The EM2  knows that you haven't started the engine yet and it doesn't think you need to be bothered with a flashing alarm about low oil pressure and other out of limit things until after you do.

 Tracy,

I didn’t initially hook up the alarm light on my system as I was concerned that it would be going off all the time while I got everything working.  Well today I hooked it up.  I wired P3-10 to the positive on a 5V LED and P3-2 to the negative side.  When I turned the EM-2 on, the light did not light.  The voltage was low and was flashing, but the alarm light was silent on the issue.  I did not have the EC-2 turned on and the engine was (of course) not running.  Just the EM-2 was on.

 

Is this expected behavior?  I thought the alarm would go off if anything was out of its setting.  The voltage was low so at least something was out.  (I am not concerned about this as I have a low voltage monitor which was telling me at the time that I had low voltage.)

 

Thanks,

Bill B
