Re: buzzer beeps (fuel Restriction?)
1994 Evinrude LE 200 SLERS. While engine was idling at dock after inital start up warning horn started beeping a few times in no particular pattern for about 45 seconds. Engine died and started back up and died again. At that point I realized I had shut the fuel line valve off the night before. Opened valve and engine ran fine with no more beeping. After looking in owners manual I see there is a beeping pattern for fuel restriction. I am assuming the closed fuel valve caused the warning horn but what concerns me is that the the beep pattern was erratic and did not match what the manual stated. Anyone have any comments or experience with this.
In a previous V6 Johnson I had, I would get a fuel restriction alarm when I forgot to open the fuel valve fully. (I have a T valve for two tanks). It wouldn't happen until I started going above idle and then would go away if I jumped up and opened the valve and pumped up the primer bulb. But my alarm was steady like it should. As you probably know, that alarm is triggered by a vacuum switch that senses excessive vacuum (i.e. a restriction in fuel supply). My guess is that your vacuum sensor was "feeling" just barely the threshold amount of vacuum at idle and was wavering/irregularly intermittent because the vacuum wasn't great at idle? I wonder if you could duplicate it, but then went above idle if it would change to a steady loud alarm?
That's my guess anyway. Another guess would be a defective vacuum switch? Either way, you heard it and corrected it, so I guess it did its job?
