know this may sound suicidal, but why not disconnect the sensor, wrap the connection in tape & motor off (whilst keeping a close eye on the tell tale! ). If you get no alarms then you probably have a faulty sensor.


Other thing - it is the original sensor? There are a fair few that are physically interchangeable but have subtly different trip temps.
it IS a classic, as in that is the model.... google mercury classic ---> [https://www.google.ca/search?q=mercu...sic+40&spell=1

and you'll see what I mean. It is a model Mercury made from late eighties to mid 90's in 40, 50 and 60 size, the difference being that it is a 4 cylinder 2 stroke. (not the typical 2 or 3 cylinder setups)

It is oil injected, however, like I mentioned before it can not be the low oil sensor because it is indicated by and intermittent beep not a constant beep like I am experiencing. Furthermore it is disconnected.

And as I mentioned in the first post I have changed the temp sensor sender with an OEM replacement part.

So I found the cause for the alarm sounding. Turns out it is a wire shorting in the control box. What a relief!

Sorry I never got back - been really busy..... (probably also not unrelated to the reason I missed the fact you changed the sensor! )

I must admit I never knew they did oil injection on the 4 cyl one.....
