I have a '86 black max with 50~60 hours on it. The motor has been/does work great. My question comes with the little warning "beeper" for the oil/temp. Used to be that when you turned the key to "run" the thing beeped a few times, but now it doesn't beep anymore. The last time I took it out I noticed it for the first(?) time, but it still worked fine. I ran all day on it without any problems and am now trying to find out what is going on. I checked the wiring, connections, and beeper and all is well. I am wondering if anyone can explain what might be going on? The only other piece of information that might be of value is that there was a problem in the electric for awhile from a device that was shorting power to ground in trace amounts.... But I don't think that would hurt it?<br /><br />Also, if someone could explain how the "beeper" circuit works? On this engine, there is all of the normal wires to the "fuel inj warning mod" (which consists of two sensor wires to the fuel pump, two sensor wires (one to the unit, one to neutral) for the oil reservoir, one black from the module to neutral, one purple to the module that gets power once the key goes to "run", green wire from switchbox, and offbrownish color going back to the wiring loom.<br /><br />What confuses me is the offbrownish wire. It goes from the module, to a termination point on the engine, to the loom. Also on that termination point, it connects to a black wire which makes its way right underneath the top spark plug on the right hand side fastened behind a little plate (when looking from behind the engine). This is where it confuses me... What does that circuit (The offbrownish that connects to the beeper and that "block-wire") do? How the manufacturer hooked up the beeper behind the dash originally was that the brown wire from the engine was on the "-" side of the beeper and the "+" side was connected to the positive power terminal on the dashes electric distro plate. This must mean that that "fuel inj warning mod" box has a relay or the like in it which connects the brown wire to neutral.<br /><br />That doesn't really make sense; I would have expected the box to supply voltage to the beeper, which would have meant it was pumping its voltage to the dashes voltage. But the beeper worked (and still does if taken out and jumped to the batter terminals), so it couldn't be that way.... could it?<br /><br /><br />Any help you guys could provide would be very greatly appreciated - I am mechanically and electrically very proficient, but haven't had to work on an outboard before.<br /><br />Karl P
